Kanna starts living with Tohru and Miss Kobayashi. While the livelier residence is nice, sharing a tiny apartment with three people becomes cramped. So Miss Kobayashi decides to move. She winds up inviting Takiya to her new apartment for a party, but Tohru also invites her dragon friends, Fafnir, who lives in a cave, and Lucoa, who's lived in this world since ancient times, to visit their new home.

Tohru's finally gotten the hang of her maid duties. Suddenly interested in what Miss Kobayashi does at work, she heads out to observe. There she watches how everyone relies on Miss Kobayashi and falls for her again. However, there's also a boss being mean to Miss Kobayashi, which makes Tohru very angry... Out on the town she runs into Fafnir from the other world. Since he says he'll be living in this world too, Tohru winds up helping him find a place to live?!
