Yuuka Yashiro

Yuuka Yashiro is a friend of Miina Miyafuji from middle school. She appears at the end of episode 9 recognizing Miina and recalling the history that Miina has been trying to put behind her. Miina comes to terms with it in episode 10, and Yuuka is seen again at the beginning of episode 11. In the light novel, this section of the Please Twins! story is entirely rewritten and Yuuka is omitted, replaced with Yukiko Kachofugetsuin, Karen's rival in playing the piano.
