Ayumu gets Haruna and Eucliwood to help him study for an exam so he doesn't have to go to summer school. Following the exam, as Ayumu searches for Haruna, who sensed a Horse Megalo during the exam, he gets a call from Dai-sensei asking him to hold onto a certain something. When Ayumu enters the battle, he is double-teamed by a group of Jellyfish Megalo but is rescued by a ramen delivery girl who manages to defeat the Megalo with her tonkotsu soup. She is revealed to be a vampire ninja named Maelstrom. When Haruna gets annoyed with Ayumu ignoring her, she pushes Ayumu onto Maelstrom, making him kiss her accidentally. Maelstrom later takes Ayumu and Seraphim to her secret base and explains about how they use a machine to rain tonkotsu soup on hordes of Megalos. After they leave, Seraphim reveals that, because of the kiss earlier, according to the ninja code, Ayumu and Maelstrom are now considered married. Afterwards, Ayumu and the girls celebrate Tanabata. The next day at school, Maelstrom, who is known as Yuki Yoshida in school, declares her married status to Ayumu's entire class. Ayumu also discovers that the item Dai-sensei wanted him to hold onto are x-ray glasses.
