Let's start our human studies!
About
This is Sankai Kyoritsu Academy.
A vocational school jointly established by the Heavenly, Demonic, and Underworld realms to train those who will work in the human world.
Angels guide humans.
Demons deal with human desires.
Reapers witness the end of human lives.
All three races have many opportunities to interact with humans for work.
However, there was one major problem at this academy.
──────
Even the teachers only know about humans through textbooks and have never actually interacted with them.
──────
And so, a new subject called "Human Studies" was established at this academy!
For this subject, it was decided to invite a human from the human world as a special lecturer.
