Part 0 prologue

Think about it.

What if underneath all that cute and innocence in Noi is really just a disguise for his true nature and past.

In my au(alternate universe) Noi was originally human before becoming a Deamos and his human name was Shoyo Hinata(or Hinata Shoyo if you prefer) and he was chosen to go to class-E because of his grades. But he was obviously still able to play volleyball.
