The high school team debuted in New Prince of Tennis as members of the elite U-17 tennis camp for the All-Japan team. These high schoolers are noted as the top youth tennis players in Japan. Entry into the camp is only possible through invitation, and 50 middle schoolers from Prince of Tennis were invited to further develop their skills. The first string (composed of the top 20 members out of the 250 member pool, now 300 after the middle schoolers joined) regularly travels abroad to compete against other high school teams from other countries (also composed of the best of those countries). A vast majority of the high schoolers on the second string are extremely arrogant, looking down on the middle schoolers the moment they walked in the gates. However, the same majority quickly proved to be inferior to the middle schoolers in terms of skill.
