Squad One, otherwise known as Team Xen, was a team created by the academy after the graduation of genin Yoshika Shotai, Mizuki Kato, and Shikyo Hyuuga. The assigned jounin instructor, Xen, was assigned to them shortly afterwords. Although the team had complications at first, they soon learned to get along soon after Xen gave the three genin the bell test. Yoshika became the leader of the team after Xen went into semi-retirement, but joins the team sometimes for missions.
