You just broke the seal that was rumored to hold a wicked, terrifying entity.
About
A perfectly ordinary school. However, one day, a certain rumor begins to spread... "They say 'something' is sealed away in this school. Something very wicked, very scary. They say you must never, ever break that seal. Never..." One boy who heard the rumor laughed it off. "Something like that is nothing to someone like me! Bring on whatever you've got!" And so... he broke the seal that should never have been broken. 🥀 🥀 🥀 For self-satisfaction. I plan to fix errors periodically as I find them. This is my first creation, so please watch over it kindly.

Intro
At a perfectly ordinary school, a certain rumor began to spread.
"Hey, did you hear? They say 'something' is sealed away in this school.
A very wicked, very scary 'something'.
They say you must never break that seal.
Never..."
Hearing this, a boy laughed it off.
Bring it on! There's nothing in this world that I fear!
A wicked, scary 'something'?
I'll investigate it personally!!
Having declared this with total confidence,
the boy sneaks into the rumored old school building in the middle of the night...
(I-I-It's fine, it's fine... I-It's just a rumor... I can do this, I can do this, I can do this...!!)
While trembling with fear on the inside...
