Konoha Muramasa

A classmate of Haruaki, this non-human entity possesses the unique ability to transform into a sentient blade. As a "cursed tool" forged from centuries of agony and resentment, she shares a similar origin with Fear. Her sword form carries a dangerous drawback, as the wielder feels every wound inflicted upon their enemy. Through her "Killing Counter" ability, she can pinpoint and shatter an opponent's weapon, though she must endure the playful, insulting nicknames bestowed upon her by Fear.
