WEP made no secret of there being four main girls, so with its fourth episode it introduces the fourth girl: Sawaki Momoe. Still, Miwa, the egg girl she’s helping, calls her “Momotarou” because she’s so tall and manly. Miwa was driven to suicide by her dad’s boss who molested her, then fired her dad when she accused him.
Meanwhile, Ai is running, loath to fight the Wonder Killer alone, but it turns out she doesn’t have to: Yu-Yu’s fans lend her penlights, which turn into new weapons with which she slashes the Killer’s many tentacles. It’s a case where the Egg Girls won’t just stand passively by and wait to be rescued, but actively aiding their heroine.
Miwa looks poised to stand passively, but when Momoe starts having some trouble, she uses herself as bait to give her heroine an opening. She also taks the opportunity to tell the pervert to touch his wife whom he loves—not her. Back with AI, the Yu-Yu fangirls help their own case further when they stop the Wonder Killer in her tracks with a video of their shared idol.
They buy enough time for Ai to hang in there until Rika returns—as has been established, they’re immortal, so her petrification eventually wore off—and de-tentacles the Killer, allowing Ai to deliver the coup-de-grace, completing the rescue of the fangirls, who also declare themselves fans of the two-girl unit that is Ai and Rika before vanishing.
Momoe also says goodbye to Miwa, who insists on being held in the arms of the person she fell in love with in their short time together. Momoe is left alone on the train platform, no doubt wishing at some point one of the egg girls she rescues won’t see her as a man and fall in love with her.
At the hospital, Neiru makes a fast recovery to the shock of her healthcare providers, demonstrating she’s ready to be discharged by performing a brief but perfect floor exercise in the rehab room. As Ai confirms with her firmer abs, their exertions in eggland don’t just bring real injuries into the real world, but also increases their muscle tone, stamina, and general physical toughness.
Ai learns that Neiru doesn’t go to school either, but for a very different reason. After riding in her sumptuous Mercedes Maybach Pullman and heading up to the top floor of a snazzy office building, Ai learns that Neiru’s dad doesn’t work there, she works there…as president.
Momoe is urged by the two sackheads to make friends and look for the sunflower—a clear reference to Ai’s shirt. But as Ai and Neiru amiably chat, they walk right past Momoe without noticing her.
When Momoe tells her next Wonder Killer target that she’s actually a girl, the egg girl who falls in love with her doesn’t care; she loves her anyway, and leans in for a kiss before vanishing just like the others. Momoe visits the statue of Haruka, the girl she’s trying to save, who—you guessed it—also loved her.
Momoe returns to the egg gachapon, where Neiru and Rika are waiting for Ai. Rika immediately misgenders Momoe as a handsome, strapping young lad, but protests to the sackheads that boys shouldn’t be allowed. The sackheads tell Rika not to get hung up on gender, since they made this place for anyone who wants to bring children who succumbed to the “temptation of death”—i.e. suicide—back to life.
As the sackheads presumed, it would take a sunflower for Momoe to make friends among her fellow egg girl heroines. She stares into her reflection, desperate to be seen for what she is rather than have others project what they want her to be, and weeps. Ai approaches and asks if she’s okay, and Momoe asks her “What do I look like right now?” Ai gives precisely the answer Momoe needs: “Like a crying girl…who looks like a model.”
Ai, whose mom once ran a fashion magazine, has seen female models of all shapes and sizes. She’s seen femininity in all its forms, not just the “classical” or “conventional” ones (though I admit those are both super-loaded adjectives). She goes on to compliment the contours of Momoe’s neck, as Momoe recognizes Ai is the sunflower she sought.
With the ice broken, Neiru and Rika join the conversation about necks and Adam’s apples, with Rika half-jokingly asking for an assessment of her neck, which is likened to a “puppy’s”, leading all four to eventually join in the laughter. We’ve seen what Ai and Rika were able to do working together. I imagine that the four of them fighting as one would be more effective still!
