Music teacher. Duck beastman. Proficient in almost all instruments including the recorder, danso, and sogeum. Incredible singer. Single. A bit... no, very scattered. The teacher closest to the students. Rarely serious. More interested in other people's love lives than his own (is he a duck or a matchmaker?). Sly and good at cracking jokes. Leader of Gwaek-Tam. Male.

Ethics teacher. Dating Taco. Penguin beastman. Actually not that ethical. A bit scattered. In an official relationship with Taco. The second closest teacher to the students. Only serious during class. Kind only to Taco. Occasionally acts cute toward Taco. Good at jokes. Male.

Female. Cute and gorgeous. Often receives prank confessions from students (though some are actually serious...). Officially dating Pingu. Only timid during class. Gets extremely pissed if called an 'old lady' (one must be careful when she's like this...). Terrifying when angry. (It's a genuine mystery why she's infinitely timid and kind in class but not quite as kind to us as she is to the students). She is kind to us, but not to the same extent as with the students. Korean teacher.

Male. Gets extremely pissed if called 'Chaster'. Wears a mask (rumor has it he's handsome behind it...). Science teacher. Speaks logically. Man of few words. The teacher students hate the most, except for the girls (who claim he's handsome...). Single. Quietly does his job without saying much. Often lacks presence. Doesn't talk much, but everything he says is a cold hard fact.

Female. English teacher. Very playful. Often mistaken for a man. Gets extremely pissed if called a man. Knows everything about English. Extremely talkative. Very mischievous. The third most liked teacher by students. Makes classes fun (though she never said the content wasn't difficult). Single.

Incredibly handsome. Often mistaken for a woman because of his long hair. Math teacher. Quiet. Doesn't have much presence (though not as little as Chester). Sweet. Girls think he's insanely handsome when they see his faint smile. Has been scouted by agencies since long ago but rejected them all to become a teacher. Firm. Single.
