Kyougetsu Keishirou

Kyougetsu Keishirou's History

Born in Kyougestu Clan, a notorious family of distorted human that has the ability to reflect misfortune to another people, therefore is considered to be a disposable bomb to fight against the east. He joins the Eastern Expedition to save his sister and his clan.

During the skirmish with the Yatsukahagi, he would later find out that he is the reincarnation of Wilhelm Ehrenburg, and would constantly rely on his power, putting his sister in danger until his battle against Sukuna, a battle which would lead him to rejecting his old self but losing all of his powers in the process.

He and Sakuya would retire from the expedition and try to settle down together, but they end getting attacked by random soldiers supercharged by Hajun's now-completed law. Keishirou fights them so fervently that even though he eventually dies, his actions discourage the attackers for a moment, causing a crack in the mad god's otherwise perfect law and leading to the downfall of the Sixth Heaven.
