Prologue

μ's were having a small graduation party for the third years on a dark and stormy night. They learnt a legend that the school used to be a sacred place where people used to spawn in undefined mortals...

A few seconds after learning that legend, they were trapped in the school, 100 years into the past...

The members would have to face trials, endless torture and even the loss of their members just to leave the never ending nightmare...

Warning!
If you can't take gore and stuff... especially death of some of the members, please do not read.
