Fuuka - Season 1 Episode 5 One of Us!
Overview: The new school term has begun, and Yuu's band has begun to practice in earnest, but bassist Yuu and vocalist/guitarist Fuuka are complete beginners. Nachi isn't much better as a drummer, and they attempt to recruit a senpai from their school, Sara Iwami, to take over on guitar. She's cold to them at first, but a revelation about Yuu brings her around.
