Yuuki Aoyama

She is one of the twin daughters of a hairdresser, excels at singing and dancing, and a member of a famous idol group. She returned to Hinano for a certain reason. She likes going to the karaoke by herself. She has low self-esteem, sometimes descending into a "world of paranoia" (as Genki calls it) in which she believes people hate her even if they're actually being friendly and kind. After being convinced to join the Cheer Fruits, she leads the performance of the theme song and plays Sein Blue, who hails from Hinano's sister city of Cuernavaca, in the state of Morelos, in Mexico.
