Rentarou is investigating rumors of a mystery masseuse who has been massaging the school's sports teams. A scream from the tennis court brings him to a scene of girls collapsed on the ground. Standing in the pile of athletes is a younger girl who triggers a ZING!! when Rentarou draws near. The collapsed athletes tell him that she massaged them, with the girl confirming her identity as the mystery masseuse before introducing herself as third year junior high student Momiji Momi. Surprised by the quick introduction and the quality of her massages, Rentarou offers to help escort the tennis athletes to their club room, though they get sidetracked by Rentarou's disturbances at Momiji groping the girls' chests in a fetishistic manner.
After all the girls are in their club room, Momiji offers to give Rentarou a massage. While surprised at how stiff his body is, (owing to the work Rentarou does tending to his girlfriends and scoping out dating spots) she's able to make quick work of his body. The next day, she finds herself thinking about Rentarou and wanting to massage him again. When the two cross paths again, Rentarou's body has grown stiff again. She again makes quick work of his body, and in class the next day, realizes she's in love with him, unaware that one of her classmates is dating Rentarou.
After massaging "Astro Boy" a third time, Momiji demands an explanation for how his body keeps getting stiff every day. Rentarou explains that he was tensing up his body so that Momiji could practice massaging men, and two days earlier, he started helping Nozawa-sensei draw the manga; owing to the huge number of characters she was expected to draw, her job is the epitome of difficult. Touched by his efforts to appease her desires, Momiji confesses to Rentarou before she and Rentarou head off to provide a massage for Nozawa-sensei.
Tropes:
- Creator Cameo: The manga's illustrator, Nozawa-sensei, appears in the manga itself in this chapter. (With pixellation applied to protect her privacy.)
- LOL, 69: This chapter introduces a girlfriend with a fetish for groping women.
- Shout-Out:
- Momiji explains her ability to tell if someone's fatigued even through their clothes as being a skill that develops naturally with massage experience, just like Goku's ability to judge how strong someone is by looking at them, to which Rentarou's reaction is "You have an internal scouter?!".
- Momiji also keeps comparing Rentarou's body to Astro Boy's, due to how stiff it is, and wonders if he's being forced into slave labor in an underground facility. Rentarou shoots it down, saying "This isn't Kaiji.".
- Momiji compares her full name to that of Nobi Nobita.
- Momiji has a pillow of Nami to stuff her face in.
