I'm in a crossover anime world, and I've been transported to Hogwarts twice.

They traveled through time, but not just to one world.
When I'm awake, I'm in a crossover anime world, but when I'm dreaming, I'm in the Harry Potter world.
But that's not the most outrageous part.
What's absurd is that Gaia, the counterforce in this crossover anime world, likes to randomly pick up things in the World Ocean.
In order to prevent the everyday anime crossover world from being disrupted, Genichi Hanyu reluctantly picked up his wand to clean up Gaia's mess.
From the T-virus to the Kabane, to the ghouls, Gastrea, and later the Titans, they don't care about the lives of humans at all, do they?
Gaia, you really only think about yourself.
