I approached the Steins;Gate movie with an unusual amount of glee and anticipation, and doggone it, the movie was just as good as the TV show. Far from superfluous as one can get, it actually ended up tying up a few loose ends from the show, serving as a second season of sorts, compressed into 90 minutes (or four TV episodes’ worth).
A year has passed since Rintarou achieved the Steins Gate World Line (SGWL), and Kurisu finally returns to Tokyo, ostensibly for lectures, but actually to visit the lab, and Rintarou in particular.
While there’s initial tension and combat between the two as neither seem all that comfortable being overt about their feelings for one another around the others, but after Kurisu drinks a beer or two her facade comes down and she just wants Rintarou to hold her. (Also, Rintarou gives her “my fork and my spoon” as a gift)
Everything is happy and lovely, were it not for the proverbial chickens coming to roost in the form of side-effects from all of Rintarou’s time travel starting to become a bigger and bigger problem. Things in the SGWL are causing flashbacks that are giving him a vertigo and threaten to break his mind’s grip on which world line is the real one.
As this is going on, a shadowy figure, who is, of course, Suzu, follows Kurisu to her hotel room and gives her three words that make no sense to this Kurisu, but will mean everything soon enough. You have to leave it to Suzu; she always seems to pop by from the future to steer people in the right direction.
Leave it to a cruel and torturous universe to give Rintarou everything he ever asked for in a world line: no WWIII down the road; both Mayushii and Kurisu alive and well, only to make it so he can’t live in that world. I assumed his flashes of other lines would get worse and worse, but I was frankly shocked to see him literally vanish into thin air just as he was putting on the lab coat Kurisu repaired.
Yet even when Kurisu and the others realize Rintarou is missing from their world line, and build the time leap machine to go back to the rooftop barbecue, he’s still fluctuating, and Suzu explains that it’s because the SGWL is very close to another line, one only a tiny fraction of a percent different from it. The only difference between it is that Okabe can only exist in one.
Kurisu wants to fix things, but Rintarou doesn’t. As he said, he has the world the way he wants it. If he can’t live in it, so be it. Better for there to be peace and for the girls he loves to be alive than to risk altering the world line and causing more damage just to save him.
Despite the fact Kurisu really doesn’t Rintarou to vanish or to forget about him, that’s exactly what Rintarou asks of her, in a heartbreaking scene at the train station before dawn.
But he might just be sabotaging his own cause by kissing her, because forgetting Rintarou proves extremely difficult due to all the titular deja vu, which was earlier identified as a form of Reading Steiner. Kurisu tries to get on with her life, but every time she thinks she’s forgotten him, some detail in her life reminds her of him anew. She even changes her mind and runs to the lab as fast as she can, but before she can say anything to Rintarou, he vanishes again.
Suzu’s still there, not just with wisdom form the future but from Kurisu’s future self, who inevitably invents the time machine. The same stubbornness that has made Kurisu so endearing for so long is also the stubbornness of sticking to her promise to Rintarou not to alter the world lines for his sake.
Suzu tells Kurisu that if she’s able to imprint a powerful memory in Rintarou within the SGWL, his mind will be able to keep him in that world line, so he won’t vanish in 2011. In other words, if Kurisu is honest with herself and doesn’t give up on him, she can save him.
Kurisu takes Suzu up on her offer to take her back in time (in the time machine she herself built in the future) and chooses a particular day in 2005 she knows to be significant in Rintarou’s life. But when she tries to get his attention, she slips and falls in the road, and as he runs out and gets hit by a truck.
This setback spooks Kurisu, who literally shudders to think not only how much worse Rintarou’s fate could become if she keeps meddling, but also just how much death and suffering Rintarou went through for her and Mayuri’s sake. She’s just not sure she can go through all that.
But then, every other interaction with every other lab member seals it: nobody who knew Rintarou will ever entirely forget him, even as the world and their lives go on without him, Kurisu doesn’t want to live in that kind of world. All the lab members end up seperately recalling snippets about Okarin and Hououin Kyouma, culminating in Kurisu donning a lab coat and roleplaying as Kyouma himself in a masterfully adorable performance.
Reassured that bringing Rintarou back is the right thing to do, she returns to 2005, remembering what he said when they first kissed when he had to say goodbye to her: that it wasn’t his first. Kurisu remedies that by meeting with the younger Rintarou, who is on his way to see Mayuri at the graveyard (which is when he declares her his hostage). Kurisu tells him the story of the Mad Scientist Hououin Kyouma, and then steals his first kiss. It’s another momentous scene firmly grounded in the continuity of the show that for lack of a better term causes all the feels.
It also does the trick, as Kurisu is able to reunite with Rintarou, who was sitting alone in an empty Akiba. Empty as in it looks like no one in the SGWL ever existed where he is, just as he never existed there until Kurisu fixed things. This results in another happy ending, which we always seem to get in Steins;Gate, which would seem indulgent if those endings—including this one—weren’t so gosh-darn earned. They’re not created by conceits, but by logical conclusions to the story; Kurisu figuring out what she needs to do, pushing past the difficulties, and doing it.
And if Kurisu’s final smirk doesn’t melt your heart like artisanal butter in a skillet, you might not have any. Heart…not butter.
This movie did the improbable by intensifying my already unreasonable fanaticism with Steins;Gate. S;G has it all: baller writing; hard-hitting drama, laugh-out-loud comedy, breathtaking twists, not-totally-ridiculous science, world-class voice-acting, unique design, ethereal soundtrack and immersive atmosphere. The movie makes me that much more excited about a future sequel in the works. Whatever risk that move entails, no show is worthier of the benefit of the doubt than this one.
