In this fic, it'll be similar to that of Reverse Rebirth from Kingdom Hearts: Chain of Memories and its remake, so it'll focus mainly around Riku and Naminé. It'll feature some worlds that Sora and Kairi might have been to before, but at the same time, there would be some flashbacks from the actual Pokémon episodes, but you'll have to wait and see what it'll be.

Also, Pokémon belongs to Nintendo and Game Freak as Kingdom Hearts belongs to Disney and Square Enix.

Enjoy.

Riku has taken a dangerous step into darkness as he used it as an act of revenge against a ruthless Pokémon Hunter calling herself J when she has stolen his Eevee from him.

Though Riku got Eevee back, but Rei Sakura has placed Riku on probation to get his emotions and the darkness under control, but she grew increasingly worried about Riku's well-being, so she sends Riku on his own mission and is accompanied by Naminé and his Pokémon.

But the evil Count Ernesh isn't willing to let Riku slip through his clutches that easily, so he sends his apprentice and Riku's younger sister Kanako after him.

But will Riku be able to control the darkness he holds within himself or will it consume him and become like Master Xehanort? That is what we will find out.
