Now that we know that Tomioka Keiko has the ability to send Kyouya back and forth through time, the question becomes, does Kyouya want to go back to the past or remain where he is? As Keiko says, there are few people who can claim they’re as happy and successful as he is. But Kyouya concludes that he didn’t want to go back in time to make a happier future; he wanted to experience pain and struggle alongside the talented creative people he idolized.
So even if, say, Aki decided she wanted to start drawing again, the fact remains that she, Tsurayuki, Nanako and Eiko all had their futures changed by Kyouya’s over-meddling, and that will never sit right with him, so it’s back to the past with him. It seems Keiko, whoever or whatever she is, brought Kyouya to this alternate future to teach Kyouya a lesson, in addition to giving him the choice to go or stay.
After a heartfelt sequence of final scenes with Aki and Maki, Kyouya is ready to go back. Keiko sends him back to the same time he left, when Tsurayuki dropped out. Aki and Nanako aren’t sure what to do about it, but Kyouya adivses that they all stay the course. If there’s a way to bring Tsurayuki back into the creative world, he’ll find one, but this time he’s not going to be so forceful and so certain.
Just as the members of the Platinum Generation put their trust in him, this time Kyouya is going to trust in their ability to shine and fluorish without undue interference or compromise. When Nanako is given an offer to work for another doujin group, she sheepishly asks him if he’ll proverbially hold her hand. Having seen what becoming overly dependent on him did to Nanako’s future, he insists she try being independent on this project. Even if he comes off as rude or mean, it’s in Nanako’s best interest.
He’ll still support her, but he won’t let her rely on him entirely again. Aki proves trickier, as she hits the very same rut that would define her future self as she transitioned from a creative life to a domestic one. Kyouya realizes that asking her to work so hard and compromise her artistic vision for the game took a toll, and that coming out of the rut won’t be a fast or easy process, but it will and does eventually happen, and without undue meddling from him.
Kyouya ends up literally bumping into the girl who will one day become Minori Ayaka, sporting her natural black hair color. Akaya seems embarrassed when Kyouya sees she has the game he made along with some promising sketches, but there’s no disputing she’s dedicated to being the best goshdarn illustrator she can be, inspired as she is by Shinoaki’s work. This must feel gratifying to Kyouya, as by abandoning that possible future he also feared he undid the good he did for Ayaka’s future.
But then, that’s just his ego talking; the same ego that thought he was singularly, personally responsible for upheaving everyone’s lives, when in reality it was a whole host of variables. It’s the same with Ayaka; she’s going to be alright, especially if the artist she adores continues to draw, as Aki does.
As for Eiko, Kyouya now realizes that she considers herself more than just a friend, creative colleague, and confidant. The future Eiko loved (past-tense) Kyouya, that means this past Eiko is in the process of falling for him, if she hasn’t already. Her blush as she admits she’d drop everything to help him if he was ever in trouble says a lot.
But Kyouya isn’t interested in dating Eiko, at least not at the moment. His primary goal is to undo the damage he did to Tsurayuki’s creative motivation. His confronting Tsurayuki as he exits a theator marks the beginning of his Remake Version 2.0, and even hints at a possible second season (though there hasn’t been any announcement of one, so who knows).
If this is the end, it’s a moderately satisfying one, as it has Kyouya on a sustainable path where he’s aware of his “power” and no longer breathlessly achieving happiness at the cost of others’ success. Even as he’s reverted to a younger version of himself, he’s grown as a person and a friend to these talented people. And so the struggle continues.
