It’s not just Dungeon Meshi that bothers me. As one example, Darwin Carmichael Is Going to Hell ends with Darwin in heaven, but a character I liked just as much as him went to hell and will never stop suffering there for all eternity. There’s no hint the heaven and hell system could possibly end, and this is just something I’m supposed to accept along the way to the happy ending. Or that gay romance about the god of trash collectors. The main character is a proto-Utilitarian in a setting where Utilitarians are ontologically impossible, because your happiness is determined by unchangeable fate, and the only way to make your life better is to steal someone else’s fate and make them miserable. The main character never gives up trying to make the world better, but it’s unclear in the end what a better world could possibly look like, and I’m supposed to accept that because he got a BF and that’s a happy ending.
