Amidst the ruins of a once-thriving city now abandoned and desolate, the only sound that pierces the frigid winter air is the roar of a motorbike. Chito and Yuuri, the last remaining survivors of the war-torn region, forage for nourishment and salvage spare parts from ancient military facilities, while reminiscing about the old world to while away the hours. Though the stillness occasionally feels suffocating, the burden of being among the final humans on Earth is shared, easing the weight. Guided by Yuuri's clumsy enthusiasm and Chito's stoic resolve, even the darkest days are brightened by marksmanship practice, fresh reads, and snowball battles within the arctic arena. Shoujo Shuumatsu Ryokou weaves an uplifting narrative of optimism in a barren and decaying world, as two brave girls embark on a quest to discover purpose and joy amid desolate wastelands and abandoned dwellings.
