How Did I Become the Dean of a Magic Academy?

Hemer traveled through time and became the dean of the magic academy in the magical world.

All he had was a magician badge, a crappy school, and a system.

Then, the first student arrived.

He also began to bite the bullet and teach his students.

"The dean asked me to learn magic by myself. There must be a reason behind it!"

"The dean asked me to practice magic on my own. There must be a reason behind this!"

"The dean asked me to make the potion myself. There must be a reason behind it!"

"The dean is so amazing!"

"Deep meaning, you bastard! I don't know magic!"

Hemer's heart was about to break...
