Two young girls, Yoko and Airi, travel through an empty post-apocalyptic world.

They photograph the scenery of famous places all to themselves and camp out in towns full of nature.

The two of them ride and travel on a Serow off-road motorbike together,
experiencing a never-before-felt freedom in travel with no traffic and no traffic lights.

With the Serow bike, they embark on a journey around a now-destroyed Japan;
a unique story about touring on a bike comes to life as an anime series!

The world's over now, so let’s hop on a bike and go on a journey!
