Kanna watched the elementary schoolers going to school with jealousy, so Miss Kobayashi decides to let Kanna attend elementary school. Miss Kobayashi, Tohru, and Kanna all set out to the shopping district in order to buy Kanna's school supplies, but Miss Kobayashi is overwhelmed by the modern stationery store recently built. On the other hand, both Tohru and Kanna are intrigued by their first sight of stationery stores. After they finally gather all the supplies she needs, it's time for Kanna to join the school!!

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?!

Kanna is invited to Saikawa's home. Since Saikawa's family has a maid too, they invite Miss Kobayashi and Tohru to join her. When a genuine maid, Josie, greets them, Miss Kobayashi gets excited. The two hit it off, chatting about maids. To top things off, Lucoa announces she's planning to live in this world too. She claims she was summoned by Shouta, a member of a mage family. Lucoa gets very touchy to try and get along with Shouta, but she goes overboard...

Miss Kobayashi and the others go to the beach. But Lucoa's immediately dragged off by one of the lifeguards for her overly skimpy swimsuit. After regrouping, they put sunscreen on each other, split a watermelon, go swimming together, and enjoy summer to the fullest. After the beach, it's comiket! Tohru and Miss Kobayashi both head for the otaku's battlefield, and even Tohru gets shivers from the incredible aura surrounding those otaku. While helping Takiya with his circle, Tohru's horns and wings are mistaken as cosplay?!

Kobayashi and Tohru challenge each other to a cook-off to decide who will make a lunchbox for Kanna's field trip, with Tohru ultimately getting disqualified for using an otherworldly fruit for dessert. Later that night, Tohru's rival from an opposing faction, Elma, comes to try and force Tohru to return home, but Tohru puts an abrupt end to their battle. Unable to return to her world, Elma begins working under Kobayashi at her company, prompting some jealousy from Tohru.

It's Kanna's sports festival. However, when she learns Miss Kobayashi is too busy at work to come, she sulks. Miss Kobayashi wonders why she'd want her to come so badly when she isn't Kanna's parent, but Kanna already views her as one. Even Takiya tells her, "You should decide based on if you want to go, not if you can go." Finally, the day of the sports festival arrives. As a dragon, Kanna should have overwhelming physical prowess, but...?!
