Fujisaki Nadeshiko

Fujisaki Nadeshiko is a student in the same year as Amu and serves as Queen's Chair of the Guardians. When Amu rejected the offer to join the Guardians, Nadeshiko tries several tactics to convince Amu to join. The two become best friends and Nadeshiko looks over and supports Amu in her love life. However, before Amu and Nadeshiko enter the sixth grade, Nadeshiko leaves Seiyo Elementary for Europe to study dancing.

Nadeshiko is actually a boy named Fujisaki Nagihiko, called "Nagi" as a nickname by Amu and the girls. It is tradition in the Fujisaki family for males to be raised as females as part of their training so that they may play female roles in Japanese dance. Nagihiko's secret is known by his family, Kukai, Tadase, the school's principal Tsukasa Amakawa, and as of chapter 34, Rima. After Kairi leaves the Guardians, Nagihiko returns and is appointed as the interim Jack's Chair.
