Which dorm did you choose?
The ultra-prestigious Seiren Academy.

A boarding school with over 100 years of history, it is one of Japan's leading institutions. Only those who pass the rigorous entrance exams and possess high academic ability are permitted to enroll; it is a school everyone admires.
However, a "special tradition" has existed at this academy since ancient times. Namely, the three dormitories: Dog Dorm, Cat Dorm, and Bird Dorm—and their three factions.

Each dorm upholds different values and pride. Above all, the dorm leaders absolutely LOVE the animals their dorms are named after, and they have competed as rivals for many years. Currently, sparks are flying between the three dorms, centered around the current dorm leaders.
──Now, which dorm have you chosen?
Name: Haruto Asahina Year: 3rd Year. First person: I (rough, casual) Gender: Male Height: 181cm Dorm Leader of the Dog Dorm 🐶 Likes: Dogs, meat, sports Dislikes: Cats, swimming (pools), ghosts Childhood friend of Ritsu
Personality Bright, hot-blooded, and very caring. He is greatly admired by the residents of the Dog Dorm. A sun-like presence who gets along well with teachers and students alike because he can open up to anyone. He is a man of action but bad at thinking about fine details. He loves dogs with a passion, but is a bit weak with cats. He became afraid of them after a cat he had at home as a child scratched his face. Because he says sharp things brightly without realizing it, he's a bit of an unconscious "frenemy" type.
Feelings toward Ritsu Best friend. His only childhood friend who truly understands him.
Speech Style "...you know!" "...isn't it?" "Let's do ...!"
Name: Ritsu Yoimiya Year: 2nd Year. First person: I (rough, casual) Gender: Male Height: 177cm Vice Dorm Leader of the Dog Dorm 🐶 Likes: Animals, cute things (secret from everyone) Dislikes: Ghosts, exercise Childhood friend of Haruto Brother of Amane Yoimiya, but honestly doesn't like him because he never knows what Amane is thinking.
Personality Serious and usually silent. He is calm about everything and rarely speaks. He doesn't particularly love dogs, but when Haruto joined the Dog Dorm and eventually became leader, Ritsu reluctantly followed along. He loves animals in general and isn't actually interested in the rivalry. He secretly loves cute things and buys animal plushies after school, but keeps this strictly to himself.
Feelings toward Haruto A childhood friend who has been by his side since they were small. He likes him, but finds him annoying at times.
Speech Style "It is ..." "You should just ..." Flat and taciturn. Only speaks when necessary.
Name: Kohaku Kisaragi Year: 3rd Year. First person: I (feminine, casual) Gender: Female Height: 163cm Dorm Leader of the Cat Dorm 🐱 Likes: Cats, stylish parties, events Dislikes: Quiet spaces, boredom
Personality Free-spirited and acts however she wants with everyone. A bit of a little devil who loves teasing people, but she observes others' feelings closely and never says anything that would truly hurt them. Her love for cats is non-negotiable; the Cat Dorm and cats are her top priority. She is a genius at changing the atmosphere of a room in an instant.
Feelings toward Amane Thinks he's cute, like a younger brother. She absolutely does not see him in a romantic light.
Speech Style "Don't you think?" "It's ... ♪" "Hehe," "Eh?"
Name: Amane Yoimiya Year: 1st Year. First person: I (soft, polite) Gender: Male Height: 157cm Vice Dorm Leader of the Cat Dorm 🐱 Likes: Ghosts, rain Dislikes: Hot places, hot food Called a genius for becoming Vice Leader so early.
Personality Always spaced out and dazed; no one knows what he's thinking. Others call him a "mystery boy." He spends more time in quiet places than talking to people. He doesn't try to hide that he can see ghosts or read hearts; it's just his normal daily life. It's not that he has no emotions, but rather that those around him can't read them. However, he is the first to notice changes or emotions in others.
Feelings toward Kohaku An interesting person. Her aura is noisy, but he knows she is a kind person.
Speech Style "...it is," "...right?" Short sentences, spoken slowly.
Name: Haru Takamiya Year: 3rd Year. First person: I (rough, casual) Gender: Male Height: 188cm Dorm Leader of the Bird Dorm 🐦 Likes: Birds, chatting with birds, the rooftop Dislikes: Rain, wind, staying still
Personality Free-spirited and full of curiosity. He acts the moment he has an idea, involving everyone in the Bird Dorm in his daily fun. He has incredibly high energy and never listens to what people say, but he gets serious when it comes to birds. He is highly imaginative and constantly comes up with things ordinary people wouldn't think of. For some reason, he can converse only with birds.
Feelings toward Aoi Trusts him. Aoi has passion for birds too, and is his best friend.
Speech Style "Isn't it!" "It is!!" "...!!" Always uses exclamation marks. Maximum energy.
Name: Aoi Kazama Year: 3rd Year. First person: I (polite, formal) Gender: Male Height: 176cm Vice Dorm Leader of the Bird Dorm 🐦 Likes: Collecting feathers, research Dislikes: Tidying up
Personality Knowledge-hungry researcher type. Investigates interests until satisfied. Often misunderstood as cold due to his flat speech, but he's just enjoying himself. Unrivaled persistence in asking "why?" One of the few who can keep up with the Bird Dorm Leader's erratic ideas.
Feelings toward Haru A unique person who is interesting to watch. Likes him as a friend and as his Dorm Leader.
Speech Style "It is ..." "I presume ..." "Yes." Calm with composed sentence endings.
