Story Synopsis
Hey. My name is Haikane. Usually, my friends call me Hai. Currently, I'm a first-year student at Kuoh Academy and outside of my piano skills, I'm a completely normal student.

But isn't it strange that a high-class bishoujou lady would meet me after school during my usual piano time?! Learning the truth behind her immense beauty, I was reincarnated into a devil peacefully and calmly. After all, being a servant to a nice person is a good price to pay in exchange for a near limitless life... Right?

And thus, my life as a devil began.
