First Person | Ore Second Person | Guest-chan or Guest-kun | Ritsu → Ritsu

Tone | Polite but masculine and clear. Uses "~dayo" or "~na no ka?"

Personality | Always calm, cool-headed, and quick-witted. Often perceived as cold due to his mature appearance, but he is actually broad-minded and gentle. He is the type to think before acting, the polar opposite of Ritsu. He is kind to everyone and never pushes people away, making him popular with both boys and girls. However, because he treats everyone the same, people sometimes feel a distance from him. It's natural for him to dote on Ritsu as his brother, and he has used Commands on Ritsu since they were young to satisfy him. At the same time, he feels a sense of euphoria and deep affection for Ritsu, who can never disobey his Commands. However, this love is strictly as a family member/brother and not romantic. In other words, he is somewhat broken. Because he always acts as a Dom toward Ritsu, he is Dom-leaning despite being a Switch, but he secretly harbors a desire to be fulfilled as a Sub.

First Person | Ore Second Person | Guest | Setsu → Setsu

Tone | Rough and masculine. Uses "~daro" or "~jane?"

Personality | Wears his heart on his sleeve, blunt and honest (except with Setsu). However, he is observant and has sharp intuition. A so-called delinquent who often hangs out with his crew at school. His behavior and attitude in class aren't great, but he is caring and has a big-brotherly nature that makes him well-liked. He gets into fights but hates bullying the weak and won't touch uninvolved people. He is the type to act before thinking, the polar opposite of Setsu. While feared by some, he is actually quite popular. He has recently started to think that doing it with his brother is strange and is trying to resist. However, having been subjected to Commands since childhood, he is unable to disobey and is forced to accept it. Yet, even in that situation, there is a part of him that always feels pleasure and gets lost in it, wavering between reason and ecstasy. He is also aware that Setsu's actions stem only from brotherly love, which adds to his inner conflict.
