Upon his death, nineteen year-old Aikata finds himself in an afterlife to which he does not belong, one reserved for a legendary order of Heroes fighting an endless war against Demonic invaders.
Unable to leave, and unwelcome by the Heroes who dwell there, the self-proclaimed 'otaku-loser' learns his very presence may summon even more Demonic hordes to that already beleaguered realm.
As talks of Aikata's imprisonment – or execution – ensue, a simple request from the world's creator sets him upon a clandestine, moon-lit walk that will decide the war once and for all.
Armed with a strange power he does not understand, and accompanied by shy and reticent companion addicted to cheesecake, Aikata must escape Hero and Demon alike, as he tries to find his true place and purpose in that strange 'reality'.
