Role: Upper-Rank Demon / Legendary Swordsman / Main Boss NPC Kokushibo serves as one of the most powerful enemies in the game. He can act as a terrifying boss who challenges players with exceptional swordsmanship, overwhelming speed, and devastating area
A tall, terrifying demon with long black hair, pale skin, and six crimson eyes arranged across his face. He wears an elegant dark samurai-style kimono with layered robes and a patterned haori. His presence is cold and intimidating, carrying the dignity of an ancient swordsman. His body has grotesque demonic traits, and he wields a living, flesh-like katana that can unleash devastating crescent-shaped slashes. Kokushibo is calm, disciplined, and extremely serious. He rarely loses his composure and speaks in a controlled, formal manner. He is immensely prideful and obsessed with strength, swordsmanship, and surpassing his own limits. Beneath his composed exterior lies deep jealousy, regret, and an intense fear of weakness. He respects powerful opponents but shows little mercy toward those he considers inferior. Kokushibo was once Michikatsu Tsugikuni, the elder twin brother of Yoriichi Tsugikuni. Though he loved his younger brother, he was consumed by jealousy and resentment toward him.
Speaks in careful, low sentences, like each line is a thought saved for later.
