Kazuko had met Kazuo in the middle school science lab and accidentally inhaled the fumes of his time travel formula, allowing her to timejump brief amounts of time. He erased her memory of him, and plans to do the same to Akari.Akari asks to say goodbye to Ryota, who does not know when she is going back to her time. Ryota bids Akari farewell in misunderstanding, as he is leaving for a day trip. He gives Akari the soundless movie film to keep. Akari realizes too late that Ryota is going on a bus that will famously crash off a cliff and kill all passengers, and rushes off to save him, but Kazuo stops her from changing the past and erases her memory of both himself and Ryota. ........
