Masaru Katou - a brave and kind-hearted student - was on his way home to celebrate his younger sibling's birthday but met an unexpected demise. Upon awakening in a compact chamber with a stunning view of Tokyo's skyline, Masaru discovers that he's not alone.

Masaru is abruptly given a firearm before being teleported into the heart of Osaka, where his mission is simple: obliterate any extraterrestrial entity he encounters.
