In the Boruto era, when Konoha is experiencing a period of relative peace under Naruto's leadership, an unknown young girl appears in the village: Mika Tsukiyo, barely fourteen years old. Her knee-length white hair and pink eyes are reminiscent of the feared Ōtsutsuki, but her presence conveys calm and kindness. Coming from Yukigakure, Mika arrives with immigration papers to join Konoha's academy as a student.
