The protagonist ends up possessed inside the training simulation game “Evil Queen Maker.” They’d painstakingly raised their favorite character, only for the final boss to snatch her away as his bride in the ending. Furious, they send a long complaint about that ending… and get a reply: “Then you try making a better ending yourself.” Next thing they know, they’ve woken up inside the game as the “Demon Lord’s Mentor.” To escape this world, they have to raise the demon lord and see the game through to its ending. The problem? The demon lord they’re supposed to train, Seere, is only seven years old and the weakest existence in the entire setting. As war and intrigue swirl around them, the more Seere grows, the more she worries about how to win the attention and affection of her teacher, Nähn. “How are you even supposed to raise a kid?” Thus begins a “child‑rearing” fantasy about a former player who must turn a frail, clingy little girl into the strongest demon lord of all.
