Fresh off the amicable resolution of the Koga Tomoe arc, we are presented with not one but two new mysteries, both involving characters we’ve dealt with before. Just as Sakuta’s earlier, seemingly random encounter with Koga paid off nicely (butt-kicking leading to quantum entanglement), his past established crush on “Makinohara Shouko” makes the sudden appearance of someone with the same name who looks just like her, only two years or so younger, that much more intriguing.
At the same time, Futaba Rio is elevated from Sakuta’s sounding board and scientific consultant to an actual participant in Adolescence Syndrome weirdness. Sporting a fresh look with ponytail and contacts, Futaba doesn’t have any answers for Sakuta about why some younger copy of his crush suddenly appeared. If it’s not causing any harm, just don’t worry about it for now.
And the episode doesn’t; not really. Shouko is mostly tabled as the episode veers toward the slow-burn relationship of Sakuta and Mai, who is done with a job early and surprises him by showing up at the restaurant where he works, and even implies he’ll let him make out with her later.
After his shift, the two spot Futaba entering a Net Cafe and follow her. Using Mai’s phone, Sakuta calls her (presumably so the sound of her phone will indicate where in the cafe she is) but as he’s talking to Futaba on the phone, he and Mai spot a second Futaba. Yup, she’s got herself a doppelganger!
This Futaba, with glasses and no pony tail, finds herself temporarily homeless, since the other Futaba is already living in her house. Sakuta invites her to stay at his place, something Mai only approves if she can spend the night there as well.
This Futaba is extremely coy about what could have brought on Adolescence Syndrome to the point she’d split in two. Sakuta puts her up in his room with Mai, but Mai soon comes out to the living room where he’s sleeping, giving him the hints and nudges he needs to indicate she’s open to him making a move whenever, not just a special occasion for an apology. After all, he’s her boyfriend. Unfortunately, their kiss attempt fails when they bump heads. These guys are just to frikkin’ cute together.
The next day, after some domestic bliss with his full house, Sakuta has Mai watch one Futaba while he goes to school to track down the other. Shouko shows up, but nothing further on her situation is explored; it’s just an opportunity to confirm to Futaba that there is a new Makinohara Shouko in Sakuta’s life.
At school, while on the way to science club (which consists only of her) Futaba stops to watch Kunimi play basketball, which is where Sakuta finds her. After talking with her for a bit, it’s obvious he’s not dealing with “real and fake” Futabas; they are both Futaba, through and through.
That’s not to say the two aren’t very different; not just in appearance (though that’s a start): the ponytailed, contact-wearing Futaba just seems far more assertive, confident, and active, whereas the Futaba back at his place seems, well, almost the opposite of those qualities.
When Kunimi’s girlfriend confronts Sakuta with a social media feed of Futaba taking risque pictures of herself, my theory solidified: the two Futabas embody her id and ego (or super-ego). She is out of balance, and her unrequited feelings for Kunimi seem to be the cause. The question is, how is Sakuta going to help her restore that balance and become one again…and where does Shouko fit into all this?
P.S. A powerful little moment is when Mai’s cell phone goes off and Kaede suddenly looks like she’s about to be shot. Now we know why Sakuta doesn’t own one!
P.P.S. Futaba fell for Kunimi when he bought her a Choco-Cornet; Id-Futaba makes that her social media handle for her photo feed.
