A single off-road bike is cruising through famous touring spots. Gazing at Mount Fuji from Hakone, fishing at the Yokohama Bay Bridge, and heading towards the Tokyo Big Sight in Ariake. It seems like two girls are enjoying a tandem bike trip, but the surrounding scenery is terribly desolate――. In a world of desolation with no one around, two girls are riding their bike, starting an unusual touring comic! Even if the world ends, the bike journey will not end.
