“A Forgotten Partita”
“Kioku no nai Kumikyoku ~partita~” (記憶のない組曲 〜partita〜)

Bringing the girl that attacked him home, Yuichi finds out she has amnesia and it quickly becomes apparent that the only thing she is able to remember is that she has a grudge against him. Despite Yuichi wanting to hand her over to the police, Akiko lets the girl stay, and as she begins to stay longer, she recalls her name being Makoto Sawatari. At school, Yuichi sees the same first-year student from the day before standing in the courtyard; she introduces herself as Shiori.
