Hayate is a ninja and so he is properly trained to land some hits in real sneaky like no matter where his opponent is. That won’t be enough to stop Ryoma in his tracks though. Ryoma can move with incredible speed and his striking power is pretty dynamic. Hayate’s sword would shatter as soon as the first tennis ball gets thrown over. He just isn’t ready for the Prince of Tennis! Ryoma wins.

I’ll be frank. Hayate minces Ryoma, for he can kill. A tennis ball is not enough to make him fall.
It’s no ordinary tennis ball though. Ryoma uses it to take people down on the regular.
By the way I don’t have any more matches listed from you in the vault in case you were waiting to send more.
