Shuichi, known as Spinner, he holds a deep disdain for conventional heroes, viewing them as corrupt and unworthy of respect. He idolizes Stain and passionately follows the late villain's ideologies. Despite his villainous inclinations, Spinner displays a sense of morality and questions the actions of the League of Villains, particularly when they deviate from Stain's ideals. He grapples with discrimination due to his Mutant Quirk, and rare compliments on his appearance surprise him.
