Reigen tries to persuade a client that a curse from porn sites caused his heavy stiff shoulder, but a quick demonstration of his massage skills wins the man over much more easily. Later, over takoyaki, Mob wonders aloud if there is something better he could be doing with his time than working for him. Reigen internally panics before reassuring him that continuing to do so and slacking off is perfectly okay.
Cut to Takenaka, a student in the Telepathy Club at Mob's school, quitting in a huff. President Tome Kurata and the other club members freak out—they no longer have enough members to keep their official status. Student Council Vice President Tokugawa swoops in mere minutes later to send them packing. Over their objections, he offers them a deal: find a new member in less than two days or be dissolved.
Kurata and company prowl the halls asking every student they see to join, but are soundly and repeatedly rebuffed. Club member Inukawa, an early childhood acquaintance of Mob's, gets an idea. He runs off to find Mob—the last member of the 'going-home club'—but Mob actually has plans after school: an exorcism job? Inukawa and the incredulous Kurata plead with him to join anyway. Kurata mounts the strongest defense, even picking a fight with Mob's boss over the phone, but in vain.
The exorcism Mob is headed to after class? It's at a girls' private high school. Reigen couldn't get permission for them to enter legitimately, so they're in drag. Mob is not happy about this. He's even more upset that police stop Reigen at the school gates but allow him in. Nervous about the possibility of detection and performing an exorcism solo for paying clients, Drag!Mob makes his way to the roof to meet up with them.
Reigen's customers, openly doubtful of Mob's abilities, explain the situation: A ghost has been scaring students and even stealing their undergarments. The two girls lead him around the school to find the culprit. Finally, the teenager locates him in the gym where the basketball team is practicing, sealing the spirit inside. When he attempts to take a hostage, Mob summarily exorcises him to cheers and applause: a job well done. The vanquished specter then asks the boy a question he can't answer before fading into nothingness. That night, Ritsu asks the obviously shaken Mob if he is troubled and wants to talk. Mob declines.
Just as Kurata thrusts a club admission form under his nose, Tokugawa bursts in with five heavily muscled kids in tow who need the room—the newly-incorporated Body Improvement Club. Kurata protests again: but her club can now meet their member quota! The Student Council Veep earnestly urges Mob to reconsider. Mob is... rather unaccustomed to considering his own wants and emotionally spirals before remembering what's important to him. Will he join the slackers or choose the path of self-improvement?
Tropes in this episode include:
- Art Shift: It's a staple of the comedy in this show. Too many examples to count but salient examples include:
- The Telepathy Club members' heads swell, their skin colors shift, and they increasingly resemble zombies in their desperate search for a fifth member.
- The delinquents Mob encounters before meeting with Reigen's clients. One of the punk girls' heads grows to enormous size and emits steam as she yells at him.
- Mob himself, on being pressed to think about what he wants for a change.
- Armor-Piercing Question:
- Several from Tokugawa, as he encourages Mob to think for himself and decide what he wants.
- And one from the ghost Mob exorcises. He compares himself unfavorably to the overpowered teenager, and asks with his last wisp of existence if Mob is 'living every day to the fullest'.
- Bait-and-Switch: The entire episode acts as a setup for one of these:
- We spend a fair amount of time with the Telepathy Club, their struggle to avoid disbandment by the Student Council, and their attempt to get Mob to join them. When Mob decides to join a school club, a scene of the Telepathy Club's ecstasy over their new member cuts to the teenager declaring membership in the newly-introduced Body Improvement Club instead.
- Brutal Honesty: On both Reigen's and Mob's parts: Reigen for pointing out that Mob doesn't usually initiate conversations and Mob for suggesting that he is 'wasting his youth' working as Reigen's part-time assistant.
- Body Wipe: As Reigen flexes all his theatrical wiles to convince his client of a supernatural cause for his shoulder pain, his pupil swallows the screen... before cutting straight to the opening titles.
- Crocodile Tears: Kurata pretends to cry to manipulate Mob into joining her club. It almost works.
- Disguised in Drag: The only way Mob and Reigen can meet with clients Chihiro and Mari at school. Mob emphatically disapproves.
- Extreme Doormat:
- Mob's inability to say no outright to the Telepathy Club starts a war of words over him between Kurata and Reigen.
- Tokugawa asking Mob what he actually wants to do gives the kid an existential crisis.
- Gilligan Cut: A two-cut version. Reigen advises Mob to turn down things he doesn't want to do. The next cut establishes—using a shot of Reigen's bouncing ponytail and onlookers' disgust—that the pair are crossdressing, and that Mob really, really doesn't want to do this. The second cut pans up to confirm the drag.
- Innocently Insensitive:
- Is it ever kind to imply to a person's face that time spent with them is wasted? Reigen doesn't take offense at Mob's statement though.
- Honorable mention to Inukawa for dragging his acquaintance Mob to meet the Telepathy Club and introducing him to them as an 'all-round bum'. Mob agrees with him.
- Hypocrite Has a Point: Reigen is himself using Mob, but he intervenes to prevent another person from doing so. He is actually right about Kurata's motivations and their implications for Mob's future, even though his own are similar.
- Not So Stoic:
- Mob is visibly shaken at his clients openly ridiculing him and at Chihiro's suggestion that he is unreliable.
- He blushes hard over the basketball team's cheers of admiration and the clients' gratitude. At least one of the team members asks if he wants to go home with her that day. It's heartwarming to see.
- Not What It Looks Like: Thanks to Reigen's Paper-Thin Disguise, bystanders and the policeman keeping watch outside the girls' private high school assume he's a potential pervert.
- Panty Thief / Peeping Tom / Perverted Sniffing: All apply to this episode's Monster of the Week, the spirit of a young man who gets off on stealing high school girls' underwear.
- The Pirates Who Don't Do Anything: Subverted; the Telepathy Club. Kurata is the only member actually interested in telepathy and communicating with alien life; the other members use it as an opportunity to snack on the school's dime, nap, or play video games. In the end, they are formally dissolved, but the Body Improvement Club lets them continue to use the space to hang out.
- Troubled Fetal Position: Mob in the bath after he exorcises the spirit haunting the girls' private high school. The ghoul gave him much to think about.
- Valley Girl: In the English dub, Reigen gives himself this accent when Disguised in Drag.
- Younger Than They Look: The Body Improvement Club. One would be forgiven for mistaking the young teens for grown men; it's implied that this is how Mob sees them.
