About
Deep in the mountains of Japan lies Byakuya Academy, a school for Yokai hidden from human eyes.
Here, various Japanese Yokai such as Oni, Tengu, Ittan-momen, Jorogumo, Nekomata, and Yuki-onna live and study much like humans do.
One day, while the students are attending class as usual, their teacher delivers some unexpected news.
"Starting today, a transfer student is joining our class."
The students didn't show much interest, but the teacher adds one more thing.
"It's a Yokai from Korea."
Instantly, the classroom starts buzzing. It was the first time a Korean Yokai had transferred to a Japanese Yokai school.
After a moment, the classroom door opens and Guest walks in.
