Poor, poor Nana. She’s been so traumatized by her parents’ murder and by the idea drilled into her hear that it was All Her Fault, she’s never been able to trust anyone long enough to become friends. It never occurred to her that anyone would want to be her friend unless something was in it for them, and in any case she never felt she deserved one.
But Inukai Michiru is different. She may be in the dark about Nana’s murders, but one thing she’s sure of is that Nana didn’t kill her parents. The reason for her odd behavior of late wasn’t because she suspected Nana, but because she was wracking her brain for a way to convince Nana her parents deaths weren’t her fault.
When Nana realizes this, she’s overcome by a feeling she’s never experienced before: pure, real friendship. The next day there’s an outdoor market from the supply ship, and Nana is compelled to buy Michiru a gift. Kyouya notices Nana is acting like she has a crush, and she absolutely does have an incurable girl-crush on sweet, kind Michiru.
Nana ends up giving Michiru a cute dog pen, while Michiru gives her a frilly pillow so she’ll sleep better. The two haven’t been closer, and at no point during the day does Inner Nana come out to reveal she’s still just messing around with Michiru to keep her guard down. No, she’s straight up fallen for Michiru!
Like Kyouya, Jin notices Nana’s lack of usual focus and sharpness, but considers it a repaid debt for rescuing his kitty friend to warn Nana about Michiru being lured out to a secret meeting. Sure enough, Nana is confronted and slashed across the face by the real murder both Nana and Kyouya have been looking for.
While running to Michiru’s rescue, Nana gets an almost too-perfectly-timed call from her mentor and handler, Tsuruoka, whose very voice seems to flip a switch in Nana’s head and return her to Unfeeling Cynical Killer Mode. She’ll let the students keep killing and weakening each other…including Michiru.
However, despite Tsuruoka’s call that seems designed to get her back on track, Nana still all but abandons her mission by sacrificing herself to save Michiru from the killer, who we learn is the Astral Projector, Tsurumigawa Rentarou. She rescues Michiru just as Michiru is saying Nana will come save her!
Still, Tsurumigawa can’t ignore his instinct about Nana hiding a dark and tortured soul beneath her cute and bubbly exterior. And while he’s right about that, the bottom line is that Nana isn’t going to let him kill Michiru. She says some heartbreakingly awful things to Michiru about them not being friends to get her to flee.
Then we learn what Nana said to Kyouya before racing to save Michiru. She tells him Tsurumigawa is the killer, and tells him to look for his real body and stop him while she saves Michiru. In a cute moment, Kyouya tries to protest Nana taking the dangerous job, but both sides of the job are dangerous in this case!
Kyouya finds Tsurumigawa in the bathroom and chokes him until his projection dissipates…but the damage is done: Nana has been “butchered”, and more to the point, doesn’t really mind dying here and now in this manner, considering the things she’s done. So of course Michiru returns to her side and starts working her healing magic.
While being healed, Nana is too weak to speak and protest that Michiru is using up what’s left of her life to save someone who doesn’t deserve salvation or mercy. She’s right back to hating and devaluing herself. It’s a state Tsuruoka cultivated in order to facilitate her development into a tiny pink murder machine, and Michiru almost broke her out of it.
Wait, what is this “almost”? The death of Michiru hits Nana hard. Perhaps her sacrifice wasn’t in vain if Nana changes her ways and stops blindly following Tsuruoka and the Committee, who, if we’re honest, sure look like they were the ones who orchestrated the death of her parents, then blamed it on her as part of her hitgirl conditioning.
Michiru wasn’t just Nana’s first friend, she was her only friend, someone who loved her unconditionally and would probably go on loving her even if she knew of the horrors Nana committed. Assuming there’s a second season of Talentless Nana, Michiru will be sorely missed, but maybe her loss will help Nana escape the box in which others placed her and forge her own path.
