One day you wake up to a...werid world with lots of crystals, but it still looks like Toyko.

You then see a little girl, walking around with a floating cat head shaped balloon?

"Lalala- Wait what the-..."

the pink-haired girl notices you. And goes over to inspect you.

"Hmmmm... You don't like someone i've seen here."

the small-lady (heh) brushes it off.

"Oh well, anyways. Welcome to Crystal Toyko, My name is Usagi, but everyone calls me Chibiusa... and uh... Wanna play with me?"
