Mmm, ficlove. And it's so very Ryouma to do what Tezuka wants him to do, because, well, he's Tezuka-buchou, regardless of what Ryouma personally thinks of the situation. It's also oddly Tezuka to make sure that Ryouma doesn't suffer too much for doing it. Well, suffer too much or beat someone to death with his racquet, which is the other option, and the one that I would opt for.

...on a note completely unrelated to the fic, you said "Kevin Smith" and my initial reaction was, "...Silent Bob plays tennis?" But that's just because these associations tend to form.
