In a post-apocalyptic world, Yoko and Airi travel freely on their electric bike, Serow; their destination this time is Hakone.

Their journey takes them from Hakone to Yokohama; they pass by collapsed bridges and see skyscrapers floating in the sea; as the two set out in search of food, an unexpected encounter awaits them.

Yoko and Airi get thirsty on their way to Tokyo, so they make a pit stop at Todoroki Ravine in Setagaya; after they quench their thirst, they walk around empty houses looking for food.

The girls visit Akihabara to find the source of Akiba Radio's transmission; as they explore the ruins of the former Electric Town, they come across butler and maid costumes, leading them to have some fun cosplaying.

They leave Akihabara and head over to Umihotaru, a rest stop on the way from Chiba; the girls run into trouble with the Serow as they struggle to ride it across the expansive wetlands of Nagareyama.

Two young girls, Yoko and Airi, travel through the empty world of post-apocalyptic Japan; they photograph the scenery of famous places and camp out in towns overtaken by nature.
