Gyomei Himejima is a major supporting character of Demon Slayer: Kimetsu no Yaiba. He is a Demon Slayer of the Demon Slayer Corps and the current Stone Hashira. Gyomei also serves as the mentor of Genya Shinazugawa.

Fighting Style

Kusarigamajutsu: Unlike ordinary Demon Slayers who use swords in combat, Gyomei uses a spiked flail and axe reminiscent of a Kusarigama, a weapon consisting of a scythe and heavy iron weight connected with a metal chain, and thus would use a similar fighting style known as Kusarigamajutsu. As a Hashira, Gyomei is extremely proficient in combat and one of the most skilled combatants in the entire Demon Slayer Corps, particularly in this fighting style which can briefly match the likes of Upper Rank One, Kokushibo, a demon swordsman who has over 4 centuries of swordsmanship experience. Moreover, he was also shown to be able to hold off Muzan and his blisteringly fast whips for an extended period of time, using his spiked flail to deliver powerful blows to the Demon King.

Breathing Style

Stone Breathing: A Breathing Style Gyomei either mastered himself or learned from a cultivator. In his own version of this Breathing Style, Gyomei incorporates his superhuman sense of hearing and physical strength to utilize a spiked flail and axe to use its techniques. As the Stone Hashira, Gyomei is his generation's most skilled Stone Breathing user. He displayed mastery of Stone Breathing in his battle against Kokushibo, where he was able to unleash attacks that were able to match the demon's Moon Breathing.

Techniques

• First Form: Serpentinite Bipolar - The user throws both the flail and axe towards their intended target and manipulates the chain by rotating it thus causing the axe and flail to also rotate in order to drill and grind right through their target.
• Second Form: Upper Smash - The user throws both their axe and spiked flail for a pincer move before smashing down on the chain to cause the flail to then rebound and smash his target from afar.
• Third Form: Stone Skin - The user unleashes a series of slashes with their axe deflecting nearby attacks.
• Fourth Form: Volcanic Rock, Rapid Conquest - The user manipulates both the flail and axe weapons at both ends of the chain by swinging the chain on both sides in order to strike their opponent using a two pronged wide ranged attack.
• Fifth Form: Arcs of Justice - The user utilizes a powerful barrage with their flail and axe, doing a great amount of damage. The axe is destined to hit first with the trajectory of the flail following from the opposite side and slamming into the opponent.

Nichirin Chained Spiked Flail and Axe: Gyomei wields a swinging/whipping weapon similar to a Kusarigama, consisting of an Ono (axe) attached to a Chigiriki (flail) via a long chain. Still, the weapon was forged from the same materials used in the creation of Nichirin Swords. Its craftsmanship in particular is noted for being incredibly high-class, and even superior to the swords forged during the Sengoku period, when swordsmithing was at the peak of development. Even Upper Rank One, Kokushibo, could not cut through the chain and was forced to instead resort to long-range combat. As noted by Kokushibo, this weapon is very well thought out, as the echoes created by the chain can be picked up by Gyomei's acute sense of hearing to accurately grasp the space and movements around him, further enhancing its effectiveness in battle. On the hilt of his axe, the words Destroyer of Demons are carved.
