Yeah, in fact in the very first episode Paruko mentioned that her buddy Martian UFO, Takosuke is from Hero World and the Card Castle manager also has a buddy from Hero called Superspace Robo Galaxy Demon.

And then there's still Legend World, which will be based off of mythologies from around the world.
