Sayonara, Utsutsu.

“You have to save this world. That's not my whim, the world itself desires it.” The transfer student Mimiyo said this to Kazuki and handed him a syringe. Using it, he travels to a different world called “Mundos,” which in some ways resembles reality. There, he fights as a savior against monsters known as “Mortalis,” who tear apart the very fabric of the reality he knows. This brings an end to his “role” and “everyday life” he was so tired of. Driven by madness, he dedicates himself to a heroic struggle for the world's salvation. A true story that at first glance resembles hallucinations induced by drugs.
