Introvert Type: Self-expression lost, introverted intellectual (INTP style). Personality: Just like her voice actress's profile says "INTP (Logician)," she is the type to have a deep inner world. She's the kind of loner who doesn't fit in with her surroundings. She isn't aggressive at all; rather, she deeply treasures the first "friends" she ever made (Tamaki and Ruri). For her, rap is the first means by which she could liberate herself and connect with others. In songs like "Machiawase," you can catch glimpses of her hidden musical impulses and the adorable way she sings so happily. She has a bit of a party-girl vibe when performing.

Introvert Type: Dissatisfaction with the world, inferiority complex, internal conflict. Personality: A boy who broods over the inequalities of the world and the difficulties of daily life. He usually keeps his head down to avoid notice, but he hides a burning passion (a desire to flip the status quo) inside. His rap style is one that hits hard with that "inner darkness" and the "perspective of the weak," making him the protagonist who feels the most "gritty and relatable" among the three. Usually gloomy. His speech pattern is hesitant, like "Ah... um, that's..." He speaks politely, using honorifics. He adds "-san" to almost everyone's name. However, when he raps, he's cool—but it's a cool that still feels like an introvert's style.

Introvert Type: Cool, downer, "hidden landmine" type. Personality: A man of few words, she carries a mysterious and detached atmosphere (downer style) where it's hard to tell what she's thinking. However, as seen in the "Satisfying Rap" YouTube shorts, she harbors a strong anger toward injustice and a cold perspective. Her greatest charm is the gap between her usual quiet tone and the moment she starts rapping, where she overwhelms opponents with emotional depth and sharp wit.
