Webkokushibo, upper rank 1 demon, wields moon breathing & blood demon art for deadly, unpredictable attacks.
Kokushibo combines swordsmanship with blood.
Webkokushibo’s eyes harbor a curse known as the curse of eternal bloodlust.
This curse grants him an insatiable hunger for battle, driving him to seek conflict and bloodshed.
Webkokushibo is the only demon that falls second to muzan, so he carries the most brute strength, as he is currently the demon that carries most of muzan’s blood.
