Igarahi Chika seems like a last-minute addition to the cast in order to create one last conflict that will test Hikari and Iroha’s bond of love and trust, but he’s a lot less of a douche than I thought he’d be. When he learns that Hikari’s glasses were a gift from his late grandmother, he promptly has them replaced. Takanashi still hasn’t publicly atoned for the shit he did to Hikari, and he’s somehow in the clear, but here’s Chika, doing the right thing without delay.
Sure, he deems Hikari too mediocre to date his sister and suggests he break up if their relationship isn’t “worth” anything, that’s typical Unbidden Brother Protection, and he doesn’t make it an order; he puts the ball in Hikari’s court by making him ask himself: what can he do for Iroha, besides the “nothing” of which he only believes himself capable?
After an advice session with Ishino that costs him the price of two big parfaits, Hikari settles on a token of his commitment to and bond with Iroha: a ring. Ishino raises the difficulty level by saying he can’t simply trade in his otaku junk for the scratch to buy one; he should work for it, and arranges a part-time job as an amusement park mascot (sadly, not at Amaburi).
However, while Hikari only has the best intentions in terms of wanting to see her smile, like she did when he made her a figurine of herself, he demonstrates that he still has a lot to learn by basically cutting Iroha entirely off without explaining why.
The desire not to spoil the surprise actually ends up hurting Iroha, especially, when she doesn’t have any answers for Chika, who decides to back her against a wall while reminding her they’re not actually related by blood…which considering how the episode ends, seems like a bit of a non sequitur. Ultimately, he lets Iroha be, hoping it all works out and she isn’t hurt by Hikari.
Professions of absolute trust notwithstanding, Iroha knows what she has to do to put her mind truly at ease: ask Hikari directly what’s going on. She gains her courage from Itou of all people, who she checks in on after he’s hit in the face with a soccer ball.
Itou was distracted and fatigued by his continued struggles trying to get Ayado to notice him like a girl notices a boy, rather than simply a messenger who relays invitations to her on behalf of his circle of friends.
I still don’t think Ayado would consider Itou completely out of the question as a partner, but Itou decides to end his part in the show still on the fence, unable to do what he inspires Iroha to do: tell the person he loves how he truly feels.
It’s not an exaggeration to say a great deal of luck is involved in lasting relationships. Like, say, the luck of having purchased a ring to gift to your girlfriend the very day she finally confronts you about what you’ve been doing after school. It’s not the best ring, but after he was able to measure her finger while she slept at his desk (which I guess isn’t creepy if you’re dating…) he couldn’t hold himself back from buying one.
He slips it on Iroha, whose tears of frustration turn to joy, they share a kiss right there in the school hallway. After the credits we see Hikari, Iroha, Itou, Ishino and Takanashi (but notably not Ayado) at Takanashi’s latest ramen find. And that about does it?
Wait: What about all that foreshadowing about Hikari and Iroha’s relationship being a ticking clock due to her having to move? It’s not addressed. Itou’s Ayado odyssey ends on an ellipsis. Takanashi still shoots down any tortured attempt from Ishino to get him to go out with her.
So, if I had the time machine from Steins;Gate (or anywhere, really) and had the chance to decide whether to watch 3D Kanojo again? Well, probably. Despite its horrrrrrible animation and many untied loose ends, I still felt like it had some interesting things to say about first love, particularly from the perspective of two “less-than-ordinary” personalities.
