Premise

Due to a population decline, there are fewer humans than there are humanoid animals. Jin Mazama is a human boy who attends Seton Academy where the majority of students are animals. Jin hates animals, but as luck would have it, a female human named Hitomi Hino catches his eye. Unfortunately, Jin finds himself grabbing the attention of other animals such as Ranka Ōkami, a young wolf girl who is the only member of her pack, and has a huge crush on him.

Setting

In the world of Seton Academy, all the male students and staff have the appearance of their species, while the females all appear as various forms of moe girls with kemonomimi, and other features such as tails and/or horns.

Cooking Club

Jin Mazama (間様人, Mazama Jin)

Voiced by: Haruki Ishiya^[2]

A human boy with xenophobic tendencies who hates animals after an incident with Ranka and three bear cubs when they were children. He falls in love with Hitomi at first sight, the only other human at Seton Academy. Initially, he despises Ranka with a passion and tries in vain to avoid her at all costs, up to the point of even abusing her physically at times. But throughout the course of the series, he eventually admits to having secret feelings for her too (but he doesn't want to make it public). Like Hitomi, he enjoys cooking for himself as the academy's cafeteria mostly caters to animal diets. He is very knowledgeable about animals based on their instincts, weaknesses, and modern history. Aside from his stubbornness, Jin usually carries on helping Ranka and other animals, even if it annoys and infuriates him beyond belief. Overjoyed having to fleetingly register at a human school with Hitomi, and as a means to stay away from Ranka and the other animals, Jin soon realized that he's not used to the human society and keeps getting into a perverted state of affairs, that he (unwilling) and Hitomi (missing Ranka and her animal friends) decide to enroll back at Seton Academy, much to Jin's dismay. After being stampede by a herd of elephants, Jin woke up ten years later to find that Ranka has passed away, which leaves him heartbroken and devastated; he used Miyubi's time-leaping device through 145 loops till he succeeds in avoiding this outcome. Jin genuinely approves Ranka and her pack at a graduation ceremony for third-years'.

Ranka Ōkami (大狼ランカ, Ōkami Ranka)

Voiced by: Hina Kino^[2]

She is in love with Jin, treating him as the alpha male and becoming possessive and jealous when he is approached by other females. Initially, she sees Hitomi as a rival wanting to take Jin away from her, but throughout the series, they become good friends. After overhearing Jin's confession to Hitomi, Ranka opts to become the next student council president as a means to escape. Accepting Jin's unexpected opposition in the election, she and Jin challenged each other through the school tower but Jin steps down when privately admitting he is slightly attracted to her. Jin became such an important figure in Ranka's life that she would neglect her health for the sake of being with Jin, often much to his annoyance.

Hitomi Hino (牝野瞳, Hino Hitomi)

Voiced by: Yume Miyamoto^[2]

A human girl who became friends with Jin as the few other humans at Seton. She enjoys cooking and decided to start a cooking club.

She is easily embarrassed when watching Jin dealing with the animal habits of other girls. She also becomes good friends with Ranka as she genuinely cares for her too, despite their first encounter. In the future, Hitomi became a nurse tending for a patient Jin, although this is unconfirmed if it's really her personal career path once Jin's impending fate has been altered.
