This tale starts with a dream... Your dream.
Help me... Please help me. I was locked up by a demon. You are my only hope, help me get out of here.
＂I beg you. You must find me.＂
You hear the distant voice of an unfamiliar man and wake up to find yourself in a place that looks like a courtroom. The stern voice of the man in the seat of the chief judge echoes.
＂We welcome you, human, to the demon student council.＂
You are selected to become an exchange student at RAD, a school for demons.
Awaiting you are 7 demon brothers each with their own peculiarities... and a mountain of tasks?!
There is only 1 rule you have to remember...
