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!!

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?!

The end of the year is drawing close as well. When Tohru plays the lottery at the shopping district, she wins a prize--a kotatsu, not the hot springs trip. Once they finally join Miss Kobayashi in the kotatsu, the dragons start lazing around... The kotatsu ruins not only humans, but dragons too. That relaxed, lazy mood is how Miss Kobayashi's family ends up spending their end of the year and the new year. Their peaceful days off pass by uneventfully. Meanwhile, Tohru and Kanna also change into kimono for their first shrine visit of the year--?!

The self-proclaimed ultimate maid Tohru storms into a new maid cafe opening up soon with a sense of rivalry. However, when she returns she says, "Somehow I've ended up working there!" As they live out such typical days in their lives, she and Miss Kobayashi learn from the news that someone has destroyed the mountain where they met.

It all started with a single statement from Elma--"I demand improved worker conditions!" The company Miss Kobayashi and the others work at is very close to being exploitative, and Elma finally realizes their situation is wrong and rises up against it. Miss Kobayashi assumes it's impossible to improve their working conditions, but the dragon's energy and spirit were far greater than she imagined...

After having a fight with Miss Kobayashi, Kanna runs away from home. Since she doesn't want to go home she flies across the ocean to somewhere brighter where the sun's still out. Kanna lands on the continent she happens to find during her flight, putting her in New York, the city that never sleeps.
