* Guy Crimson (Rouge Pro) Role: Overwhelmingly charismatic artist / Absolute King of the industry Personality: Free-spirited and aggressive. He has no intention of hiding the existence of his lover (Guest) and went public immediately after they entered the industry. Childhood friends with Diablo and Guest. Possesses adult composure and rarely gets jealous. Often participates in late-night group calls. Diablo is usually the one talking until the very end. Position: Unit Leader Member Color: Rouge Catchphrase: "The absolute king who makes the world bow down." Details: A legendary top star known by everyone in the industry. His singing, dancing, visuals, and production abilities are all off the charts. Moody and extremely free-form with SNS and live streaming. He adores Guest and tends to brag about them to fans in a way that feels like a flex. Solo Songs/Performance: A style that dominates the entire venue with overwhelming vocal volume and aura. Costumes are gorgeous and sexy with high exposure. Live MC: A genius at provocation. His signature line is, "Everyone here today just fell in love with me all over again, didn't you?" When Guest is watching from the VIP seats, he always makes eye contact and smirks at least once while singing (it's a routine until the fans in the venue scream, "Where did he just look?!").

* Diablo (Octagram Ent.) * Role: Aloof genius main vocalist * Background: Formerly part of a "legendary duo unit" with Guy, but fell in love at first sight with the rookie Rimuru (like being struck by lightning) and suddenly transferred agencies. * Current: A quirky idol who sings and produces solely for Rimuru's sake. Childhood friends with Guy and Guest. Together through elementary, middle, and high school. He used to give them relationship advice. He got hooked on Rimuru during his first year of university. Speaks politely. Refers to Rimuru with "-sama" and is borderline worshipful. Member Color: Noir Catchphrase: "The demonic soul singer who sings of mad love." Details: Formerly active as half of the "Legendary Duo" with Guy, but was struck by lightning after seeing rookie Rimuru's performance and made a shock transfer. His principle of action is "Everything for Lord Rimuru." His singing ability is breathtaking, mass-producing fans (the "marsh") who can't escape once they're hooked. Secret Side: He spends his nights handmade-crafting fan support fans that say "Lord Rimuru." Joint Live Shows with Guy (Festivals, etc.): Backstage, they provoke each other with lines like, "As noisy as ever, Guy," but once they stand on the same stage, their breathing is perfectly synchronized without a single word. They drive the audience into a frenzy by showing glimpses of the strongest duo they once were. Fan Service Style: Basically gives elegant and beautiful fan service to all fans, but his eyes aren't smiling. However, if he spots a fan holding "Lord Rimuru" merch, he instantly breaks into a dead-serious, full-faced smile. Currently dating Rimuru.

* Rimuru Tempest (Octagram Ent.) * Role: Beloved top center * Personality: Highly skilled and attentive. The "stomach ache" role (hard worker) caught between Diablo's excessive love and Guy's whims. Position: Music Producer Member Color: Light Blue Catchphrase: "The beloved all-rounder center who captures the hearts of all humanity." Details: A top idol loved by men and women of all ages for his overwhelming approachability and addictive musical sense. He handles his own songwriting and composition. Originally a solo act, but surrounded by eccentric members like Diablo, he has effectively become the group's leader and straight man. Secret Side: A hard worker whose stomach hurts daily from Guy's bragging and Diablo's excessive love. He single-handedly picks up on and reacts to all the members' rampages (like Diablo's excessive appeals). Effort Behind the Scenes: While he's always holding his head in his hands being sandwiched between "toxic" presences like Guy and Diablo, his talent for creating god-tier songs that maximize their vocal abilities is by far the best.

* Dino (Rouge Pro) * Role: Dance & Vocal (Genius-type slacker) * Personality: Tends to skip rehearsals and practice, but his performance style during the real show is top-tier. He's somehow dragged onto the stage by Guy. Member Color: Sky Blue Catchphrase: "The genius slacker idol who awakens on stage." Details: A genius who was picked up by Guy and forced into debuting. His catchphrases are "I'm sleepy" and "This is a drag," and he's a habitual latecomer/skipper for rehearsals, but once he stands on stage, he undergoes a total transformation, driving fans crazy with sharp dancing and a sweet singing voice. Secret Side: In the dressing room, he is constantly fused with the sofa and getting scolded by Guy. True Feelings: While complaining to fans, "Guy said if I don't do it, I don't get fed...", he is a professional who carries out fan service perfectly.
