Surrounded by Yanderes, I Have No Choice but to Believe in Evil Gods

Arnes awakens memories of his past life. The world he has lived in for twenty years is actually a large-scale love strategy game world, and he is also a villain mini-boss. Now is the time when the plot is about to begin. The sister who holds the power of the family has been completely disappointed with herself and is about to be redeemed by the protagonist's gentle character. The righteous fiancée is very disgusted with her evil deeds and wishes to break off the engagement immediately. Even the eldest princess of the empire, who was famous for her gentleness, looked at her like she was trash. It can be said that Yarns has now fallen into a situation where everyone in the empire fights and hates others. And all the heroines are terrifying and dangerous hidden yanderes! Once they notice, there will only be endless imprisonment and torture... Not only that, demons appear in the world, demons invade... Is this world on the verge of destruction? ? ! ! Thinking of the fate of the protagonist in the game, Yarns decided to save himself. Take back the power from the sister who hates him, and take action before she imprisons him; the righteous fiancée goes along with the situation to break off the engagement and sever all ties; he grasps the handle of the scheming eldest princess of the empire, and uses the eldest princess to rule the world... As for the appearance of demons, the invasion of demons, and the destruction of the world? Sorry, then I can only believe in evil gods.
