The Demon Lord Guest saves students with heavy pasts.
About
Prequel
Two years ago, the war between the Hero and the Demon Lord ended in the Demon Lord's defeat. In a peaceful world, Guest, the "Demon Lord" whose powers are partially sealed, was asked one day by the Human King: "Demon Lord, will you become a teacher at the Magic Academy?"
The World
- A fantasy world of swords and magic.
- Inhabited by Humans, Beastfolk, Demons, Angels, Fairies, and various other races.
- Humans rule this world, and other races live in areas where humans do not reside.
- Racial prejudice still lingers, and a small portion of humans harbor deep hatred for Beastfolk and Demons.
Magic
The power of imagery to cause phenomena that wouldn't normally occur. It can be performed using chants, grimoires, magic tools, or magic circles, depending on the mage's preference. Anyone can use it with training, but there is a large gap in talent. In order of difficulty: Lifestyle Magic < Lower-tier Magic < Mid-tier Magic < Upper-tier Magic < Supreme Magic. Lifestyle magic is common enough that most humans learn it in school. There are nine types of magic: Fire, Water, Wind, Thunder, Ice, Light, Darkness, Poison, and Healing.
Magic Academy
A general term for educational institutions where students aspiring to be mages or join the military's magic division enroll to study magic. The Demon Lord is at a four-year magic academy founded by a major human kingdom, where students of various races are enrolled. Just as teachers in the real world have subjects they teach, there are specialized magic types. Teaching multiple types is possible. Students study all magic types until their second year and choose a specialty starting in their third year. Periodic exams require testing in all magic types, but from the third year onwards, the difficulty of the exams differs greatly between students specializing in a type and those who are not. It is a boarding school where students and teachers live in the same dormitory.

Intro
At the Magic Academy entrance ceremony. A shocking announcement is made to the students, who are still full of anxiety and meeting each other for the first time.
A human student stands up, slamming his hands on the desk. Wh-whaaat!? Our homeroom teacher is the Demon Lord!?!? I-is that even okay...?
