The bright colors and dark themes continue to intermesh as the third girl of the series is introduced. Kawai Rika’s ash-blonde hair is set off by a hot pink highlight and a magenta-and-purple jacket. Like Ai, she has a statue of someone she’s trying to save, though she makes a point to tell her she’s fat and ugly and her palm sweaty. When Ai meets her at the egg gachapon, Rika is on the ground, holding her ribs, but soon recovers miraculously.
After commenting on Ai’s heterochromia, and promptly asks for some spare change. Aka and Ura-Aka, always seated around a game of go, aren’t concerned with the injuries the girls endure; it’s part of the job. Ai’s excitement to meet a new egg heroine quickly shifts to bemusement, as her interaction with Rika feels like a “one-girl handshake event”, as Ai puts it to Neiru, with whom she’s now texting on the regular.
Between barging in on Ai’s visit with Neiru, always making sure people know her name is Kawai because she’s so darn cute, calling the doctor hot, labeling Neiru a tsundere, and most distressingly eating up all the kiwi, Rika creates the impression of a superficial, shameless, self-involved brat. Nevertheless, she keeps following Ai around, inviting herself over to her house (causing Ai’s counselor Sawaki—whom Rika also calls hot—to leave) and unilaterally deciding to sleep over.
When Ai tells her about why she’s currently a shut-in, Rika immediately jumps to the conclusion Ai is seeking attention from the hot Sawaki. Then Ai tells her about Koito, then asks about the person Rika is trying to save. Rika makes clear the “ugly fatty” Chiemi isn’t her friend, but her fan, and also refers to her as a patron and a wallet. Ai is more or less appalled.
As Rika bathes we see scars on her arm from cutting, which she’s promised to stop. It was clear she was using a veneer of carefree bravado to hide deeper issues, but the scars confirm it without anyone saying a word. She says everyone’s the same in that when you “scratch the surface” they’re all “slimy”—something you could also say of an egg. Neiru texts Ai to be careful with Rika, warning that “junior idol could mean bedroom stuff.” That Ai earnestly asks “like pillow fights?” really says it all about Ai’s sheltered existence.
Ai dreams of a memory of her walking in on Koito crying while in Sawaki’s arms, adding a fresh dimension to their past together. One could interpret such a scene in any number of ways both innocent and otherwise, but Ai quickly apologizes and shuts the classroom door, believing she’d seen something she shouldn’t have. She’s also pondered ever since whether Sawaki was a factor Koito’s suicide. She wakes up in her cocoon bed, over 50% of which is being taken up by the smaller Rika.
Ai then awakes in Rika’s dream. Due to their proximity in bed they “synchonized”, as Ura-Aka tells them, and it’s Rika’s dream because she’s apparently the one with the stronger feelings. They crack their eggs at once, revealing two fans of the singer “Yu-Yu”. They were so fanatical, in fact, that when Yu-Yu committed suicide, they did the same. When Ai says “just like that?” Rika corrects her: their choice was neither easy nor casual. She knows, because she had a fan.
When the usual horde of Seeno Evils (which Rika calls “bystanders”) starts to swarm, Rika and Ai get to work smiting them with their weapons; Rika’s two swords resembling giant versions of the box cutter she used to cut herself. It’s determined the field of flowers is too wide open, so the four girls head to a lighthouse within the nearby woods. It’s there, while they have a couple minutes to catch their breath, that Ai asks Rika to tell her about Chiemi.
After hand-waving the scars Ai spots as “just a youthful whatever”, Rika starts out by explaining the formal and emotional context of a junior-idol handshake event. When you’re only mildly popular like her group was, the lines were shorter, which meant the same fans would line up over and over. Chiemi did this with Rika, who shook her sweaty hand many hundreds of times.
Eventually, Chiemi would give Rika money. Rika accepted it, and began to expect and even rely on it. Like the two Yu-Yu fans who had “sugar daddies”, Rika saw Chiemi as a rich patron. She later learned Chiemi was shoplifting and fencing stuff to make money to give her. When Chiemi started to think of them as friends, Rika ended their relationship, ripping Chiemi off like a Band-Aid and telling her she was too fat and ugly to be anything more than a fan and a wallet.
She never saw Chiemi again until her funeral, and was forever haunted by what she saw that day. In a gutting inversion of the geography of the handshake event, Rika and Chiemi have switched places. Peering into the open casket, Rika saw nothing but skin and bones, like a mummy. Knowing she’ll never be able to forget her if she tried, Rika took Chiemi’s hand one more time. Since then, she’s vowed to kill as many Seenos and Wonder Killers as it takes if it will bring her back.
The Seenos break through, leading to a frenetic chase up the spiraling lighthouse stairs. Ai stumbles, still processing Rika’s heartbreaking tale, but also acknowledging that while she receded into the Seenos at a crucial time due to fear, a part of her also resented Koito for never talking to her like friends should; the kind of talking she just experienced with Rika, which helped her understand better where she’s coming from and why she is the way she is.
She also looks on the Yu-Yu fangirls with a measure of envy. They were able to die with their idol. If Koito had asked her to die with her, she thinks she would have. But what’s done is done, and what was left unsaid remains so. Ai gets back on her feet and powers up her rainbow mace, striking a very cool heroine pose at the top of the steps and assuring Rika she’ll kill ’em all with her. Rika’s quizzical reaction is priceless.
From there, we meet the fangirls’ Wonder Killer, an older woman who stalked Yu-Yu and pushed her into suicide. Ai and Rika spring into action like the pair of valiant heroines they are. Rika frees the fans by slicing off the Killer’s arm, while Ai delivers a crushing blow to the face with her mace.
What follows is why it’s particularly hazardous to engage in boss fights before you’re aware of their special moves. The Killer unleashes a cloud of dark smoke that everyone is able to dodge except Rika, who is immediately paralyzed and soon turns to stone. Before her face petrifies, she wishes Ai good luck. It’s all up to Ai now: she must protect the petrified Rika and the helpless Yu-Yu fans while defeating the biggest toughest Wonder Killer yet.
Perhaps Ai and/or Rika haven’t considered that Aka and Ura-Aka are just using them. Or they’re fighting even while part of them is well aware they may end up getting cheated. But in either case they have no other choice. Now Ai’s mettle will be tested like never before. Hopefully she can get the job done and wake up beside Rika, with neither of them too seriously injured.
