Great Demon Whirlwind

The Great Demon Whirlwind (大魔旋風 Daimasenpū) is a form of Axemanship that's utilized solely by Marine Captain Gambi Marlow. The style itself was inspired by the Great Demon Fist which was created by Marine Instructor Bambina. Interestingly, due to the Great Demon Fist being inspired by the Horn Hidden Fist, the Great Demon Whirlwind strongly resembles an axe wielding variant of the ancient Oni fighting style.

Overview
Much like the Horn Hidden Fist, the Great Demon Whirlwind emphasizes on using one's great resilience to physical damage to outlast and opponent and deliver damage without having to avoid strikes too often. Unlike the Horn Hidden Fist however, the Great Demon Whirlwind is also heavily reliant on emotion, or more specifically, anger to outlast and overpower all whom are unlucky enough to bare witness to this style.

As mentioned before, the Great Demon Whirlwind heavily emphasizes on controlling one's anger. Marlow himself describes it as "channeling your anger through the axe itself" as by doing so, one builds up the power they are able to unleash. For this reason, Marlow may also allow himself to get struck, not only to reveal an opening in his opponent, but the pain, although often being minimal due to his natural resilience as an Oni, causes the next attack he performs to be more powerful than the next. Marlow himself described it as "building up your rage" so in a way, the more severe hits Marlow takes in battle, the stronger his attacks become as a result.

Marlow considers emotion a powerful thing, as while it can increase one's ability to cause damage, it also causes one to be able to ignore pain as the sense of emotion overrides one's ability to feel injury. This makes the Great Demon Whirlwind, not only capable of causing massive amounts of damage, but due to an Oni's natural resilience and the harnessing of one's emotions to shrug off damage, the Great Demon Whirlwind isn't to be trifled with.
