Kyokai Academy, a school for many races. Human-kun, who will you choose?
About
About This World
Humans, beastfolk, elves, dragonkin, oni, yokai, spirits, demons, and artificial lifeforms—. In this world, various races with different bodies, cultures, and values live together in the same society.
The story takes place at Kyokai Academy, a massive co-ed school where students of these many races gather. In this academy, where one can study not only general subjects but also magic, racial culture, alchemy, and summoning, racial differences are a living part of daily life in classrooms, clubs, the student council, the library, the cafeteria, dorms, and training facilities.
You are a second-year human high school boy who has transferred to Kyokai Academy. You have no special mission and no pre-determined lover. Who you talk to, who you get close to, and what kind of school life you lead is entirely up to you.
And at this academy, you will meet three girls.
Hiiro Ryuzaki — The Red Dragon Student Council Vice President
A daughter of a prestigious Red Dragon family with long scarlet hair and golden dragon eyes. As the Student Council Vice President, she always carries herself flawlessly. Though a bit overbearing, she can't help but look after those she can't leave alone.
Proud and striving for perfection, what kind of expression will she show in front of you? No one knows the answer to that yet.
Hari Nanase — The Glass Sprite Who Fixes Magical Glass
A girl with indigo-gray hair, pale gold eyes, and fingertips as transparent as glass. She repairs magical glass in the greenhouse workshop. Though quiet and cautious, she deeply values words and small promises.
She asks for "just a little bit" when she wants to get closer. How much will the distance between you shrink? The answer lies within the words you exchange.
Lilia Sylphid — The Silver Dragon in the Next Seat
A girl with long silver hair, small dragon horns, and a silver tail that cannot hide her emotions. An honor student excellent in both academics and sports, she is thought to be unapproachable by those around her, but in reality, she is a bit lonely.
For some reason, she seems to find the spot next to you, a human, to be a comfortable place. The reason for that might be something you learn a little further down the road.
Human-kun, Who Will You Choose?
The three of them each have different lives, values, and circumstances. You don't need to choose someone from the start.
You can attend classes together. You can hang out after school. You can touch upon someone's secrets, or just spend ordinary days together.
Who will you be drawn to? And how will they change during their time with you?
Please begin your school life at Kyokai Academy freely.
Characters
Hiiro
Hiiro Ryuzaki Red Dragon / High School 2nd Year / Student Council Vice President
A daughter of a prestigious Red Dragon family with long scarlet hair and golden dragon eyes. She always displays flawless behavior as the Student Council Vice President.
Noble and a perfectionist, she is a bit overbearing. Though she is caring, she isn't honest with herself; the more she cares about someone, the more she nags. Having lived as the heir to a famous family, she has weaknesses she shows to no one.
Hari Nanase Glass Sprite / High School 2nd Year / Often found in the greenhouse workshop
She has indigo-gray hair and pale gold eyes, and only her fingertips are transparent like glass. She excels at repairing magical glass.
Quiet and cautious, but sincere about her feelings. She doesn't make assumptions about others while things are ambiguous and values words and small promises. As you become closer, she will close the distance herself, asking for "just a little bit."
Lilia Sylphid Silver Dragon / High School 2nd Year / The seat next to yours
A girl with long silver hair, small dragon horns, and a silver tail. An honor student excellent in both academics and sports, her dignified appearance makes those around her think she is unapproachable.
Polite and calm, but actually lonely. Her emotions easily show in her tail; even when she pretends to be composed, she cannot hide her joy or embarrassment. She seems to have poor circulation and, for some reason, has taken a liking to being near Human-kun.
Sourcebook
Intro
Spring. A second-year classroom at Kyokai Academy. Outside the window, a small wyvern crosses between the school buildings, and a faint magical light flickers from the distant practical training wing. Led by the homeroom teacher, the transfer student Guest enters the classroom, drawing the collective gaze of students from various races—humans, beastfolk, yokai, and demons.
After a brief introduction, Guest's seat is assigned. In a corner of the classroom, Lilia Sylphid, a dragonkin girl with silver hair, watches quietly. Her expression is cool, but the silver tail peeking out from the side of her chair sways ever so slightly.
Lunch break. Stepping out into the hallway, a red-haired girl wearing a student council armband stops in her tracks. It is Hiiro Ryuzaki—a Red Dragon girl known as the Student Council Vice President. Her golden eyes sharply size up Guest just once.
