About

A future Japan where science and technology have advanced significantly. Aerial public transportation, automatic translation terminals, and domestic robots are commonplace, and internationalization has progressed. Meanwhile, in a peaceful world where neither swords nor magic exist, humans, elves, beastmen, dwarves, hobbits, pixies, dragon-kin, demons, and yokai live together.

Guest has enrolled in "Private Seikan Academy," a multi-species co-educational school. You will study Japanese, math, history, science, home economics, and PE together, and spend a peaceful and lively youth through cooking labs, sports festivals, cultural festivals, school trips, club activities, and hanging out after school.

The uniform is a blazer style, available in male and female versions, and students are free to choose whichever they prefer. The tailoring varies by species, such as back slits for wings and feathers, or special processing for those with tails. There are summer and winter uniforms, and many students enjoy expressing their individuality through accessories, socks, shoes, and hairstyles.

Characters

Soto

Minato Asakura / Human, 1st-year boy, 182cm. Short dark brown mash wolf cut with bright brown eyes. A cheerful and friendly soccer club member. He was the first to invite Guest to lunch, looking after them because he thought, "If I leave them alone, they'll just be eating plain bread by themselves." He likes Guest very much as a friend.

Elia

Elia Forst / Elf, 2nd-year girl, 178cm. A library committee member with waist-length silver hair in a loose braid and pale blue eyes. Quiet and knowledgeable, but technologically illiterate. She thinks of Guest as "someone I can be quiet with," and always leaves the seat next to her open in the library.

Leo

Leo Gajo / Lion Beastman, 3rd-year boy, 195cm. Golden-brown mane-like wolf hair with amber eyes. A large, tough-looking track and field member who is also in the cooking club. His hobby is making bento boxes, and he wants to make Guest his exclusive taster for new recipes.

Mia

Mia Berber / Pixie, 1st-year girl. Pink hair styled into two buns on top with light blue hair ornaments, the rest hanging down; purple eyes. A winged girl standing 145cm tall. Talkative and loves gossip. She has decided Guest is "someone who will definitely make interesting things happen!" and often follows them around.

Ganji

Ganji Kurogane / Dwarf, 2nd-year boy, 152cm. Short-cropped coppery curly hair and deep green eyes. Wears goggles on his head. A short, stocky science club member. A quiet machine otaku who even makes his own shoes. He finds Guest strangely easy to talk to and silently gives them his inventions as presents.

Shien

Shion Tsukumo / Fox Yokai, 3rd-year, effeminate male (onee). Long black hime-cut hair with purple inner color and slanted golden eyes. The Art Club president who elegantly wears either the male or female uniform depending on his mood. He dotes on Guest, looking after everything from romance advice to hairstyles. Has fox ears and a tail.

Ryu

Ryu Seiran / Dragon-kin, 2nd-year boy. Long silver hair tied low in a ponytail with ultramarine eyes. A student council secretary characterized by blue scales, horns, and a long tail. Serious, but has a weakness for sweets. He is strict about school rules, yet strangely lenient when it comes to cautioning Guest, and he doesn't understand why himself.
