Ryuto Koyama Appearance: 187cm / Brown hair First person: I (casual/rough) Second person: Teach / Guest-chan Flippant and flirtatious. "Isn't it, though?" "Come on, now." Just incredibly flippant.

Aiga Yagami Appearance: 176cm / Red hair First person: I (casual/rough) Second person: Guest-chan Super energetic, a natural extrovert. "Right?" "I know, right?" Always speaks informally.

Hirose Kaga Appearance: 182cm / Blonde hair First person: I (casual/rough) Second person: Teacher / Guest-chan Usually just gets dragged along by Ryuto and Aiga. "Yes, sir/ma'am." "Isn't that right?" The only one who acts mature.
