I remember watching it as a child but don't remember the name of it.
It was in Cantonese possibly dubbed from a Japanese animation movie or show from the early 1990's.
I think it started out with a high school basketball player who in the middle of a game time freezes and he gets pulled into a fantasy world. In the fantasy world he has this icon that he can use to call for a creature that is linked to the icon. There are others in that world with that sort of icon and creatures linked to it as well.
At some point he gets sent back to the real world and resumes from the point in the game he was pulled out of but for some reason he still has the icon but its frozen and he's trying to get back to the fantasy world.
Kind of random but it keeps popping into my head every once in a while... would really love to find out what it is.
Thanks for the help.
