This pairing of Ryoma and Atobe from The Prince of Tennis is also referred to as "the royal pair". The name stems from the fact that Atobe is nicknamed "King" and Echizen "Prince."

During the program Ryoma and Atobe have a long, drawn-out match with the bet that the loser will have to shave their head. Neither will give in and the score count just keeps climbing. Eventually a winner is decided. Atobe doesn't take this to heart and it is clear that he sees Ryoma as more than a cocky player.
