Ein Keter Sophaur

"The burning sun that illuminates the heavens, shining the way a clear path to true justice."

- Zeta

Ein Keter Sophaur (アイン・ケーター・ソファール, Ain Kētā Sofāru), also known as Ein (アイン, Ain), is one of the Vice Admirals in the Marines, considered to be one of its more powerful members due to a combination of his innate capabilities and the swift mastery of his Devil Fruit powers — leading to him being known as the "Heavenly Sun Deity" (天津陽神, Amatsuyōgami), to the general public. Like certain members, he's addressed by a certain nickname, his being Kin'yō (金陽, lit. "Golden Sun") — likened to the sun itself in various aspects.

A born with abnormally large wings, he was hailed as a godlike emissary by residents of the  and was raised by the current. For most of his life, he served in — administering justice and retribution on his behalf, noted by his title as the "Burning Eminence of God" (神の熱猊, Kami no Netsugei). Eventually becoming its leader, his power grew to a point where others believed he will supersede God — christening him with the nickname, Ishinryoku (以神力, lit. "Power Beyond God"), much to his chagrin. Worshipped in the same vein as the current God, his presence brought uneasiness to the one he served under — especially when he obtained and mastered his Devil Fruit powers. At the climax of Skypeia's latest war, he lost everything of value and was critically injured, making his way into the.

Joining the Marines and rising through the ranks, his previous combat experiences and leadership skills proved to be an incredible boon to the organization; admired by various Marine operatives, he's been called the "Guardian Angel of the Just Seas" (正当海の守護天使, Seitōkai no Shugotenshi) — his angelic figure making others believe he was sent to lead the Marines to victory and that "God" was on the side of justice.

Appearance
As one born with great power, Ein's a man who exudes it in every facet of his personage — alluding to his position as one who's born of "God's power", despite it being the source of his downfall and exile from his homeland. Noted to be an attractive individual that matched his kind-hearted, loyal, and virtuous yet naive personality, he's gained an immense following during his tenure as the leader of God's army and later as a Vice Admiral in the Marines — easily making many friends and love interests in both organizations.

Something that mostly catches one's eye about Ein is the glow he emits from his presence, noted to be rather uplifting to most dour moods, so much so that he's often called a "mood killer" with some stating that "It's difficult to be depressed around him. I'm not sure why, but his vibe makes me see the better half of the situation." Ein himself recognizes this trait, which he states is derived from his personality, not his Devil Fruit powers — as some believe, and one of the reasons he makes for an excellent leader, supporter, and companion. He's one of the taller Marines, towering over normal humans — but naturally surpassed by Large Humans and Giants respectively. His fair skin, noticeable facial stubble that's noted to be rather ticklish when Ein rubs his face up against someone when giving out his famed hugs, and darker complexion are often matched with his large, sturdy, well-built, and very muscular frame — noted by his veiny arms, thick chest, legs, and neck, and six-pack abs, honed through years of harsh training, combat, and exposure to the natural elements. Ein's silvery waist length curly hair has a bright sheen when a light is reflected on it, parted on the right side of his face; when he finds that his hair is getting too long or is simply a nuisance, he often cuts it shorter — becoming messier in design, but will regrow it to its original length using the Life Return. He notes that people find him attractive with both long and short hair and often prefers it shorter for battle purposes. His most unique trait is his angelic wings; while Skypeians, Shandorians, and Birkans are noted for their wings — being natural inhabitants of the sky, Ein's is noted to be especially large — continuously growing and expanding since his conception. It was a clear sign that he was more powerful than the rest of his kind, as no one's wings grew at the same rate he did, if at all. Originally white, upon consuming his Devil Fruit and continuously being exposed to the sun's rays, they've gained a golden color and noted to have a warm and fluffy feel to them. Currently, he has seven pairs of large wings — making him look like a, which is dyed in the various colors of the sun whenever he employs his "awakened powers".

Over the course of his lifetime, Ein donned various outfits and armors — noted to enhance his overall appearance; personally crafted and tailored, his wardrobe is to contour to his unique physiology and handle his immense powers. During his time as the leader of God's army, he wore a unique set of gold and whiter armor — containing many pointed edges, angelic wing-like designs, and an arch shaped in the sun's rays. In his youth, and later his de-powered form, he wears a long overcoat that's broken into three sections: white in the middle, and blue on each side; there's a series of buttons on both his sleeves and in the middle. His pants are unique, having various creases near the sleeves, which paired with a pair of golden toe-pointed footwear.

As a Vice Admiral, he wears two outfits: one for battle and the other for his normal duties. When performing his normal duties, a red noble-style high collar golden line shirt with high collar overcoat with a golden line at the wrist that is lapsed with a golden belt, white pants, and white shoes. His battle outfit is less dignified, being a cross of his Marine uniform and his tribal wear; wearing a silver cuirass that leaves his arms exposed, it has a unique designed collar and has a design of the sun in the middle of its chest, the rays are replaced with angelic wings. In addition, the Marine symbol is plastered on its back. Wearing a flowing sash tied to his waist, his white pants have vambraces attached to them — having jewel-embedded amulets attached to the kneecaps, with low-heel sabatons acting as his footwear.

Personality
"For the sake of others, I have to keep shining on. Just like the sun..."

- Ein's resolve to remain positive.

If there are two words that describe Ein, it's "positivity" and "charisma"; despite his various misfortunes, Ein has remained positive and looked towards the future, using his "mistakes" to not only motivate himself but others as well so that everyone can reach a brighter future. It's unknown if such an upbeat attitude is due to the effects of his Devil Fruit, his "great power", or something that's natural but because of it, he's changed the lives of those fortunate enough to meet him, so much so that a select few take after him in some regard, showing how much of a positive influence he is on others. It's for this very reason that Ein doesn't have trouble making friends and allies, even if they happen to be enemies — some of whom show a mutual respect towards him for a variety of reasons.

Striving to be like the sun itself, Ein's a man with a bright, uplifting, and cheerful personality — seen with the genuine, catlike grin plastered on his face most of the time; combined with his innate warmth emanating from the radiance he constantly gives off because of his Devil Fruit, his presence is synonymous with safety and reassurance as most would feel comfortable when he's around. Originally, Ein stated that there are those that are rather... offput by his general display of kindness when meeting him — a natural reaction, but as they slowly get to know him, they know he's an honest and genuine person who has the best intentions for everyone. This is a vast contrast to his younger self, who was timid and distant from people — isolated from others for a brief period because of his immense power; however, upon seeing how kind his fellow Skypeians were, he steadily made the change until he became his current self.

Magnanimous and noble, Ein is one who puts others before himself — helping out those in need whenever the situation arises; from giving them advice to performing certain activities on their behalf, Ein tries to be useful to the people around him in any given capacity, all of which is done with his signature genuine smile and warm aura — to a point where he's often called a "saint" and believing that he's an actual angel. This generosity stems from his teachings by the "God" he served, stating that Ein's power is for the people and him, with selfishness being a sin; to this extent, Ein doesn't harbor personal desires and never acts on self-interest — believing that if he does, it would be a severe betrayal to his character and given purpose. Complimenting such traits, he's noted for being a humble individual — not a single ounce of hubris in his words, actions, nor accomplishments, as humility is an important part of being positive. Without humility, people would easily be led astray and fall prey to their own actions; as one vowing to become like the sun, illuminating on various people's paths, he finds hubris to be a major weakness and often chastises people who show too much pride in themselves and their actions, doing so in a wise manner. His modesty, patience, friendly, and righteousness makes him very sociable.

As one who served "God" as his messenger and an enforcer of both justice and order in Skypeia, Ein is a natural leader — one capable of taking charge at any given moment; his leadership experience is due to him commanding God's Army for many years, utilizing each aspect's strengths and weaknesses effectively and turning the group into a well-organized and effective militia. Inside and outside of combat, the army proved to be strong under his guidance, capable of repelling even the most powerful adversaries and maintaining the status quo. During these charring times, Ein's persona momentarily changes from kind and gentle to stern and serious — cutting down any debauchery in his men to ensure the best possible outcome while not tarnishing "God" in any manner. As he climbed the Marine ladder, it's been noted by various high and low-ranking Marines that Ein's leadership capabilities far surpasses most; in response, he states that it's possible through keen observation of his allies, the enemies, his surroundings, and his resources, using all of them in tandem with one another with swift precision and judgment — a perilous feat under strenuous circumstances. Capable of "reading the air", Ein acts upon tension and proceeds with caution, as the slightest mishaps would make things worse; he makes sure to dial down his positivity when necessary and be more empathetic. Though powerful alone, he's more so when working together with his allies. As a warrior, he's known for his frankness and his utter fearlessness, remaining unfazed in front of enemies that would normally instill fear into those around him, most likely due to his battle experience and harsh training; by extension, he has an incredibly large and strong will, one of the few naturally resistant to the conqueror's shade — comparable to that of an Admiral or one of the Yonko, even though he doesn't have it himself because of his passivity.

Typically, if one were to ascertain Ein's brand of justice, it would be "Moral Justice" — seeing how he puts the welfare of the innocent over everything else and being a worrisome individual; wise to the history of the Marines, he believes that Absolute Justice shouldn't exist because it's no different from wanting to conquer and independence is an important factor for growth. He also believed in the Fleet Admiral's Balanced Peace — good and evil being two sides of the same coin. Due to the justice he exercises, he takes his position rather seriously — doing what needs to be done for the Marine cause; however, he's rationale in his beliefs as he recognizes the errors in certain actions the organization takes. His kind personality extends towards everyone.... except for the Celestial Dragons, the Cipher Pol, and the higher echelon of the World Government. When it comes to the three groups — standard hypocrites who constantly trample on justice for the sake of their goals, and even cover up their actions for the sake of "justice" — bastardizing the word altogether, he shows zero sympathies for any negative actions against them, believing it to be divine retribution. This unfettered hatred stems from seeing the various horrific acts they perform viewed through the sun's rays via his brand of Kenbunshoku Haki. Though not outwardly expressed, he's rather uncomfortable in the presence of anyone from the three groups, and often cursing himself for being unable to impede their actions in the slightest.

As one craving to learn about his "new world", Ein's naturally naive to various aspects of the Blue Seas, often requiring the knowledge of other Marines to fill him in since he never left Skypeia until his exile. When presented with something foreign, a quizzical expression decorated his face, causing others' opinions of him being "perfect" to shatter; this has become somewhat of a running gag amongst the Marines, often fooling him by telling him "interesting facts" about the Blue Seas which usually with humorous repercussions at his expense. However, some would find his innocence and cluelessness somewhat adorable, likening that to a child. If there's one thing that doesn't change, it's his generosity towards children and the elderly; whether it's Skypeia or in the Blue Seas, Ein treats his elders with respect and treats children with the utmost care — acting as a parental figure and a sibling; he was often surrounded by elderly people during his childhood — assisting them in their troubles and didn't get a chance to play with kids his age, encouraging him to do both to both make-up for and reminisce on old times. The image as the "sun" apparent, there's a side that he doesn't show in front of others; due to the various mishaps that Ein went through, he has social issues that he desperately tries to remedy. Though he tries to be useful to others, he also tries not to burden them with his troubles; this causes a sense of isolation — apparent throughout his life. As a being born with great power, Ein's been placed on a pedestal far above everyone else — lauding him as something beyond the mundane. With very few capable of understanding his plight, it became impossible to convey his thoughts to others without them thinking he's being haughty — leading to an inward bottling of his problems, creating unhealthy unconscious behavioral patterns like constant apologies. In addition, his self-appointed role has stifled him from venting his emotions when necessary; when combined with his memory loss and his desperation from figuring out his true identity, Ein would periodically have mental breakdowns that would be so severe that it would cause his powers to go berserk, destroying everything within a given vicinity. Thus, whenever he's at a "breaking point", he would always be somewhere that's void of any life, not wanting to risk the safety of others; in addition, such need to put others before himself makes Ein very protective of his current friends and makes him hold very little value to his own life. This carelessness can be seen in how Ein can plow through armies without tiring, apathetic to the serious injuries he sustains whilst cutting down his enemies, all for the sake of saving his comrades — even though there were better ways to go about it.

In terms of hobbies, Ein's somewhat of a health-nut — always doing his best to stay in shape and encourages others to do the same; he knows much about diets from the books he's read and often applies it to some of his daily routines. While being an excellent cook and cleaner in his right, being used to taking care of others — giving off paternal vibes when doing so, he's noted to be a heavy eater because of his high metabolism caused by his Devil Fruit; this is seen by the various large portions normally served to him upon request, scarfing them down at such speeds that it borders voracious and comically frightens others. He's noted to be one of the Marine's most notable gluttons, giving contrast to his gentle appearance but rightfully serves as a requirement for both his immense physicality and equally immense power. Having been raised on the battlefield, he's a genuine battle freak and often seeks out conflict to prove his skills; he often challenges those with greater power frequently, and those with lower power in groups. However, he recognizes his limits and uses his battle experience to improve himself; in addition, when he's not working or on missions, he trains quite often to hone his skills. Like most Skypeians, Ein is both religious and superstitious; he often prays to his "God", confirmed to be the first "God" of Skypeia, as well as perform his various religious practices associated with his homeland — all of which he takes very seriously. This even extends to his duties, seen whenever he captures a criminal, always hoping for their salvation by God's hands.

History
"If I had any single regret for both the years of servitude to both my people and my God and the countless heroic deeds that have transpired in my wake... it's that I'm falling... literally."

- Ein's life flashing before his eyes before his "fall from grace."

Originally born in under unknown circumstances, Ein was granted incredible power since his conception, which led to him being worshiped as the reincarnation of a heavenly divinity — his name given to him by the elders who've cared for him emphasizing this fact. Though many warriors and elders had sensed his powers and were drawn to him, wishing to pay their respects, Ein gained the attention of the current "God", who descended to witnessed the power that drawn even him; under his orders, Ein was raised under strict supervision, with the intention that his latent talents be used for both "God" and Skypeia's benefit, especially in the face of the rivalling Sky Island territories who wish to upset the balance and subjugate the others to prove their might.

Throughout his childhood, Ein life was comfortable — gaining every luxury he ever wanted, yet strict — disciplined to adhere to Skypeia's teachings and customs, especially when it came to serving "God"; with his bright and noble personality, he gained many friends and a few romantic interests. Regardless, he always felt different than them, emphasized by not only his comparison of wing sizes, having more pairs and being slightly larger, but the feeling of him being watched constantly to the point where it was blaring. Upon reaching the "warrior age", Ein's training was incredibly harsh, even amongst warrior candidates — often receiving private lessons and given unique conditions during training drills on "God"'s orders. Though he struggled like everyone else, his charisma, dedication, and incredibly strong will allowed him to pull through and gain admittance into "God's Army". The dream that was instilled into him since his youth has been realized, much to his pleasure and others in Skypeia.

Residing in the Upper Yard, Ein continually trained himself and performed amicably on the missions given to him — administering justice across Skypeia on "God"'s behalf while furthering the country's development, acting as a "Symbol of Hope". Eventually, after years of cultivation and earning the trust and recognition of both his comrades and people, he became the leader of "God"'s army and became of his deity's right hands. Around this time, Ein was chosen by the three sacred treasures and consumed the Teri Teri no Mi, all of which he found by chance but were used to further bolster his already immense power and influence. He often spent time in isolation to harness and understand these treasures, which led to him developing his current arsenal; eventually, said treasures led to him rediscovering the Seraphic Arts in the depths of Shandora's ruins, which many in Skypeia and the surrounding Sky Island territories were thought to have been lost, reachable because of Ein's possession of the three Holy Relics. Wanting to reawaken such a valuable form of combat, Ein copied down the inscriptions and handed his findings to "God" — which he later spread amongst those in his army; Ein was credited for his latest discovery, which caused the territories to become more and more wary of Skypeia.

At some point, Ein's powers had surpassed the current "God" completely; this was noticeable by not only his comrades but citizens as well, with most giving him the alias Ishinryoku (以神力, lit. "Power Beyond God"). This led to the belief that he would eventually replace the current "God", something that Ein never considered, given his piety because of both his childhood teachings and the way "God" ruled Skypeia with impartiality and kindness, but considered the option should the need arise. Even though "God" was a bit unsettled at both Ein's alias and their assumption of him being replaced, which bordered blasphemy, he recognized that he was mortal thus the mantle needed to be passed; Ein possessed all the requirements needed to rule Skypeia, thus wasn't totally against the idea. However... this was never meant to be, sadly, as the territory was about to face one of the greatest conflicts in its history, resulting in severe losses, Ein being a part of them.

During the time he administered justice, he intervened in the affairs of other Sky Island Territories, as their actions had disrupted Skypeia's order to various degrees; Ein had either defeated, captured, or slain many warriors and criminals from the other islands, flaunting "God" and the country's power while doing so on his leader's orders. Despite his charisma and nobility, he earned a variety of enemies — among them included the leaders of each Sky Island Territory, who felt that his abnormal growth of power would give Skypeia a chance to trounce the other islands, claiming and assimilating them into itself until Skypeia became the sole ruling Sky Island nation. Thus, in order to prevent that possibility from occurring, they banded together and formed a coalition with the sole purpose of eliminating both Skypeia and Ein. The allied nations making a preemptive strike, resulting in civilian losses, this triggered the five-year war that ravaged the sky islands.

In the short timespan, Ein has lost many things that were precious to him; taking its place were feelings of regret, hatred, and desperation — which were shared by many people on both sides. Wanting to put an end to the senseless violence, he pleaded with "God" to launch a powerful blow using the remainders of the army and a "secret skill" recently developed by "God" for emergency purposes; originally against the idea, not knowing the consequences of casting it, he eventually gave in after listening to the distressful cries of his people and seeing the progress made over the last few centuries laid waste in a short span. In what could be labeled as the "final battle", Ein was able to reign victorious over the remaining members of the opposing army — facing off against the leaders while his master prepares the spell. Lasting for a full twelve hours, he reigned victorious — slaying the alliance leaders, but coming with a cost; the damage dealt with him was too great, and near the edge of a Sky Island Territory, he lost consciousness and fell into the Blue Seas as his life flashed before his eyes; eventually, "God" cast his spell which brought an end to the horrific war, destroying most of the surrounding lands and leaving Skypeia virtually untouched. There was a massive funeral held on to mourn those that were lost, with emphasis placed on Ein because of his heroics and being Skypeia's "Symbol of Peace".

To his people, Ein had "died", but in actuality, it wasn't the case; thankfully, he landed on a fortified mercenary crate ship that was capable of withstanding the impact of his fall. Even more so, the captain and his crew had treated his injuries and escorted him to safety; now having amnesia, losing a large portion of his memories, he wanders the Blue Seas — exploring his new home, helping many out using his powers, and trying to piece his memories together to figure out his original purpose. His exploration led to him awakening a special of Kenbunshoku Haki called "Vision of the Sun" — allowing him to link his vision to the Sun itself, viewing wherever the Sun shines its light. It's through the honing of this unique variant that he was able to learn much about the Blue Seas. However, upon learning the existence of Pirates and Marines, he naturally sided with the Marines witnessing the wickedness of piracy on various areas; as if fortune was smiling down on him, he was recruited by a Vice Admiral — admiring his deeds, views, and most notably his powers. Agreeing to their proposal, over the next few years, Ein would join and rise through the ranks of the organization, becoming a Vice Admiral himself, being one of the more popular ones for his kindness, nobility, and reasonable sense of justice.

Equipment
Curolestos (, lit. "White-Stained Evil Cutter"): Curolestos, alternatively known as the "Holy Sky Sword" (聖空刀, Seikūtō), is one of the three sacred treasures of the Upper Yard, and Ein's primary offensive weapon; according to certain stories told by the Skypeians, this weapon belonged to the first "God" of Skypeia — using its powers, along with the shield to quell the chaos that consumed the country. Sometime after their passing, the sword has been passed down to each God who ruled the Upper Yard — a symbol of their authority over all residents of the sky; however, at some point, the sword gained a degree of sentience — inheriting the will of its creator and began choosing those it deemed worthy. Due to his power surpassing the current God and recognizing his compassion, leadership, and dedication towards his people, Curolestos came into Ein's possession — wielding in rare instances.

The sword itself is resplendent, with the entire hilt being gilded and extremely ornate. The pommel is a piece based off many European imperial crowns. It consists of an ormolu crown-shaped base emblazoned with the image of knights and topped off with with a solid rose gold cross. It is separated from the grip by a brass and silver wire ring. The grip itself is polished bronze emblazoned with gold leaf angels. The crossguard of the sword is symmetrical triangular gold spikes. Nestled in the middle of the cross guard is a large ruby. Being a Zweihänder, the hilt extends beyond the cross guard. It takes the form of a bronze cast of the top end of an actual sword, with six rose gold plated grooves fitted with cut rubies. The actual blade begins as a forked snow white steel, engraved with a pattern of twisting parallel lines, highlighted with gold paint. Ein noted that Curolestos emanates a powerful glow from its person, having been bathed in light for many centuries since its conception — alluding to its incredible powers.

Despite being rightfully classified as a Meito, its overall capabilities surpasses normal swords; this is especially seen whenever Ein employs the Seraphic Arts (, lit. "Divine Battle Formation of the Heavenly Winged Generals") — a long-forgotten Skypeian combat style associated with the country's founding. As its name suggests, the sword is effective against those who are "stained with evil" — causing greater damage; aside from its absurd cutting capabilities, slicing through extremely tough and durable substances like a hot knife through butter — exerting little to no strength on the user's part, it's affiliated with the light element, absorbing and releasing it in any given manner. It's to this extent that the sword best suits Ein's fighting style, making full use of his Devil Fruit's capabilities. Forged using an unknown metal said to be beyond anything located in the Blue Seas, Grand Line, or the New World, Ein confirms that the sword will never rust, repels all dirt and blood that touches its surface, and hasn't shattered since its genesis according to records; if a normal blacksmith were to analyze the sword, they would comment it would fail to meet the standards of a normal sword or any weapon for that matter. Normally kept in an equally elegant sheath, Curolestos is employed in certain attacks utilizing either his Devil Fruit techniques or in tandem with the other sacred treasures.

Herugrim (, lit. "Holy Mother's Eclipsed Affection"): Herugrim, also known as the "Sun-Moon Illumination Dial" (日月照盾, Jitsugetsu Terutate), is one of the three sacred treasures of the Upper Yard, and Ein's primary defensive weapon; unlike the sword that belonged to the first God, the shield is believed to have been forged by an adversary who wanted to fend off the sword's incredible powers. However, during one of the battles after the shield's creation, though he was successful at fending off the attack, the shield's power overwhelmed and destroyed him — leaving the shield in the first God's possession; he believed that the shield's existence was necessary should the sword's power run rampant and re-designed it using the Seraphic Arts for the sole purpose of reigning in the blade. It's said that whenever the sword appears, the shield is not far off — a statement proven true as Ein confirms that he found the shield shortly after he obtained the blade; when not in use, it dissipates into light that's absorbed and emitted from Ein's body like its counterpart — called upon when his master deems necessary.

The shield has two distinct form: an active and inactive state, interchangeable with the amount of light poured into it. In its inactive form, it's a large ornate shield that has a dull gold and silver coloration and possesses various floral designs on its surface. There are three layers of designs to the shield. The outer layer bordering the edges, there are various bumpy indents that create an intricate design which stops at a set of curvaceous waves, the tips have ballpoint shapes and circles between each indent. The middle layer has thick vine-based designs that circumvent in an odd manner and possess many-edged leaves that have openings at the base — each one bordering each of the lotus blossoms at each corner. The inner layer has a very complex gold and silver design extending outwards to the middle layer, with golden designs near the tips and at certain points of the aforementioned lotuses. In its active state, the shield changes in its entirety — losing its dull design and coloration in exchange for a brighter shade of gold, seraphic wing-like designs on its edges, and a simplistic circular and rose-like design etched onto its surface. The glow emanating from its being is said to be as intense as the sword, which Ein can freely control utilizing his Devil Fruit powers.

Matching its eloquent appearance, true to its purpose, the shield is said to be as strong as its counterpart — often enacting the. It's said that by assimilating large amounts of light, the shield can erect barriers that induce a variety of "holy-based effects", such as purification, defense, and abilities of a similar nature. Like the sword, it's potential comes in full force when employed using the Seraphic Arts; in addition, since its dependent on light for functionality, it's a perfect match for Ein by making full use of his Devil Fruit's capabilities. Due to it being forged through methods foreign to the Blue Seas, Grand Line, or the New World, it's difficult for most to comprehend its nature and would naturally call it a "failure". In addition, it will never rust, repels all dirt and blood that touches its surface, and hasn't shattered since its genesis according to records. Whenever it's not used, it disappears as a light that's absorbed and emitted from Ein's body like its counterpart — called upon when his master deems necessary.

Zelsinaul (, lit. "Farthest Heavens Virtuous Core"): Zelsinaul, alternatively known as the "Jewelled Spirit of God of the Upper Yard" (神島の神格の宝珠気, Kamishima no Shinkaku no Hōshuki), is the third and final sacred treasure in Ein's possession — his hidden trump card when all else fails. According to legend, the orb is the crystallized spirit of the first Skypeian God, wanting to watch the progression of the nation he saved and presided over for many years; as a spirit, it resides in Skypeians that it deems worthy to rule Skypeia or believes to be able to change the world below in some way. Ein hypothesizes that it was the source of his immense power and growth. Said to be located in his heart, it's a small brilliant orb with intricate patterns on its surface that holds a unique meaning to the Skypeian residents; as its composed of light, Ein can summon it at will — confirming that there are times where it presents itself, specifically if it believes that its current host's life is in danger, using its powers to preserve them. Despite its compact size, the power it exudes far exceeds the combination of Curolestos and Herugrim respectively — typical of their master. Only through the Seraphic Arts that its power comes to fruition, acting as an extension of Ein himself and multiplying his power and skill to various degrees. According to Ein, it's best employed near strong sources of light or near the height of noon, as it's able to draw on its full potential much easier.

Quotes

 * (Catchphrase) "The sun shines on my victory. Yours, however, is looking bleak. Feel the wrath... of the sun!"
 * (Ein touring the Human World with his fellow Marine officers) "I may not know much about the Human Realm, but one thing's for sure — humans are a curious species. I'm glad I came to this world; I get the genuine experience of what it's like to be human. I just hope I don't screw up!"
 * (About Kurama and Quill Pencilio) "Though those two argue a lot, even I can tell they care deeply for one another. I wish I could find a friend that I can argue with like that. It means that I would have someone that would truly care for me and vice-versa. I just hope I can meet them someday."
 * (Ein's charity on display) "Put others before yourself; if you do, then they will return the favor. This is important in building and maintaining strong, and potentially long-lasting relationships."
 * (Ein's view on camaraderie) "Comrades, they're precious. They're people who are always there for you, no matter what; when you're sad, they're sad. Same thing when being happy or angry. They give each other a helping hand, regardless of the situation. Sure, you may have fights here and there because you may share different views on certain subjects, but you're able to put that aside; it's because you know that's not what defines your relationship. When one is lost in the darkness and can't find their way, the other will be the "light" — using everything they possess to guide them back on the right path. Comrades are a super special thing to have; without them, having an adventure wouldn't be as fun really."
