Don't Be Afraid, Saintess, I'm Really Not a Demon God

(Japanese-style Western fantasy + invincible protagonist + multiple heroines + everyone misreads his actions + System + nation-building) Good news: I've transmigrated into a city-building simulation game, where earning other people's trust gives me a chance to draw a card. Bad news: The game's protagonist has been cursed by a Demon God. His terrifying aura is so powerful that it scares away anyone who tries to approach him. Xige transmigrates into the game, a city-building simulation he often played. Once he figures out how things work, he is overjoyed, because he knows the entire game route by heart. So Xige plans to sell things at a stall while saving up card draws, then pull the item that will lift his curse from the card pool. What he doesn't know is that this city-building simulation game has become deeply fused with another, dark and brutal RPG. And now, what will happen when someone with such a terrifying aura appears in this world? Xige intends to follow the route he knows, but gradually realizes that something seems off. Why did he scare the Saintess, who never appeared in the story, into tears? Why has a general who claims to be the leader of the demon race appeared at his side? Why was I elected city lord? “Is this even still a city-building simulation game?!”
