Pokemon x The Hero is Overpowered but Overly Cautious
I've got an idea for a Crossover AU fanfiction between Pokemon and the Light Novel "The Hero is Overpowered but Overly Cautious" where Seiya ends up in the world of "Pokemon".
Ristarte disguises herself as a human and claims to be Seiya's girlfriend Rika (much to the confusion of the people who don't comprehend what she sees in him). And here the "It's funny because it's true" kind of comedy starts: His overly cautious behaviour makes him inter-regionally (in-)famous inside the world of Pokemon. People perceive him with skepticism, which turns into respect when they see that his eccentric personality make him an extremely competent Pokemon trainer.
Over time Cynthia, May and Lillie join him and some trainers like Brandon and Bede attempt to imitate Seiya's philosophy but fail hard.
During their journey, Cynthia, May and Lillie develop deeper feelings for Seiya (resulting in some kind of "slow-burn harem comedy" where they flirt with him and he doesn't notice it).
This causes a huge character development in Ristarte. At first, she reacts with jealousy and possesiveness, but the more time she spends with the trio, the more she becomes broody - contemplating, if her feelings for him are healthy and if he shouldn't be with one of them instead.
