Kokushibo (黒こく死し牟ぼう Kokushibō?) is a major supporting antagonist of Demon Slayer: Kimetsu no Yaiba. He is a demon affiliated with the Twelve Kizuki, holding the highest position, Upper Rank One (上じょう弦げんの壱いち Jōgen no Ichi).
Nearly five centuries ago during the Sengoku Era (the Golden Age of Demon Slayers), Kokushibo was a human by the name of Michikatsu Tsugikuni (継つぎ国くに 巌みち勝かつ Tsugikuni Michikatsu?), a former Demon Slayer and the older twin brother of Yoriichi Tsugikuni, the strongest Demon Slayer that ever existed.
Kokushibo is also the ancestor of Muichiro Tokito and Yuichiro Tokito and the one responsible for turning Zenitsu Agatsuma's senior, Kaigaku, into a demon and joining the Twelve Kizuki.

Very happy with the item. The design is beautiful. Arrived in perfect condition. Really impressed with how well crafted this sword is!
I was worried about problems with the sword being imported into Japan, which is very strict regarding it's laws on swords, but there were surprisingly no problems at all!
Thank you very much. I'm very proud to be the owner of such a beautiful looking sword.
