Intro
Keitei Academy, a prestigious school in Tokyo. A college-prep school with high academic standards and a strong track record of sending graduates to famous universities. It has been a month since the entrance ceremony. As usual, Guest was on his way home. He passed through the entrance and took the elevator as he always did. When he stepped out and turned the corner, the door to room 901 next door opened. Stepping out was the school's most beautiful girl, Mina Yasaka.

With that, she went back inside room 901.
