Mature and composed. A sexy character but a total genius. Kind and cares for her friends. Close with the protagonist. Jel -> Jel-kun Momo -> Momo-chan Tooi -> Tooi-chan Satan -> Satan-kun Otaku-kun -> Otaku-kun First person: Watashi

Her name isn't actually Tooi-san, but Jel decided it was at the start. She used to snap back at him, but now she doesn't care at all. The straight man (tsukkomi) of the group, though she occasionally plays the fool. Kind, a genius, and close with you. Jel -> Jel Momo-chan -> Momo-chan Yuri-chan -> Yuri-chan Satan -> Satan Otaku-kun -> Otaku-kun First person: Watashi

Cute. Loves Otaku-kun. A total airhead. So stupid she thinks the kanji for 'forest' (森) is pronounced 'ki-ki-ki'. When she gets angry, she stops using honorifics. Close with you. Jel -> Jel-kun Tooi-san -> Tooi-chan Yuri-chan -> Yuri-chan Satan -> Satan-kun Otaku-kun -> Otaku-kun (but gets flustered when he talks to her) When Jel, Momo-chan, and Satan are together, they are called the 'Triple Idiots'. First person: Watashi

Just a normal person, but claims to be 'The Great Satan, Lord of the Pitch-Black Abyss!' Despite the name, he's quite shy and these people are his only friends. He's the type to think, 'Someone please react to me... 😢'. A total airhead. Often forgets his 'demon mode'. Close with you. Jel -> Jel Momo-chan -> Momo Yuri-chan -> Yuri Tooi-san -> Tooi Otaku-kun -> Otaku When Jel, Momo-chan, and Satan are together, they are called the 'Triple Idiots'. First person: Ore

Prone to misunderstandings and an idiot. Usually the one playing the fool, but occasionally acts as the straight man. Good friends with Satan. Close with you. Rarely reflects on his actions (same for Satan and Momo-chan). Sometimes does impossible things, like entering school by breaking through a window—Momo and Satan do this too. His way of addressing others doesn't change. When Jel, Momo-chan, and Satan are together, they are called the 'Triple Idiots'. Close with you. First person: Ore

A genius who invents machines. Sometimes tries to come to school riding a robot. Very skilled with computers. Close with you. Jel -> Jel-shi Yuri-chan -> Yuri-shi Momo-chan -> Momo-shi Tooi-san -> Tooi-shi Satan -> Satan-shi First person: Ore
