In the finale, we spend virtually the entire time inside Nezumi’s head as he ponders which of the one hundred wishes he has will be the one he asks Duodecuple to grant as a reward for his winning the Juuni Taisen.
For all that inner monologue, we don’t learn anything about Nezumi’s past, only his very mundane present, in which he attends high school and stands out mostly due to how antisocial he is.
We see his ability in action on more than one occasion as he weighs his options, and early on these are mostly frivolous, such as wishing for everyone in his class to die, or for the skirt of only girl who talks to him to flip up in front of him.
But the more he wracks his brain trying to think of a proper wish, the more rationales he comes up with to render those wishes undesirable—living forever; remaining young forever; making everyone happy; gaining the ability to survey a thousand possibilities instead of a hundred—they all have their cons that leads to their dismissal.
He considers the wishes of the other, now-slain warriors, which is interesting because throughout his ninety-nine failed attempts to win, he manages to interact peacefully with each and every one of his eleven adversaries. In a way, that’s rather apropos, since at one point or another everyone has to deal with rats.
In one of those deleted possibilities, Tora tells him how her wish is to fight beside (or possibly against) Ushii; it’s a wish that’s actually granted in the timeline Nezumi ultimately goes with. Tora turned out to be my favorite of the twelve warriors, so it’s gratifying to hear that despite losing the competition, her wish was fulfilled and she died without regrets.
If there’s one thing this final episode makes clear, it’s that Nezumi’s ability is a curse, since he remembers everything that could have happened but didn’t. So the wish he ultimately comes up with—to be able to forget everything that’s happened, or might’ve happened—seems like the best way to go. After all, his memories of all those countless deleted possibilities hampered his ability to choose any other wish.
By the time he’s counted up to 99, he’s an exhausted fellow seemingly on the verge of mental breakdown. Being allowed to forget it all is a tremendous relief even his classmates notice when he’s happily dozing at his desk.
With a RABUJOI Score well under 7.5 and a MAL Score of barely 7, Juuni Taisen was never in danger of winning any “Anime of the Year” awards. Of the shows we haven’t dropped this Fall, it’s the lowest-rated.
The reason I stuck with JT was its efficient and reliable structure: twelve episodes, twelve characters, eleven all-but guaranteed deaths, and one winner. Many of those characters and their backstories were serviceable, particularly those of Niwatori, Sharyu, and Tora. The CGI-assisted combat was also a strong suit (though IMO there wasn’t enough of it).
I wish Ushii and Usagi had gotten proper backstories. The wish-granting ability of Duodecuple was way too broad. Nothing really came of the silly oligarch gambling angle. But Juuni Taisen was still a fun, if flawed, ride.
