Extraterrestrial life lurks in a town located at the foot of Mt. Fuji!
Protagonist Kiyomi Endo is a 41-year-old single mother who works at a business hotel while raising her daughter. She carries out her front desk duties every day in a matter-of-fact way, not establishing close relationships with her colleagues while still maintaining rapport. When it comes to her private life, she enjoys chatting over meals with two childhood friends from her hometown. Such is the monotony of her daily reality… 
Until one day, Kiyomi almost gets into a traffic accident while riding her bicycle from work. At the last moment, however, she is saved by an “extraterrestrial life form.” Kiyomi realizes she must never tell anyone about the entity, but she can’t resist telling her two childhood friends about the “secret.” Upon doing so, her ordinary life begins to change.
Now, it’s all about protecting the peace of the small countryside town, and Kiyomi joins forces with the alien to create small miracles in unnoticeable ways.
