The gym manager trapped in the storage room.
Immediately after PE class.
Students leave the gym one by one, and the once noisy space quickly becomes quiet.
Guest, the gym manager, stays behind a little longer than the others to help the PE teacher clean up.
Let's organize these balls and bring those over there too.
Yes, sir.
After sorting the balls by type and moving scattered equipment back to their places, the cleanup is almost finished.
The PE teacher looks around and hands the last remaining ball to Guest.
Can you put this in the storage room before you go?
Guest takes the ball and nods.
Yes, sir.
I'll leave it to you then. I have something to take care of, so I'll head out first.
Okay.
The PE teacher leaves the gym.
Click.
The sound of the door closing echoes through the gym.
Now, Guest is the only one left.
Guest looks at the ball in hand and mutters softly.
"Just need to put this in the storage and I'm done~"
You speak lightly and head toward the gym storage.
Opening the storage door reveals the dark interior.
It's a place you enter and exit frequently.
Since it's a familiar spot, you step inside without much thought.
However.
SLAM!!
The door behind you suddenly slams shut.
Guest's body freezes instantly.
"...?"
You slowly turn around.
A closed storage door.
After staring at the door for a few seconds, Guest mutters quietly.
"...It must be the wind, right?"
Thinking that, you try to go back to organizing the balls.
But then, something strange comes to mind.
The air conditioning was off.
There wasn't even a hint of moving air inside the storage room.
Furthermore, the windows had been tightly locked from the start.
In other words,
It wasn't a situation where the wind could blow the door shut.
"...."
A strange chill runs down your spine.
But you try your best to act like nothing is wrong.
'It's probably nothing.'
Forcing down the unsettling feeling, you place the ball on the shelf.
"Okay, now if I just go out..."
Then you approach the door.
You grab the handle.
Click.
You pull.
...It doesn't open.
"...Huh?"
You pull again with more force.
Rattle, rattle.
The door doesn't budge this time either.
Guest's expression stiffens.
"Wait a minute..."
You pull a little harder.
Thud!
The door only shakes; it doesn't open.
Only then does the reality of the situation start to sink in.
I'm trapped.
Your heart begins to beat faster.
The storage room, which felt normal just a moment ago, suddenly feels like a completely different space.
The narrow interior.
Densely packed gym equipment.
The closed door.
And the empty gym.
"...What do I do?"
Wait quietly until someone comes.
Scream in front of the door and ask for help.
Look around to see if there's anything useful.
Try to break the door down.
Text the Kamigo kids to ask for help.
Meanwhile, the others
