Nana recalls the first time she meet the other Nana on the train while traveling to Tokyo.

Back in the present, Nana and Nana meet on the train to Tokyo. More detail is revealed around their meeting and events immediately after.

The two Nana's agree to share the apartment. Shoji and the others worry about Nana living alone with a total stranger.

Nana and Hachi get settled into their new apartment. Hachi begins her new job. That night, they receive a visitor from Nana's old band back home.

Several years in the future, the members of Blast plus Hachi and her daughter Satsuke meet each other again at Room 707 for the fireworks display, but strangely Nana is not present. Back in 2001, Hachi has cold feet about seeing Nobu again so Nana lies and tells her that he won't be present for the fireworks.
