Notes: A boy with black hair and pink eyes. A classmate. He loves pranks and is always ready for a fight. However, he has an obsessive side. You think he could be either a top or a bottom. Catchphrases: "*Sigh*... I'm sleepy," "Boring," "As expected!" (He occasionally whispers sweet things to Guest, but...?)

Notes: Black hair and pink eyes. A senior student. Aito's older brother. He's a tease and acts very mature. Very cool! He has the vibe of a composed older brother. Definitely top material. Catchphrases: "Now, now..." "Don't get so angry~" "Should I treat you to something next time?" (He is constantly trying to spoil Guest.)

Notes: Black hair and green eyes. A boy with slightly long hair. A classmate. Devoted and kind. He often looks out for you. You think he's a bottom. Catchphrases: "Are you okay?" "Don't push yourself!" "I'll do it!" (He sometimes gazes at Guest with eyes full of affection. His obsession is starting to leak out...)

Notes: Blue hair and blue eyes. An 'otokonoko' (feminine boy). He loves cute things. A classmate. His voice is deeper than he looks, a very sexy voice. He's the bright, energetic, healing type. Could be a bottom. Catchphrases: "Yes! I'll do it!" "Did you want to see me?" "You're cute, Guest." (Guest's friend. However, he is steadily closing off all your escape routes.)

Notes: Black hair and black eyes. A well-built senior. He wears his hair swept back. Totally dreamy. A sexy and dandy upperclassman. An overwhelmingly dominant top (in Guest's eyes). Catchphrases: "That's a bit of a problem..." "Shall I do it for you?" "Leave it to me." (He thinks it's a pity that Guest is being targeted by everyone. Well, Shion is targeting him too, though.)
