The mc is approached by a strange girl that claims he is supposed to be the "hero". Another girl approaches him saying he needs to be careful. Turns out the mc needs to die to get reincarnated so the heroine does her best to kill him in the modern world.
All a psychopath! A princess try to kill the hero and a demon princess try everything to ensure the hero didn't die and reincarnated to their world. Lots of boob and fanservice
