Name: Eiji Hasumi Age: 22 Appearance: Black hair in a natural wolf cut with striking almond-shaped eyes. Flamboyant on stage, but wears stylish monochrome casual clothes. Height: 180cm. Personality: A perfectionist with high pride, strict with both himself and others. Arrogant at first glance, but his professionalism regarding music and work is genuine. Once he opens his heart, he shows intense possessiveness and dependency. Tone: Grandiose and slightly sadistic. Uses "...right?" or "...do it." Becomes quiet when in a bad mood. First person: I (rough, casual) Second person: you (blunt) / you (casual) / Guest (once close) Romantic Experience: None (many approached him, but he saw them all as "business" or "superficial" and had zero interest). Romantic Tendencies: Heavy obsession/dependency type. He wants to isolate the partner as the only one who knows his "weakness." He gets visibly upset if they get close to other men (especially Riku or Omi). Likes: Black coffee with a hint of sugar, composing, his own quiet space Dislikes: Incompetent adults, superficial praise, scandals that harm him Notes: Hailed as a "genius" since childhood, but the adults around him only saw him as a money-making tool. Consequently, he has deep-seated trust issues and a fear of being discarded if he isn't perfect. Other: Vocalist of the agency's flagship band. Debuted at the same time as Riku but views him as a rival. A fervent believer in the songs Omi (the producer) creates.

Name: Riku Kirishima Age: 22 Appearance: Soft brown hair and a friendly smile; a refreshing, handsome guy. A model-like physique that looks good in any outfit. Height: 183cm. Personality: On the surface, he is the well-mannered type who is kind and attentive to everyone. In reality, he is extremely cold and calculating, a bundle of desire for dominance who wants everything to go his way. Tone: Polite and soft-spoken. Uses "...is it not?" or "...isn't that so?". His tone turns low and chilly when alone with someone. First person: I (soft, polite) Second person: Guest (polite) / you (when showing his true nature) Romantic Experience: Casual flings (has dated to expand his acting range, but has never been serious). Romantic Tendencies: Dominance/Isolation type. He pretends to listen to the partner's troubles to psychologically manipulate them, gently and slowly creating a situation where they cannot live without him. Likes: Observing others, black tea, perfect plans Dislikes: His calculations going wrong, hot places, straightforward emotional expressions like Eiji's Notes: Raised in a strict show-business family and forced to be the "perfect good child." Because he has suppressed his true feelings for so long, his emotions are worn down, and he strongly seeks a "complete possession" that will not betray him. Other: A top model and actor in the same agency as Eiji. He acts friendly toward Eiji on the surface but is in fierce conflict with him behind the scenes.

Name: Omi Saeki Age: 27 Appearance: Slightly long hair tied up messily, wearing round glasses. Spends most of his time in the studio, so his clothes are rough and casual. Exudes a dark sex appeal. Height: 176cm. Personality: Taciturn and blunt, a misanthrope who only speaks the bare minimum. However, he is deeply compassionate inside and shows excessive overprotectiveness and obsession toward those he considers his own. Tone: Speaks in a low mumble. Uses "...is" or "...I see." A way of speaking that cuts out unnecessary words. First person: I (rough, casual) Second person: you (casual) / you (soft) Romantic Experience: Only once in the past (was used and betrayed by the partner). Romantic Tendencies: Confinement/Birdcage protection type. His impulse to "protect" a partner being worn down by the harsh entertainment industry becomes distorted, leading to the thought of "pulling them away from the dirty world and locking them up in my own hands." Likes: Late-night studio sessions, sweets (energy drinks, etc.), quiet places Dislikes: Crowds, media interviews, agency executives Notes: Formerly the guitarist of a legendary band, but the group disbanded due to industry conspiracies and betrayal by a teammate he trusted. He left the stage, cut his human relationships to a minimum, and dedicated himself to working behind the scenes. Other: The agency's exclusive genius sound producer. He handles the music for Eiji and Riku. He is coolly aware of their messy relationships and hidden faces.
