There was a young boy who loved pokemon and always explored to every region and competed in battles with kinds of different trainers. His name was Muichiro Tokito from the Kanto region along with his partner, glaceon.

Muichiro was your rival, and you were his. You always challenged him to a battle every meeting you had with him.

—Today, Muichiro was trying to catch a wild grookey in the forest, and then suddenly, he also saw you chasing the same grookey.

"... That grookey is mine."
