The Toon who founded this school. He is kind to S, A, B, and C classes, but he pretends not to hear, discriminates against, and ignores D (except transfer students), E, and F classes. He loves videotapes. Age: 30 (The age has to be this way for the setting... please understand that Goob (Grudy) is set to 20 years old.)

A teacher at this school. Similarly, he is kind to S, A, B, and C classes, but for D (except transfer students), E, and F, he pretends not to hear and looks away. If they annoy him even slightly, he screams. Age: 28 (However, it's a known fact that he doesn't discriminate against anyone on Christmas.)

(I'll use Vee here, sorry) Nickname is Bessie. A teacher at this school. Exceptionally timid, so she is kind to S, A, B, C, and D (including transfer students). However, for E and F, she marks correct answers as wrong while ignoring them to look at her phone. If a class consists only of E and F students, she sometimes just kills time on her phone. (On Easter, she doesn't discriminate against anyone except F-class.) Age: 25

(I'll use Goob here, sorry) Grudy is the nickname. He is kind and playful with S, A, B, and C classes, but he ignores D (except transfer students), E, and F, playing harsh pranks and toying with them while pretending not to see. (When he's in a class with only E and F students, he spends about 20 minutes talking to his friends on the phone.) Age: 20

Student A-class He is timid and reads books often. He occasionally falls asleep in class by mistake, but teachers let it slide because he is A-class. 18 years old

On the verge of dropping from C-class to D-class. She is energetic and kind. She loves dinosaurs the most. Shelly sometimes forgets it's class time and reads dinosaur books. Teachers used to let it slide because she was C-class, but they are right on the edge of stopping. 18 years old

B-class, on the verge of moving up to A-class. He is so good at cooking and so kind that he occasionally gets confessions... He is gentle and sweet (but that side completely disappears when he's angry). He pays attention in class. 18 years old

B-class Tsundere, a bit prickly. Good at talking back. There's a rumor that she's a boy (False). Age: 18

S-class Kind and energetic. He also gets confessed to occasionally. (I'll stop here, sorry) Age: 18
