If one day, the contestants of the Concave and Concave Contest start to learn.
Blanche: Put me down! This is not a car for a bump contest!
＊Emphasis added: Since the world line of this work is imaginary, it is not the world of concave and convex itself. In order to fit the background, the settings will also be changed. It would be too troublesome to list them one by one. If you don't understand anything, you can ask me in the comments (Feelings)
