Kiryo Kiryo no Mi

The Kiryo Kiryo no Mi is a Devil Fruit that, in a sense, allows the user to manipulate life via their. Affra Amethyst was the most recent individual to devour this fruit and gain it's power to grant life to those around her, making her the Will Human(意力人間 Iryoku Ningen).

Etymology

 * Kiryo is derived from Kiryoku (気力) which means Vigor, Vitality, or even Willpower.

Strengths
The main advantage and application of the Kiryo Kiryo no Mi is that it allows the user to heal the injuries of the user and those around them. Mostly done via physical contact, it enables the user to fully heal even some of the most fatal strikes. However, healing one's self has a whole other array of benefits such as allowing the user to battle longer than they usually would be able to and essentially revert any damage done to them.

Amethyst also states that this fruit made it much easier for her to learn to use Haki, stating that the process of healing via the Kiryo Kiryo no Mi is done by manipulating the life force, AKA the Haki, in an individual and using it to hyper accelerate the body's healing process. This gave her an early edge on knowing how to detect, visualize, and even manipulate Haki.

The healing can be done in one of two ways, in most cases, the Haki of whomever is being healed is utilized to accelerate the healing process. However, in the case that the patient doesn't have enough Haki, Amethyst is capable of using her own Haki to heal another person.

Amethyst has also shown the ability to use this Devil Fruit's abilities to temporarily physically augment herself.

By far one of the biggest advantages of the Kiryo Kiryo no Mi is it's ability to manipulate life. In most cases, this involves the accelerating of growth in an individual which led to the creation of Pluto Grave. However, Amethyst also displays the ability to create life out of non-living things utilizing the Kiryo Kiryo no Mi. Amethyst states that how she does so is similar to the case of the, in which she grants an abiotic structure a soul, allowing them to live as their own person. Not only does this give the resulted creation life, but due to gaining a soul, they also gain the ability to use Haki which is an inherent trait among all life.

Weaknesses
As the Kiryo Kiryo no Mi is a Devil Fruit that requires Haki to use, it can be difficult for those who aren't too knowledged on the subject to use the fruit. Furthermore, the process of healing with the fruit drains the Haki of whomever it is taking effect upon. This often means that using the fruit mid-combat limits Amethyst's Haki more than it would without the fruit. Lastly, although not entirely requiring contact, this fruit's potential is at it's most effective when contact is being made between the user and whomever the intended target is.

Due to the injuries the Kiryo Kiryo no Mi can heal being directly related to the amount of Haki available to consume, injuries that require more Haki than available are otherwise untreatable.

Furthermore, despite the medical marvels this fruit can perform, it is impossible for Amethyst to bring another person back to life. Why this is the case is unknown.

The Kiryo Kiryo no Mi also grants those who eat it with standard Devil Fruit weaknesses.
