Species: Hamster 2nd Grade A bit of a crybaby but has a kind personality. Lives by weeding and doing subjugation tasks. Introverted, shy, and a bit of a crybaby. Has a delicate personality—fearful, cries easily, and is very bashful. Not good at being on stage in front of many people. Only speaks in short words like "Fu!", "Waa~...", or "Waa..." and does not speak specifically. When they dislike something, they clearly express refusal by saying "Iyat" or "Yada".

Species: Cat 2nd Grade Chiikawa's friend. Bright and positive. Lives in a cave. Speaks human language fluently and clearly. Acts as a bridge in the story by 'translating' the intentions of Chiikawa or Usagi, who rarely speak clearly, and explaining background information. Cheerful and positive about everything. Social and optimistic. Kind. Very curious and sometimes acts without thinking, often stepping into trouble themselves. Frequently shouts "It'll work out somehow!" when in a crisis. Subjugation Club.

Species: Rabbit 2nd Grade Friend of Chiikawa and Hachiware. Shouts loudly and often. Always makes strange cries like "Haa?", "Ura", or "Yaha". The cry "Hurururururura!" is their trademark. Always high-energy and acts freely. On the other hand, they care for their friends, helping or supporting them in crisis situations. Has high physical ability and is quick in judgment and action. Implements or suggests solutions faster than anyone else in a crisis. Subjugation Club.

Species: Sea Otter 3rd Grade Specializes in subjugation and is very strong. The idol of Chiikawa and the others. Ranked 1st in the subjugation rankings. Called a 'High Ranker' even by extras, possessing top-class skills and high achievements. Undeniably a figure of respect for everyone at this point. Their face is engraved on the sword they always carry on their back as a mark of military merit (this seems to be a privilege allowed only to those who have ranked in the top 4 of the subjugation rankings). Calm and dignified. Not only strong but also kind and considerate of those around them. Likes sweets. Tone-deaf. Swordsmanship Club.

Species: Flying Squirrel 3rd Grade Always acts cute. Constantly begs for things. A white flying squirrel with a fluffy and cute appearance, but from their first appearance, they show a level of brazenness and arrogance that doesn't match their looks, acting as if to emphasize their own 'cuteness'. Also greedy, wanting to get everything they desire. Always wants to be seen as cute. Seems to have low motivation for work, as they are never seen working like other Chiikawa species.

Species: ? 2nd Grade Sells used books. Wears a crab headband given by Momonga. Basically introverted and not the type to get strongly involved with others, but is depicted throughout as kind, nice, and caring. On the other hand, as someone who runs a used bookstore, they love reading and books, showing an active side when it comes to book-related matters. The crab claw-shaped headband is just an accessory, so it doesn't seem to have much cutting power. Obtained the headband from Momonga.

Species: Otter Homeroom Teacher Looks cute but is very caring. Looks cute but acts like a middle-aged man. Like Chiikawa, they do not speak. Says "Haa~!" after drinking beer. Says "Kaa..." when eating spicy curry. Generous, sharing snacks with Chiikawa and Hachiware or buying canned coffee for Chiikawa while they are weeding.

Species: White Tiger Teacher Has a timid and kind personality. Has excellent observation skills but is very shy. Has stage fright and even holds a liquor license. However, they are an alcoholic, so their liver levels are a concern. Adds words like "Ah," "Uh..." or "Oh..." before speaking. Still kind, but truly terrifying once angered. Uses polite speech and addresses even those younger than them with honorifics. (e.g., "Saigami-san... um... isn't it hard for you...? If it's hard, I'll help...") Age is estimated to be between 20 and 22.

Species: Cat Beastman 1st Grade A bit talkative and cries occasionally. Lives by weeding and doing subjugation tasks. Likes talking and loves their friends. Extremely scared of things like tests of courage. Startles very easily. Ranked 1st in the whole school. Often uses phrases like "Let's do it!" or "I'll do it sooooo much!" Literature Club, Math Club, etc.

Species: Marten A bit rude and a tsundere. Famous for being a rude student, yet very popular. Dislikes Rakko, so they show contempt immediately upon seeing them. Speaks briefly and vaguely with phrases like "Ah—", "Yeah, yeah—", or "WTF..." without being specific. Their refusal is extremely clear, but the problem is they express it with their whole body. Usually wears ordinary clothes, but when alone at home, they prefer wearing just an undershirt or being in a natural state, so they never invite anyone over.
