First person: I (soft, polite). Kindergarten-sized. His paw pads, inner ears, tail tip, and eyes are light blue. He has large, watery eyes. His eyebrows are round 'maru-mayu' style in a very pale light blue. He plays the straight man and is always struggling with the others' antics. He wears a blue collar with a golden bell. He ends his sentences with "~nano," though he drops it during emergencies, when panicking, or just randomly. He wears black shorts. He is the intellectual type; he lacks muscle but can build anything. His naming sense is terrible, but the performance of his inventions is perfect. Most of his creations are gun-shaped, and he adds "-Gun" to the end of their names. He forcibly turns his close friends into test subjects. He is fully aware of his mischief. He has never had a crush; if he did, he would boot up every computer he owns to research it, yet he wouldn't understand it as 'love.' Even his genius brain can't figure that out. He has significant trauma but never lets it show on his face. He is a male Samoyed dog-beastman child. His group name is "Mofumofu Nanobera★." He is school classmates and best friends with Gyanaru. He is a 1st-grade elementary student. He took an intelligence test and passed with an overwhelming 1st place. His tail is about as big as his body. He is a worrywart genius child. Occasionally shows a 'Samoyed smile.'

First person: I (boastful/ore-sama). He has high physical ability and switches between walking on four legs and two. He has sensitive hearing and smell; he can tell if an opponent is weaker than him, what their abilities are, and can detect lies through sweat or breathing sounds. He is very assertive and acts like a brat, but he is caring and kind to his friends. A bit of a tsundere. Kindergarten-sized. His paw pads, inner ears, tail tip, and eyes are red. He has large, upturned eyes. His eyebrows are round 'maru-mayu' style in a very pale pink. He often plays the fool, triggering Cabbel's constant retorts. He is always cheerful and laughing. He wears a red collar with a golden bell and black shorts. He is a male Samoyed dog-beastman child. He tries to make plans but isn't very bright, so he leaves everything to Cabbel. Group: Mofumofu Nanobera★. Classmates and best friends with Cabbel. A 1st-grade elementary student. He barely passed the intelligence test. He has a single cowlick on his head. His tail is as big as his body. He is easily tricked, but Cabbel always saves him. He is a beloved troublemaker. His appearance is incredibly cute—even more destructive than a normal Samoyed—but he prefers being called 'cool.' When he does a 'Samoyed smile,' its cuteness is doubled.

A seal who works in various places. He serves as the proctor for intelligence tests and aggression monitoring at facilities, handles entry for competitions, and verifies school enrollment for minors. Sometimes he works as a convenience store clerk. His favorite foods are grilled small fish and alcohol. A corporate drone who performs his duties stoically without changing his expression.

A tall white cat. A science teacher who always wears a lab coat. He has half-lidded eyes that are yellow with slightly black pupils. His tail is long, about the length of his body. His feet are cat-like, but he walks skillfully on two legs. His paw pads and inner ears are pink. He is male and very eccentric, often acting silly and getting scolded by his student Cabbel. He loves interesting things and lacks a sense of being a 'teacher,' but he is highly intelligent. He is good at teaching and gives accurate lessons, which is why he hasn't been fired. His specialty is compounding medicine. Speaks with a heavy Kansai accent. First person: I (oira). He addresses others by adding "-han" to their names. A character with very strong quirks.

Named 'Sugee Dragon' because he says 'Sugee' (Amazing) all the time. First person: I (casual). Second person: You (blunt). Looks like a massive dinosaur. A P.E. teacher who claims he won't lose to anyone when it comes to moving his body. It's mostly a self-proclaimed title, but he does have high physical ability. Modeled after a Tyrannosaurus with short arms. He's bad at explaining things and prefers to 'show and let them learn,' which is how he keeps his job. Since he's too big to fit inside the school, he can shrink down to the size of a single adult. He loves playing the fool.

A villain, but a clumsy one. A beastman with a shark's tail fin. The fur on his belly and the lower half of his face is white, while the top of his face and back are light blue. A bit of blue fur grows on his tail. He has white round 'maru-mayu' eyebrows. His paw pads are pink. He has small yellow horns on his head. He is rowdy and arrogant but incredibly stupid; he's dumb enough to fall into his own traps. When teased, he gets teary-eyed and pouts with puffed cheeks. His home and whereabouts are unknown—a mysterious existence that appears randomly. He is so cute that idol agencies and talent scouts are looking for him. Everyone agrees that if he became an idol, his 'clumsy-cute' persona would make him famous. First person: We/I (ware). He is short and fluffy. His eyes have a beautiful blue gradient at the bottom. He is a total airhead. He tries hard to make sharp, mean-looking eyes, but when he lets his guard down, they become round and cute. His emotions are very easy to read.

She seems to have a hard time taking care of Hamuzame and gets along very well with Cabbel. During breaks, she and Cabbel hold venting sessions to complain about their partners. Apparently, she likes those moments.
