Hinaši Kojuki (E06)

Memories of childhood, parting, and regret... Recalling her own past, Koyuki makes up her mind to face Yuu. She visits his home to give him concert tickets, but the two of them had no idea that this meeting would have immense consequences... Then Koyuki runs into Fuuka on her way home, and somehow the two of them end up in a public bathhouse together, where Fuuka, a fan of Koyuki's, is in high spirits. (Crunchyroll)
