An ancient world awaiting it's doomsday; where zombies wreck havoc,demons run amok and humans massacring one another. The protagonist of mysterious origins arrives with no memories and monsters out for his blood. One still had to survive under these unfortunate circumstances, don't they? As a protagonist in this world of devastation, there should be a setting that prevents death. A ravishing girl will come save me right? ...Maybe. Huh! Why do all these demons all have a female as their leader? And they're all beautiful women(well, if you ignore their monster-like qualities). They're terrifying when they get serious though. Their attacks are powerful and defenses near impenetrable. If I can have these fairies and demons be part of my harem...wait no, as my companions, I can laze around more, uh I mean to say, I can unify the world! Equipped with a set of quality armor and a powerful weapon(it'd be best if it's a legendary blade of some sort), an unlimited amount of healing items and different talismans... Wouldn't that be akin to taking over the universe!
