: 27, 2002
Due to their recent victories, spies from other schools begin to observe Seigaku's training. When they catch two of the spies spying on them even after school hours, Momoshiro and Ryoma teach the two of them a lesson in a doubles match. When the two spies are only able to score one point against them, they decide to practice their tennis, instead of spying on others.
