Within the ruined shell of a city that once thrived, only the thrum of a motorcycle pierces the frigid winter hush. Its riders, Chito and Yuuri, are the sole survivors left in the shattered metropolis. Digging through abandoned military outposts for nourishment and salvage, the two girls wander the desolate plains and muse about the former world to occupy their hours. Chito and Yuuri each occasionally wrestle with impending isolation, yet when they share the burden of being the last two humans, it feels somewhat more tolerable. Between Yuuri's awkward enthusiasm and Chito's serene steadiness, their bleak days lighten with marksmanship drills, fresh volumes, and snowball skirmishes across the frozen arena. Against a backdrop of bleak terrain and empty structures, Shoujo Shuumatsu Ryokou narrates an uplifting saga of two girls seeking hope amid a dying realm for the wandering souls who wander beyond hope today.
