(Prince of Tennis) What Is This Supposed to Be?

This is basically a Super Mario transmigration trial run. Mm~~ It needs a tragic past, it needs clichés, it needs a prince, it needs~~~ lots and lots~~ Yin He: How did I end up drawing the 'best fortune'? U: There was no drawing lots. I just went off the rails, as usual! They say transmigration, but really, it's just borrowing a body and an identity. I don't know the plot... Actually, I'm not very good at writing characters whose stories I already know~~ I'll keep digging this huge hole~ It's not my fault I keep digging holes~ Let's fill the world with holes~~ Theme:
