Toyo Akutsu unfortunately died in an accident, but the next moment he was somehow reincarnated in the world of a famous RPG as Ashnold, the weakest of the Four Heavenly Kings. At this rate, he will lose to the Hero and die. Even if they were miraculously defeated, the Heroes would raise their level and return. To survive, he has no choice but to use the forbidden bug technique 「Betrayal Bug」 to make the Hero’s group become his followers and control their bodies and minds. Will Akutsu (Ash) be able to subjugate all the heroines, build a harem, and survive the death flag event?
