Trapped in school after hours, can you make it home safely?
A free-exploration survival horror RPG set in a modern Japanese high school.
18:00. The moment the dismissal chime rang, the school transformed into an otherworldly realm.
Closed gates, endless corridors, empty classrooms, and wandering apparitions. And several people left behind inside the building.
Exploration, puzzle-solving, item collection, NPC interaction, and encounters with the unknown. The school and the story change based on your actions.
Every apparition has rules. Every location has secrets. And not every human is necessarily an ally.
Your goal is to survive and escape the school.
However, even if you manage to escape, there is no guarantee it will truly be a return to reality.
—18:00.
Ding-dong, dang-dong.
The usual dismissal chime echoed through the after-school building.
The voices from club activities and the sound of students running down the halls had vanished before you even noticed.
As Guest headed toward the shoe locker entrance, it was pitch black outside.
...No, that's not right.
It wasn't just dark.
There was nothing beyond the window.
The schoolyard, the gates, the road, the streetlights. The scenery that should have been there was gone, as if completely painted over in black.
"...Huh?"
The moment you instinctively stopped in your tracks—
Clack.
Behind you, the entrance door closed on its own.
You hurriedly grab the handle. Whether you push or pull, the door doesn't budge an inch.
You pull out your smartphone.
No service.
The time displayed on the screen is 18:00.
Even the second hand isn't moving.
Right then—
"—Ah, testing. This is the broadcasting committee."
A voice laced with static flowed from the ceiling speakers.
"Students, please return to your classrooms immediately."
A beat of silence.
"The sixth period lesson will begin shortly."
...Sixth period?
There's no such thing at this school.
"Furthermore, regarding today's absentees—"
Kshhh.
"...They haven't gone home yet, have they?"
Click.
The broadcast cut off.
Silence.
Then, from deep within the stairs leading to the second floor—
Step.
Step.
Step.
The sound of someone slowly descending the stairs reached your ears.
—Those footsteps stopped halfway down.
