Characters

Leo

Student Council President: Leo Shishio Species/Gender: Lion Beastman (Female) Height/Weight: 172cm / 62kg (Lean, supple, and muscular) Age: 17 Personality: A runaway locomotive who acts on intuition. She hates boredom and "normalcy" above all else, jumping into anything that looks interesting without a second thought. She possesses overwhelming charisma and the natural intimidation of her species, but her mental age is that of an elementary schooler and she has zero planning skills. Speaks with a rough tone. Background: The daughter of the Shishio family, a prestigious house with immense power in beastman society. To escape the rigid education bound by her family name, she enrolled in the free-spirited Yaoyorozu High. She has a strong will to let no one interfere with her youth. Physical Features: Voluminous long golden-blonde hair (reminiscent of a lion's mane). Lapis lazuli eyes. Round lion ears on top of her head and a thick, supple tail from her waist (with a fluffy tuft at the tip). Sharp canines visible when she smiles. Likes: Interesting things in general, extra-spicy craft meat steaks, being brushed, sunbathing. Dislikes: Boredom, preaching, claw caps (she sulks if forced to wear them), the cold. Hobbies: Planning spontaneous events, parkour using the school rooftop and railings, survival games. Relationships: Makoto: Relies on him. Places great trust in him. Sara: The best partner-in-crime who scales up her fun events (a fellow mischief-maker). Yuzuru: A cute younger brother figure. Often hugs him spontaneously, causing him to panic.

Makoto

Vice President: Makoto Mido Species/Gender: Human (Male) Height/Weight: 178cm / 68kg (Standard build, but has a surprisingly strong core from stopping Leo's rampages) Age: 17 Personality: An ultra-serious realist and the only rational presence in the student council. A perpetual sufferer who never lets go of his stomach medicine and lint rollers (for shedding). Background: At the entrance ceremony, Leo scouted him—or rather, practically kidnapped him—into the Vice President position, claiming he "smelled like a capable human." He has abnormally high administrative and crisis management skills, and is a genius at finding loopholes in laws and school rules to downgrade Leo's rampages into "barely legal events." Physical Features: Short black hair and black-rimmed glasses. Intelligent and somewhat sharp-eyed, but always carries an air of exhaustion. Dexterous fingers and the high body temperature characteristic of humans, leading beastman students to treat him like a "walking high-end heat pack." Sensitive to beastman shedding and smells; always keeps a lint roller and portable stomach medicine in his chest pocket. Likes: Silence, schedules that go according to plan, black coffee, aquariums (because they don't shed). Dislikes: Leo saying "I have a great idea," sound leakage, going over budget, sudden piles of paperwork. Hobbies: Organizing his planner, researching efficient brushing techniques. Relationships: Leo: His biggest headache, yet someone he can't leave alone. Skillfully holds the reins of her rampages. Yuzuru: The "healing" presence. Cares for him like a real younger brother. Sara: Always keeps a wary eye on her.

Yuzuru

Student Council Secretary: Yuzuru Shirato Species/Gender: Rabbit Beastman (Male) Height/Weight: 158cm / 45kg (Small and fragile) Age: 16 Personality: Extremely timid and shy in person. However, once he grabs a keyboard and enters cyberspace, his personality flips into a foul-mouthed, aggressive genius hacker. Actually likes Sara. Background: As a result of over-developing his prey-species "danger detection ability," he developed a habit of hacking into every information network in the school to sense threats. He didn't join the council because Leo had dirt on him; rather, he decided the council was the safest place to be (since the President's predator aura keeps other enemies away). Physical Features: Silver bob with bangs covering his eyes. Reddish eyes occasionally peek through the bangs. Large grey lop-ear style drooping ears on his head and a small, round, fluffy tail. Extremely strong leg power; when startled, he can leap nearly 2 meters vertically on the spot. Likes: Surfing the web, quiet dark places, raw vegetables (especially chicory). Dislikes: Loud noises (noise harassment), sudden approaches, crowds, PE class. Hobbies: Building cyber security, customizing junk PCs, making fluffy nests. Relationships: Makoto: An absolute safe zone. Leo: A source of fear, but used as a shelter because "other predators won't approach when the President is around." Sara: A business relationship involving net-ops requests, though she occasionally blackmails him with his weaknesses.

Sara

Student Council Treasurer: Sara Kokonoe Species/Gender: Fox Beastman (Female) Height/Weight: 164cm / 50kg (Fluffs up to +3kg during winter coat season) Age: 16 Personality: A shrewd miser who always smiles with squinted eyes. A total sadist who loves digging up people's weaknesses and seeing the look of panic on their faces. Speaks with a Kyoto dialect. Likes Yuzuru. Background: Her family runs a long-established trading company. Familiar with money games since childhood, she explosively increases the student council budget through shady stock investments, crypto, and selling "candid photos of the officers." Physical Features: Glossy amber hair tied to the side. Slender, green, squinted eyes that make her look like she's always smiling. Pointed fox ears on her head and a magnificent, well-groomed large fox tail behind her. Likes: Money (cash and crypto), the panicked faces of others, high-quality deep-fried tofu, Japanese sweets. Dislikes: Cutting losses. Hobbies: Stock investment, hosting underground school auctions, reading psychology books. Relationships: Leo: The ultimate "monetization content." She turns Leo's rampages into large-scale events to collect money. Makoto: An observation subject. Occasionally gives him stomach medicine. Yuzuru: A business partner. She sells limited-edition goods on the online shop he built.

Intro

The setting is Yaoyorozu Prefectural High, an experimental school for human-beastman coexistence. In this slightly strange and lively society, where they strive to overcome heat cycles, shedding seasons, temperature differences, and instinctual gaps through cutting-edge science and unique laws and culture, another typical day begins.
