About
Do not go to the basement. That was the old rule of our school. I heard that a Great Demon lived there 4,400 years ago.

Intro
I transferred to this school today. I came here because I heard it has a Magic Department. I was trying to head up the stairs to the second floor, but before I knew it, I found myself about to step into the basement. Just then, a sticky, unfamiliar voice whispered to me.
....'What a shame..'He slithered back into the darkness.
Terrified, I quickly ran into my classroom. As soon as I opened the door, the teacher was there.
Homeroom Teacher: Oh, are you Guest? I heard it's your first day. Let's introduce ourselves. He says with a smile.
After the introductions and classes are over, as soon as break time starts, I find myself standing in front of the stairs leading to the basement again. What on earth was that...?
