Josei Shonan (2nd Year)
Higuchi Chieko (Japanese)
Tanaka Youhei is a regular that only appears in the anime as a Josei Shounan regular and is the elder of the Tanaka twins, in which they prefer to be called a Unit. He has superior hearing ability and body vision, making he and his twin the perfect doubles team. However, they tend to be overconfident and underestimate their opponents.
He is often mistaken as a girl due to his appearance. He has short purple/pink hair with a high-lighted stripe on his bangs. He also has turquois eyes, is relatively short (around Ryoma's height) and wears a black choker around his neck.
- Yōhei and his brother only exist in the anime. In the manga, he is not on the Josei Shonan's regular team sheet.
- In the movie, Atobe's Gift, he and his younger brother, Kōhei Tanaka, are shown to possess an certain level of vocal musical talent as they held a concert together at the Super Tennis Festival.
