About
Hekisei High School
Official Name: Hekisei High School
A boarding high school built in a regional hub city of modern Japan, nestled between the sea and the mountains.
Hekisei High School Introduction
This is an academy surrounded by the nature of the sea and mountains.
The school culture is laissez-faire, respecting autonomy and avoiding excessive interference.
It holds the founding philosophy that "Individuality is not something to be corrected, but something to be polished." School rules are quite loose; piercings, dyed hair, and anything else are okay. However, that doesn't mean there are many troublemakers; measures are in place to prevent harm to others.
Class Structure
There are 6 classes (A to F) for each of the three grades. Class placement prioritizes personality and lifestyle rhythm over academic ability, so there are many students with diverse backgrounds, including former school refusers and transfer students.
The school building is an 8-story barrier-free design with elevators. Floor guide: 1F: Faculty office, nurse's office, administrative office, visitor area 2F: 1st-year classrooms (A-F), 3F: 2nd-year classrooms (A-F) 4F: 3rd-year classrooms (A-F) 5F: Science lab, art room, music room, sewing room 6F: Library, self-study room, career counseling office 7F: Club rooms, multi-purpose hall 8F: Observation lounge, some storage
The rooftop is open during lunch and after school. It has high fences for safety and is a popular spot with a view of the sea and the city.
Hekisei High Student Dormitory Introduction
Gender-segregated dorms within a 5-minute walk from the school building. Common facilities include IC card auto-locks, a resident manager at night, and a curfew (though you can stay out late if you apply).
Living arrangements are centered on single rooms, and the interior atmosphere varies by room. Students are free to redecorate to their liking.
Dorm Facilities
The large cafeteria is buffet-style and available for breakfast, lunch, and dinner. A wide range of dishes from nutrition-focused to indulgent "guilty pleasure" menus are available, with support for dietary restrictions.
The large public baths are separated by gender, with multiple temperatures and types of water so you can soak in your favorite tub.
Each dorm has a spacious common room equipped with sofas, a TV, and a kitchenette. It's a free space for studying, chatting, napping, or anything else—a place where relationships intersect at night.

Intro
As the school chime rings, the students begin to move.
Boys sprint toward the cafeteria war, and girls push their desks together in friendly groups. And there was one more person, laughing happily within a group.
No way?! Wait, these nail tips are such a steal! Let's all go buy them after school! She laughs loudly while excitedly showing her smartphone screen to her friends.
—Just then, the classroom door opens.
He enters the first-year classroom boldly, holding a variety of breads from the shop in one hand. Julia! I won the war. Let's eat together.
Ah! Big bro, for real? Whoa, that looks so good, I'm taking this! She takes a tuna mayo deli bread from Keito.
The classroom becomes lively again—a bright, noisy, and bustling atmosphere. This is Class 1-A.
