It's a hot day in the Sanzenin mansion, as Hayate is spraying water at the flowers. Nagi went outside as she was heading for school, then Hayate tells her that it's the beginning of their summer vacation, but Nagi knew that since she said that it was a joke. While grabbing the garden hose that Hayate was holding, Nagi sprayed at the flowers when she wants to spend her summer by playing video games, watching anime, making more mangas, and fool around to her heart's content. When Hayate was saying that Nagi must be happy about it, she looked forward to spend her day with Hayate, and then she sprayed a lot of water. At Hakuou Academy, Yukiji is spending her summer off eating squid and drinking beer, until Izumi, Miki, and Risa appeared from outside of the building and wants Yukiji to join them as they will catch the beetles, even if it means by force.

Meanwhile, when Maria is cleaning up the dishes, Hayate asked her about her ultimate attack as he explained what just happened when he was in school. Hayate wants to know if Maria can use her deadly attacks, although Maria doesn't want to talk about it; however, even Nagi wants to hear that. Maria said that ultimate attacks is never easy to learn, but Hayate is eager enough to master his ultimate attack right away and also wants to know if there is a book about the ultimate attack, so Maria leads the way to the Sanzenin library. Hayate found the books that are only reserved for Nagi, both on the shelves and on the floor, but they're just mangas, and video game guides, though Nagi was being mocked at. While Hayate is searching for the book of the ultimate attacks, Nagi decides to help him find it, when Maria is walking away, she saw the book about the ultimate attacks, Hayate and Nagi found the "other" book of the ultimate attacks, only that this book is for beginners. When Hayate questions about the "Sanzenin Secret Technique", Maria explained that the secret technique was used by the butler who used to work with Nagi before, named Akane Himegami. Then Klaus appeared from hiding in the book shelves, asking Hayate if he is interested in his ultimate attack, until Nagi tells Klaus to get back to work. Nagi then decides that she will train Hayate as he followed her, although she tripped and fell on the floor.

Outside of the mansion, Nagi begins by telling Hayate what is he going to do for his ultimate attack, while Tama appeared next to him. When Nagi is reading the instructions about those who were burned by the enemies, Hayate finds that easier said than done, even Tama agreed with that. Just when Nagi read the name of the next lesson, which says about being "lovey-dovey" with a special someone, she hides it from Hayate and starts running away while reading it alone. Without looking, Nagi falls from the cliff, until Hayate saves her when she lands on him. The book was nearly useless, but it still has some moves with a special power that Hayate will master his ultimate move during summer, and he will apparently do that for Hinagiku's sake. After Nagi heard what Hayate said about Hinagiku helping him more, she burned the book to ashes and hit him really hard on his head. While Maria is mopping the floor, Hayate asked her if she can teach him the move to calm Nagi down, though she said that it requires a lot of training, and that it will take a while for him to learn the ultimate move.

Later that evening, Maria tells Hayate that Nagi ran out of the house. Although the guards are searching for Nagi, Hayate is still worried about Nagi wandering all alone, and Maria thinks that he is the reason why she left, so he went to look for her. Elsewhere, Nagi is still mad about Hayate and thinks that Hinagiku cares about him more than her, which makes her angrier and she always wanted to be like Hinagiku, even in her thinking balloon showing Hinagiku in her Kendo suit. Then, Ayumu was walking with her bicycle while drinking her sodapop and thinks about what Hayate was doing inside the mansion, as well as confronting Nagi. Just then, Ayumu and Nagi confronted each other again. Hayate found Nagi with Ayumu while he was hiding, and Maria asked him about his relationship with Ayumu, in which he responded that he and Ayumu were just classmates. Nagi told Ayumu that she owns the mansion and that Hayate is working as her butler. When Nagi was walking away, Ayumu stops her and challenges her in a one-on-one match for Hayate, Nagi then accepted her challenge and their location for their fight is the karaoke box.

Since this is Nagi's first time being in a karaoke box, Ayumu ordered the drinks before the battle begins. When Hayate is still hiding, he paid to rent the karaoke box for him and Maria right in front of where Nagi and Ayumu are in there. Hayate tells Maria about the device that she was holding, and he said that it's for requesting any song. Hayate wants Maria to sing first, but since she was not ready yet, Hayate will be the first one to sing. While Hayate is singing his song, the next room shows Ayumu singing this anime's theme song off-key and finishes it when she winked. The result of Ayumu's singing says 35%, which she failed. Nagi is next to sing, while Ayumu thought Nagi will easily lose since it's still Nagi's first time being there. However, Ayumu thought wrong, because somehow Nagi is singing her song perfectly, as the narrator explained that Nagi had special lessons when she was little. After that, the results of Nagi's singing says 100%, which means that Nagi won. However, Ayumu doesn't give up and challenges Nagi for a rematch, but in the end, Nagi reigned victorious, as Ayumu paid the money. Then, the mansion guards found Nagi and came to pick her up, before she left, though, Ayumu tells Nagi that they will meet again in their next battle, and Nagi looks forward to defeat her again. Meanwhile, Hayate and Maria are still inside the karaoke box, with Maria singing her song. Elsewhere, at the Hakuou Academy, the trio were eating watermelons and staying in Yukiji's room. Finally, at Hinagiku's house, Hinagiku finished her book report and English essay. After the ending credits, this is Isumi's first time not being in this episode.
