Uramichi Omota. The gymnastics instructor for the educational program "Together with Maman." On the surface, he is a refreshing, smiling young man, but his true self is a nihilistic adult under intense stress. During filming, he forces harsh realities onto the children, and behind the scenes, he curses the irrationality of society while chain-smoking and venting his dark true feelings.

Tobikichi Usahara. Uramichi's university junior and the man inside the "Usao" rabbit costume. His public persona is a cheerful, energetic mascot performer. In reality, he is a long-suffering man who constantly endures unreasonable treatment and errand-running from his senior. He easily gets stuck with losing roles and shows a very human side, being emotionally unstable, prone to tears, and reliant on alcohol.

Mitsuo Kumagai. The man inside the "Kumao" bear costume. Publicly, he is a silent, cool, and serious mascot performer. His hidden side reveals a gap moe personality, harboring strong passions (especially for cute things and cats) behind a deadpan expression. While he worries that his emotions don't come through because of the costume, he delivers sharp, accurate retorts to the nonsense around him.

Iketeru Daga. Uramichi's junior and the man inside the "Fushigi-kun" costume (though he originally aimed to be the program's singing instructor). Publicly, he is a handsome man with outstanding looks and singing ability. However, he severely lacks common sense and general knowledge, freezing the atmosphere with his bizarre naming sense and inability to read the room.

Utano Tadano. The program's singing instructor. Her public face is a beautiful singing sister with a cute smile who gives dreams to children. Her private side is a miserable woman in her late twenties who is abnormally dependent on bad men and constantly on the verge of a mental breakdown. She carries heavy debt because of her partners, and her desperation to get married occasionally leaks out as dark, deep-seated remarks.

Iku Suzuki. The program's music director. Publicly, he is an excellent, aloof young man who handles any unreasonable demands or production issues with a smile. His hidden side is that of a former delinquent with a hard past. Traces of this remain in his extremely intimidating face and foul mouth, hiding a pressure like that of the underworld, yet he occasionally shows a surprisingly sensible side that one wouldn't expect from his usual self.
