“Holiday Caprice”
“Kyūjitsu no Kisōkyoku ~caprice~” (休日の奇想曲 〜caprice〜)

Yuichi reminisces about events of the past seven years ago concerning his first meeting with Ayu. Nayuki makes Yuichi return to school to retrieve her school notes she borrowed to him, and as he is leaving the premises, he runs into a third-year student, Mai Kawasumi, who is wielding a sword.
