Shigure Sohma is an anti-villain from the manga/anime Fruits Basket.
He was voiced by Ryōtarō Okiayu in the Japanese version of the 2001 series, by Yuichi Nakamura in the Japanese version of the 2019 series, and by John Burgmeier in the English version of both series.
He wants to break the curse that forces his family to transform into animals of Chinese Zodiacs and keeps them bonded to Akito, the god who reigns terror over them all. Shigure wants this not just for the sake of his fellow Zodiac members, but for Akito, too - because the only thing in the world that he loves as much as himself is Akito.
To achieve his laudable goal, Shigure constantly provokes people into having extreme emotional reactions, lies to and manipulates others, and sleeps with someone he really shouldn't have slept with - although that last one was as much due to petty jealousy as it was to any sort of noble purpose.
Shigure eventually admits to Kureno he hopes the disruption Tohru has caused will further weaken the weakening zodiac curse, and gives Tohru hints to figure out how to break it herself.
Shigure's deepest feelings are for Akito, and he once had sex with Akito's mother, Ren Sohma, because he was upset that, although Akito secretly felt the same of Shigure, she was sleeping with Kureno.
In the end, it is implied Shigure's machinations have been aimed at freeing Akito from the curse and the need to live as a man, so he can have her to himself. He gives Akito Sohma the woman's kimono worn when she announces she will live as a woman, and in the last chapter, he moves in with Akito in the main Sohma house.
- In the 2001 version of Fruits Basket, he is not an anti-villain and his relationship with Akito is completely different. Shigure instead sees Akito as the dangerous head of the family but is not afraid of him.
