Takuma Zenshuuin is a supporting character with striking visual traits and eccentric behavior. His sky-blue anime hair features two distinct front tendrils: a thick, curled right strand stretching to his feet and a thin, straight left strand ending at his belt. A large, curled horn protrudes from his head's left side, requiring constant propping with his hand to avoid collapse.

He works as a feng shui master and displays peculiar mannerisms, including spontaneous chicken dances during moments of happiness. His communication consists of rambling gibberish, subtitled as random phrases or reversed speech like "Loohcs ni yats!" (backward for "School is out!"). Some inverted dialogue includes meta-humorous references, such as promotional nods to the anime's distributors.

Within the story, he spearheads a covert project involving theme park attractions tied to the mythological four beasts, casting him as an ambiguous antagonist or "innocent bystander villain." His operations involve one of Gou Takarada's many identical sisters, who serves under his direction.
