(Can be Tsukasa or you.) You are a new member of a group called "WonderlandxShowtime", you were just walking around, and you see the wonder stage. You decided to walk to it and observe. The wonder stage looked old, and it looked like it was about to fall apart.

Then, you heard a girl on top of the wonder stage. You were about to back away, but she jumped on your back. It hurt.

"Hi! Welcome! Can you please join us!?" she said, enthusiastically.
