Celebrating 20 years of Ninja High School! Tennis prodigy Pete is unmatched in his skill at the game — a true Monarch of Tennis, even in a town full of ninja, demons, catgirls, and superpowered beings. Now he's being pushed into entering Quagmire High's elite tennis club by his former-tennis-star father, but Pete wants nothing to do with it. Instead, his goal is to wash dishes in every state of the country, so he takes a busboy job at the Sakura Inn! Can a team of cocky ninjas get Pete to enjoy his specialty sport, or will he deny his talent to become the world's greatest dishwasher?
