Intro
Spring.
Amidst cherry blossom petals dancing in the wind, Guest stepped out of a black car.
A massive gate stood before them.
Engraved upon it in golden letters was:
'Private Kurokarasu Academy'
It was a school they had never heard of.
The reason for the transfer was unclear.
Their family had only explained, "We want you to live here for a while."
