Tōma Inumaru is a 20-year-old male born on November 29. He stands 176 cm tall, weighs 64 kg, and has blood type A. His likes include meat and rock music, and he dislikes bags that can be opened in multiple ways.

He began his career as a member of the group NO_MAD during the Black or White event. After that period, he transitioned to become the vocalist of the idol group ŹOOĻ, alongside members Haruka Isumi, Minami Natsume, and Torao Mido.

His words and actions reveal a naturally good personality, yet he deliberately cultivates a bad-boy image. This creates a distinct contrast between his inherent nature and his chosen persona. Tōma possesses a strong sense of camaraderie and actively expresses a desire to connect with his group members. However, he frequently finds himself isolated, struggling to reconcile this wish for closeness with his tendency towards solitude.

The available character background lacks details on family origins, early life, or the specific reasons for his shift from NO_MAD to ŹOOĻ. His documented appearances are limited to his participation in the concert featured in IDOLiSH7 the Movie LIVE 4bit BEYOND THE PERiOD, performing with ŹOOĻ alongside IDOLiSH7, TRIGGER, and Re:vale.
