Following a catastrophic event that has brought the world to a state of ruin, the remaining human population lives out their final days in peaceful seclusion. Among them is Alpha Hatsuseno, an android who spends her days working at a scarcely visited café on the outskirts of Yokohama. She patiently awaits the return of her owner, while living out a quiet existence. One day, Kokone Takatsu, another android, arrives at the café with a package from Alpha's owner. Inside is a camera, gifted to Alpha so that she can cherish the memories of her surroundings through photography. Yokohama Kaidashi Kikou is a slow-paced and introspective anime that follows the journey of Alpha, as she captures the beauty of her surroundings and cherishes the moments that she shares with those she encounters, all amidst an atmosphere of gentle calmness.
