I’m in Ultraman, Collecting Monsters with Kaimey Cards

The protagonist, Ye Bai, is a man who really likes the Chemies from Gotchard. He bought some Chemy Cards online, but on his way back from picking up the package, he unexpectedly died and came to the Ultraman universe. The Chemy Cards he bought came with him, and he also received a System. (The protagonist will visit worlds outside the Ultraman universe, though those parts may be fairly short. The heroine has yet to be decided.) A newcomer here. Please be kind if it’s not to your taste.
