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?!

Saikawa visits Miss Kobayashi's home to play. However, there's a girl that's unfamiliar to her (Ilulu)... Even after inviting her to join their games, Ilulu coldly refuses. Then Lucoa happens to stop by and she notices Ilulu's feelings as she tries to avoid them, so she makes an effort to help the dragon out.

Elma and Tohru snarl at each other every time they meet in the shopping district. Miss Kobayashi is exasperated at that typical scene, but they mention it wasn't like that when they first met. Even though they get along like oil and water now, their first encounter took place long, long ago. It happened way back when Tohru was traveling by herself through the other world...

Two suspicious figures appear in a dark alley under the cover of night. An unsettling air hangs over their secret exchange. "What do you need, asking me to come here?" asks the perverted woman with two horns. "Lend me your power," answers the melancholic man in a butler uniform. And so the most sinister and awful tag team begins to take action.

Miss Kobayashi's hips have seriously started hurting. She buys up a bunch of health products to try and improve it, but she hardly uses any of them... Even Tohru loses her patience and tries to get her to eat tail meat, but she sadly refuses. Tohru then begins her search for what Miss Kobayashi considers a "typical remedy."
