A humorous, comedic crossover between [Pokemon] and [Genshin Impact].
After transmigrating to the Pokemon world, Lu Hayakawa loses both his parents when he is very young. His butler entrusts him to the care of his father's friend, Professor Oak.
When Lu Hayakawa turns ten and begins his journey, his original Souvenir System is devoured and merged with another System, becoming a Dual-World Souvenir System. It takes Lu Hayakawa to Teyvat. From then on, Teyvat has a Trainer, and the Pokemon world has a Trainer who plays with monsters.
A battle in the Pokemon world:
"Go, Marowak!"
Lu Hayakawa: "Go, Hilichurl!"
When he encounters the God of the Vortex in Teyvat:
Lu Hayakawa says, "Back when your uncle Lugia soloed Hoopa, you weren't even born yet!"
When he faces the corrupted little edgelord Marshadow and a horde of Pokemon, Lu can only say:
"Bro Kong, call for backup!!!"
