Bocchi recovers from her self-inflicted fever after a couple days, and while brushing her ahoge tells her little sister it’s important for “people like her” to attend class lest her classmates forget she exists. Her little sister says her sister is “a pain in her own ass” and she’s not wrong! That said, Bocchi is still feeling confident now that she’s made two friends, joined a band, and gotten a part-time job.
That confidence evaporates when yet again no one approaches her in class, and when she hears two girls engaging in band talk, she loudly yelps to get their attention. Not only do they know her name, but they seem open to hearing her out, but poor Bocchi can’t get any words out. She didn’t prepare adequately! So she retreats to a dark corner of the school to eat lunch in tears.
When she encounters Kita Ikuyo, a red-haired girl that everyone says is great at karaoke, Bocchi observes her from afar, but is too intimidated by how much of an extrovert the girl is to get any closer. When the girl notices her anyway and also knows her name, Bocchi once again can’t say any words—she can only beatbox!
When Ikuyo beatboxes back, Bocchi shouts an apology, bolts, then returns to her hiding spot to serenade us with a ballad of melancholy. However only we hear the lyrics; Ikuyo followed Bocchi there, heard her playing, and thinks she’s awesome!
Bocchi, unaccustomed to praise, laps it up like honey and instantly deems Ikuyo a good person. Bocchi finally manages to blurt out the reason she’s been wanting to approach Ikuyo, and Ikuyo tells her she’s sorry, but she can’t join her band. Bocchi assumes she’s the reason and makes up all kinds of things to make her bandmates sound cool as hell (and they look kinda like Panty & Stocking in her mental image!) … to no avail.
Ikuyo says she can’t join a band for the same reason she flaked out on the band she joined to be closer to her senpai: she can’t actually play the guitar. Hearing her say she thought the neck was “for decoration” astonishes Bocchi, but despite her inner voice telling her “say no girl!”, she agrees to teach Ikuyo how to play in between school, band, and work.
After texting Nijika and Ryou to bring lots of energy drinks and blast EDM when they next meet, Bocchi takes Ikuyo to Shimo-Kita, and ends up having Ikuyo lead the way, using her as a shield to avoid the stares of others (while actually attracting more staring in the process).
When Bocchi mentions STARRY, Nijika and Ryou, Ikuyo tries to back out, saying she can’t go back there, but Nijika and Ryou arrive, arms bursting with energy drinks, and she can no longer run away. Once inside, Bocchi can tell how uncomfortable Ikuyo seems and wants to say something nice, but Ryou beats her to it.
Ikuyo wants to make it up to Nijika and Ryou for ditching them, and Nijika’s sister suggests she work a shift with the others. No doubt recognizing her talent for public relations, Seika dresses Ikuyo up in a maid outfit and has her handle admissions and drink tickets.
Bocchi immediately starts feeling inadequate and redundant, “losing her identity” and turning into a mist that rises up the club stairs as Ryou looks on. A “Thanks for Watching!” card flashes as if to herald yet another premature end to the series, but she snaps out of it when she’s asked to show Ikuyo how to serve drinks.
Unfortunately, being watched makes Bocchi so nervous she burns herself with coffee. Ikuyo wraps her hand in a handkerchief, and Bocchi notices something about Ikuyo’s hand. When Ikuyo asks why Bocchi joined a band, Bocchi lies and says “world peace” because she’s self-conscious about having “impure” motives like wanting fame and popularity.
But then Ikuyo turns around and admits her motives are impure (too): she joined to be closer to her senpai, Ryou, whom she once watched performing on the streets and fell head-over-heels in love. Honestly, I can’t blame her; of the four leads, three are extremely high-strung, while Ryou’s never not an island of cool tranquility.
When the music’s over and the house lights are back up, Ikuyo prepares to depart from her first and only shift at STARRY. But even earlier, Bocchi had been building up the determination to say something to Ikuyo to make her stay. Unfortunately, her body moves before her mind can get all its ducks in a row, and she ends up tripping, ripping down a black curtain, and smacking her noggin on the wall.
While it’s not how she wanted to do it, it does keep Ikuyo there, if only because she’s concerned about Bocchi. She even gleans that Bocchi was going to try to say something to convince her it was okay to stay, but says she can’t join a band she already flaked out on once, especially when she can’t really play the guitar.
Bocchi tells Ikuyo that she ran away before the concert too, and threw herself in a trash can. But she also felt Ikuyo’s hands when she was treating her burn, and she felt the calluses one only gets by working their butt off practicing. That is all Bocchi needs to know that Ikuyo is committed enough to join, or rather re-join Kessoku Band.
Nijika and Ryou agree with Bocchi: Ikuyo should join them. They’re not even mad that she flaked out the first time, because if she hadn’t they wouldn’t have meet Bocchi! But the fact remains, Ikuyo’s guitar ignorance is such that she’d been practicing on a six-string bass all this time without knowing it, attributing the bomm-bomm sound it made to her being terrible.
Ryou buys her bass (and ending up broke and eating weeds) and lends her an actual guitar to practice with as Bocchi teaches her in STARRY’s back room. Ikuyo’s progress is slow and she’s easily frustrated and whines a lot, but Bocchi recognizes all of the ways she gets frustrated because that was her three years ago. Now she has the skills to not only play, but teach.
Bocchi was right about Ikuyo, she’s a very nice person. She’s so nice, she almost deprived herself of her dream of playing with her beloved senpai because she thought her misdeeds were too serious to be forgiven. But Bocchi, Nijika, and Ryou are also good kids, and knew the band would be better with her than without.
That Bocchi worked so hard in recruiting Ikuyo speaks to how she continues to make progress interacting with people. Her anxiety and myriad neuroses were likely remain a part of her for a good long time (if not forever) but she’s gradually learning that she, like everyone else, deserves a happy life and friends to rock out with.
