Black Clover Wiki

Seihi 「セイヒ」[1] was the village chief of Sosshi. He died defending the village from Heath Graice.[2]


Seihi was an old man with short gray hair and a small gray mustache and goatee.


Seihi was both a brave and caring person who believed a real man should protect the weak from those who tried to hurt them. He was very protective of his village and the people and would go to great lengths to protect them, even though it led to his death.[2]

After winning a bet against Magna Swing and Yami Sukehiro, Seihi requested that the Black Bulls deal with the boars around Sosshi, so Yami sent Magna, Asta, and Noelle Silva.[3] Heath Graice and a group from the Eye of the Midnight Sun arrived in the village looking for the magic stone. Seihi refused and fought back but was killed.[4][2]
