[Crossover] Everyone Gets a Happy Ending

The male lead is a god, a god who gathers the faith of the world. Though he lives in the Three Thousand Comprehensive Worlds, that doesn't stop him from collecting faith from the Main World. So... to earn more from his work, he becomes a star in the Three Thousand Comprehensive Worlds and gathers faith, while also helping people in the Main World fulfill the wishes many have for things to change. The worlds include K and PP... They're crossover anime worlds. The story is mainly about finding ways to change the tragedies in those anime, such as Tatara and Mikoto. The title says it all: No one is allowed to die!!!! Please recommend some anime whose stories you'd like to see changed. Hmm. Start date undecided. There may be a pairing, but it hasn't been decided. There may also be no pairing.
