There's one where the MC discovers a PC game where they can choose how many characters to raise. The MC chooses two characters to raise for a few years, but within the game, the characters worship the players as gods, and once the god's "protégés" reach high school, the gods "descend." They're basically summoned to that world. The MC was the player who donated the most to the game and gained additional powers that other players don't have. There are dungeons they have to clear, and so on.

P.S. I don't remember the name, but if anyone knows it, I'd appreciate it if you could share it with me. I'm desperately looking for it.
