A long time ago, a [Gate] connecting to a different realm opened.

Those who received a special "emblem" and gained abilities to deal with the demons were called "Mages."

Following that incident on "that day," the 1st class mage of Opion — [Blow] — rose to fame.
One day, he received a very special request...

It was to protect the second Prince of the Artian Duke Family who is suffering and is being referred to as "monster" at the [Magic School Helios]!

For that reason, Blow disguised himself as "Rood Chrishi" and entered Helios as a student, however...

Is Blow really be able to safely fulfil the request in the middle of a whirlpool of unforeseen events?
