Synopsis

A growth fantasy where the protagonist, possessed by a character-raising game, turns the weakest Demon King into the strongest! I had been raising a character in the character-raising simulation game "Evil Queen Maker" with the utmost care, only for the final villain to suddenly make her his bride. When I sent a lengthy complaint about the ending… “Then go ahead and create a better ending yourself,” and I ended up possessed by the game’s “Evil Queen Maker”! To escape this game, I have to raise the Demon King and see the ending. But the Demon King I have to raise, Seere,” is only 7 years old. The weakest character in the entire world. Caught up in war and intrigue, as Seere grows older, he starts worrying only about how to gain the attention and affection of his teacher, Nahen. “How do you even raise a kid?” A parenting fantasy where the protagonist raises Seere to become the strongest Demon King.(Source: KakaoPage, translated)
