My name is Keima Masuda, and my hobby is spending each day doing exactly nothing... but one fateful night, I was summoned to another world where I met a blonde young girl who I named Rokuko.

It's a checkmate already. I've gotta break out of this impossible situation so I can stop working and just sleep!
