Ryouma and Tezuka have a mild clash of wills, over which Ryouma gets rather frustrated.
Note: This particular story really came out of my personal opinion that the whole affair with Kevin Smith in the anime was rather inconsistent with the way Ryouma and Tezuka normally behave.
Ryouma could hear the mocking undertone perfectly well, and stifled a grin. It wasn’t quite time to grin at this one, yet. Not until Ryouma had him on the court.
