Plot
This is the story before the world came to an end. Ichinose Guren, a 16-year-old, enters the magical teacher training school, First Shibuya High School. What I was waiting for was suppression from the Hiragi who leads the overwhelming sorcerer organization "Order of the Imperial Demons", and a reunion with a girl who gathered her thoughts on a young age --- against the fate "School magical fantasy", start!
