Shokuyou Shikouhin Shoujo

A new infectious disease has caused humans to lose their sense of taste and smell. An edible luxury item called "Kimi" is developed that allows humans to sense taste and smell, and is eaten by all humans. A young boy named Sota cannot bear to see his beloved "Kimi" being eaten, so he takes him on the run, searching for clues to help restore the lost sense of taste and smell of humans.
