"You have to save this world. That's not my whim, the world itself desires it."
The transfer student by the name Mimiyo said that and gave Kazuki a syringe. By using it he traveled to a different world "Mundos" that, in some ways, resembles reality. There he fought, as a savior, against monsters called "Mortalis" that destroy the very fabric of the reality he knows. That brought an end to his "role" and "everyday life" he was so fed up with. Like mad he spent his time as a hero fighting for the world's salvation. A true story that from a first glance resembles drug-induced hallucinations.
