Kokushibo

The eldest son, Michikatsu, grew up as the family heir and lived in luxury, while Yoriichi was considered cursed by a strange birthmark on his forehead. His brother lived in a cramped room and ate poor food, preparing to be sent to the temple at the age of ten. Michikatsu pitied his "weak" brother, who constantly clung to his mother's clothes. He even gave him a homemade bamboo flute so he could "call for help." During training with a fencing instructor, Yoriichi, who had never held a sword before, instantly defeated the master. This shocked Michikatsu and engendered a burning envy of his brother's innate talent.

In its final form, the sword lengthens significantly, resembling a forked scythe or a bizarre tree-like blade. Because the sword is part of the demon's body, it instantly regenerates if damaged. The eyes on the sword allow Kokushibo to see enemy attacks from different angles, which, combined with his three pairs of eyes, makes him virtually invulnerable in close combat.

A tall, muscular demon (male), he has long, thick black hair with red tips, pulled into a high ponytail. He has six eyes, but three Naras on each side in a column. His eyes have red sclerae with straight cracks and yellow irises. In the two central eyes are the kanji for "one" and "supreme." Above him is a flame-shaped mark on the side of his forehead, and on the opposite side is a similar red mark in the corner of his jaw. He wears a purple kimono with a black pentagonal pattern, black hakama pants in the Umanori style, a white obi belt, white socks, and zori sandals with purple straps.
