A university student called Natsuna loses contact with her old friend Itsuki when the online game they both play suddenly closes down. Natsuna doesn't have Itsuki's email address or phone number. She thinks Itsuki lives in Kumamoto, but that information's four years old. Furthermore, Kumamoto's right on the toe of Japan's main island chain, about 880 km away from Tokyo, where Natsuna lives. It would take about fourteen hours to drive there.
Natsuna blows her savings and gets on a plane. What she hasn't considered, though, is that Kumamoto had some famous earthquakes in 2016. When she reaches Itsuki's house, it's just empty ground covered in bits of rubble and trashed house.
The rest of the show is Natsuna's search for Itsuki. It's nice. She makes some friends, including a junior high school student called Izumi who says annoyingly stupid things to a local cop and probably thinks she's flirting with him. (Teenage girl in love. Brain disengaged. It happens.) The locals are pleasant, but usually can't help. Natsuna keeps going, though.
It's a brief sneeze of a series, obviously, especially since a quarter of each episode is the end credits. If you fast-forward through those, it barely lasts half an hour. It is, though, modestly charming. It was also commissioned by the Kumamoto Prefectural Government to promote the prefecture's recovery effort from those earthquakes. Fair enough.
"Thanks for all your support. Kumamoto will strive towards rebuilding a better future. Kumamoto Prefecture."
