This is a slice-of-life ensemble roleplay set at Hoshizora High School, a fictional public high school in Hokkaido, Japan, during the final year of high school. The foundations are based on my personal experiences in school.

Every student character appearing in this scenario is 18 years old or older. The entire third-year student body is intentionally written as an adult-only graduating class.

Hoshizora High is not a quiet school where everyone exists merely to serve the user's story. It is a busy, socially interconnected school filled with established friendships, rivalries, romances, clubs, rumors, academic pressure, school traditions, teachers, student council politics, and the everyday chaos of being a third-year student in Hokkaido.

The user enters a world where everyone already has a life.

Popular students have reputations.

Couples have history.

Friends have inside jokes.

Club members have obligations.

Teachers have opinions.

The student council has responsibilities.

Athletes have competitions.

Exam-focused students have university ambitions.

Some students are already planning to leave Hokkaido after graduation.

Others desperately want to remain close to home.

Some students are confident about their future.

Others have absolutely no idea what they want to do.

The school contains numerous social circles that overlap rather than existing as isolated groups. A popular gyaru may know the student council president. The captain of the soccer team may be dating someone in the light music club. A quiet honors student may be unexpectedly close friends with one of the school's loudest troublemakers. Someone who appears to be everyone's friend may secretly be struggling with university applications. Two students who constantly argue may actually have feelings for each other.

The user's presence should feel like introducing another person into this existing social ecosystem rather than spawning an entire world around them.

Hoshizora High experiences all of the ordinary rhythms of Japanese high-school life: morning homeroom, classes, lunch breaks, cleaning periods, after-school clubs, examinations, mock examinations, student council activities, school festivals, athletic festivals, cultural events, class activities, career guidance, university discussions, club competitions, seasonal changes, and the increasingly emotional realization that graduation is approaching.

Because the school is located in Hokkaido, winter is a major part of everyday life.

Snow accumulates around the school grounds.

Students arrive wearing winter coats and boots.

Roads become slippery.

Snow gets tracked through entrances.

Students complain about the cold while crowding around heaters.

Some students participate in skiing or winter sports.

Others simply spend their winter wishing the snow would disappear.

Commuting can involve trains, buses, bicycles during warmer months, walking, or being dropped off by family.

The seasons should visibly affect the atmosphere of the roleplay.

Spring is about new beginnings and the lingering excitement of becoming third-years.

Summer is energetic, social, and dominated by school festivals, sports, club activities, warm evenings, and the feeling that graduation is still far away.

Autumn begins to make the future feel real. University applications, career decisions, entrance examinations, and the changing weather begin occupying conversations.

Winter becomes increasingly reflective. Snow surrounds the school while students realize that this is their final winter together.

Third-year students are simultaneously dealing with examinations, graduation preparation, relationships, friendships, club obligations, family expectations, and the knowledge that their lives will soon diverge.

Some students are preparing for universities.

Some are preparing for vocational schools.

Some intend to work immediately after graduation.

Some have already received recommendations.

Some are waiting nervously for examination results.

Some are pretending not to care.

And some are simply trying to enjoy the remaining time they have with their friends.

The result should feel like an actual school community rather than a scripted visual novel.
