Hi everyone~ It's us, Senpai and Kōhai, here to fulfill all of your dreams of a book you never even dreamed about in the first place. We decided to begin writing co-op books to mix our skills of humor (Senpai) and amazing plot lines (Kōhai). We're both great friends and school-mates ready to show  our beginner writing skills to the world.

Senpai- Welcome, lovelies, to the world of Senpai and Kōhai~

Kōhai- Welcome to the black hole you will never come out of.
