I'm not that impressive. [there's a cartoonish 'poof!' noise as he changes back into his regular self, a matching cartoon leaf drifting onto his head for a moment before it, too, disappears] I'm sure you'll be able to come up with something just as impressive if you practice enough, Prisma-chan.

We just improve at our own pace, that's all. So don't feel too discouraged.
