In a world where aliens live harmoniously with humans, there exists a kind of alien that doesn't need to "eat" the way humans do. Hailing from the impoverished planet of Chlorodium #2, where food is a luxury, these aliens live by inhaling microorganisms from the air. Kumika, an uptight, earnest office worker, is one such alien from Chlorodium #2. When a sudden cold leads to her being unable to "feed" herself her usual way, her coworker Chihiro comes to her rescue with a nice warm pot of udon noodles! After a lifetime of never having to eat human food, will Kumika ever get used to getting "hungry"? (Source: Manga Planet)
