[2] Natsuna Keyaki, a post-secondary student living in Tokyo, is contacted by her old friend Itsuki Kusunoki from Kumamoto through an on-line game platform, who she hasn't heard from for 4 years.

Whilst Izumi's friends turn out not to know who Itsuki is, Natsuna stays and has some fun with them, smashing watermelons and accidentally falling into the canal.

Natsuna is dropped off at her hotel room by the Chibas, and whilst sleeping, dreams of her drawing together with Itsuki in their in-game bodies.

The dream quickly turns into a nightmare as Itsuki crumbles and the earthquakes strike, and Natsuna awakes and cries.

Natsuna heads back to the Chibas' place to contemplate this along with Izumi, when the latter tells her that she's romantically interested in Masayoshi.

As she rides the bus there, Natsuna contemplates how she just stopped communicating with Itsuki shortly after the earthquakes; rationalising she was busy with school after telling her she was well.

Natsuna tells her about a promise they'd made together to draw Kumamoto landscapes, and the girl says Itsuki is in France studying art, and that she'd be back by summer's end.

As she checks in for her flight, Natsuna realises that the girl at the wharf must have been Itsuki, and runs out of the airport - getting Masayoshi to drive her back towards Sakitsu.

Itsuki says that she hurt her hand in the earthquake, and couldn't resume drawing until she'd come to Sakitsu to convalesce at her grandmother's place.
