Well, what do you know, not only can Kuroko carry an episode, Ruiko can carry a pair, along with Frenda Seivelun. Most of the episode is one big shopping mall chase scene and showdown between Frenda and Yumiya Rakko, two sadistic hunters with poor Level 0 Ruiko in the middle. And yet the episode manages to infuse some humanity in both killers.
Having gone this far to save Ruiko, Frenda never quite feels right abandoning her to Yumiya, even when it seems the best shot at surviving. After all, Ruiko shared the last of her mackeral with her. As for Yumiya, she’s in full Assassin Mode until she spots some classmates from her school, and for a moment she’s reverted to her shy and lonely persona.
Yet just as Frenda gradually figures out Yumiya’s tactics as she survives one bullet wound after another, Yumiya draws on her experience with being an extreme loner to aid her assassin’s skills. When Frenda finally decides splitting up is necessary, she tries to find the right way to break it to Ruiko—who proceeds to suggest splitting up before her.
Frenda can’t help but be impressed with Ruiko’s attempt to be “a perfect soldier” despite knowing it could mean her death. Ruiko serves as a decoy with stuffed animal bombs that among everyone in the mall only one person reacts to as bombs: Yumiya. This allows Frenda to finally spot her, and when she launches herself at her with a devastating kick she doesn’t miss her face.
A thrilling two-sided beatdown ensues, with Frenda hitting the deck indicating to Yumiya that she’s won. However, Frenda is merely getting low because it’s the safest position to be in for when she detonates bombs all over the mall, sucking the oxygen out of the air and with it Yumiya’s ability to smell or breathe. It’s a very demolition expert-y way of getting the upper hand in a fight.
Yumiya tries to counter the thermobarics by rushing to the nearest broken window to take in air, but that’s just when Frenda pounces out of the smoke, stuffs mini-bombs in Yumiya’s gob, kicks her out of the building, and sets off the detonator with a particular sense of self-satisfaction followed by a huge bang. Throughout their battle, Ruiko managed to blend in with the bystanders and calmly escape the mall.
With the extent of the threats to her life still not fully known, Ruiko takes up temporary residence at an Antiskill facility, and is restless and anxious until she finally receives a message from Frenda, who asks her to have dinner ready when she stops by, a reply to Ruiko’s invitation before they split up.
As for Yumiya, she’s alive but down an eye and most of her face due to the blast, and her SCHOOL boss Kakine Teitoku isn’t in the mood to indulge her in seeking revenge. Getting ahold of the Tweezers takes precedence, and her role in the op is going to a backup.
Back home, Ruiko tries to reach back out to Frenda but doesn’t get any replies, yet still prepares dinner for two. When the doorbell rings, she’s so excited she stubs her toe on her desk (as beautifully animated as the earlier battle), and just as dejected when it turns out to be Uiharu.
The good news? Ruiko learns no one died in the mall explosions. The bad news? She’ll probably never see Frenda again. That hurts, and you can sense Ruiko’s pain. Frenda, so much more powerful an esper than her and heartless a killer to boot, and yet someone with whom Ruiko could share a can of mackerel. Ruiko may have acted like the perfect soldier that day in the mall, but at the same time, Frenda was the perfect friend.
