Hiyori Kuuki is troubled by her lack of presence, to the point that Mao Chanoki, who was in the same class as her from kindergarten to high school , doesn't even remember her face or name. One day, Hiyori gets a cramp in her leg during swimming class and nearly drowns, but because of her lack of presence, no one comes to her rescue. Just as she is about to give up hope, a mysterious girl named Dwarf-chan suddenly appears and saves her life.

After hearing about Dwarf-chan from Mao, Hiyori is taken by Mao to observe club activities , and ends up joining the Handicrafts Club (which is actually a cosplay club disguised as a crafts club) to which Dwarf-chan belongs.
