Yuuji is in the fight of his life, but he’s also in the middle of a lecture. Nanami may not be a teacher, but he’s still going to coach up the young buck so he doesn’t get himself killed. Yuuji, for his part, pays attention. He’s not the kind of hero who’s going to defy his sensei because he thinks he knows better or thinks he’s strong enough.
Nanami’s plan with Mahito is simple: wait for an opening, then rain blows upon him with Yuuji. It takes a little under four minutes, but the two jujutsu sorcerers eventually get the timing right, and then it’s open season. That’s when Mahito plays dirty, unleashing a trio of deformed humans on Yuuji, knowing he doesn’t have the heart to kill them.
Only, to Mahito’ surprise, he does. It happens offscreen, but Yuuji deals with the humans before they kill him. That’s when Mahito decides to push all his chips into the pot with Domain Expansion, engulfing only Nanami while Yuuji is trapped outside. Nanami, all but certain this is the end for him, looks back on how he got back into sorcery in the first place.
We watch him live his life in a pinstripe suit stealing money from wealthy people in order to make other people wealthier. It’s a job he’s good at but gives him no joy, and he believes no one would miss him if he simply ceased to exist. Then, when a cute young woman at the bakery has a low-level curse on her shoulder, he exorcises it, she thanks him profusely, and he decides right then and there to give Gojou a call.
Of course, while more rewarding and a better use of his time and talents, jujutsu sorcery was always going to be a higher-risk proposition. Mahito thanks Nanami for getting him to unleash his domain, but Mahito isn’t interested in the gratitude of a curse. He’s gotten enough thanks from people like the bakery lady that he has no regrets.
Only before Mahito can do Nanami in, Yuuji successfully busts through the domain from the outside, which is far easier than trying to break out. Because Yuuji is the vessel for Sukuna’s soul and Yuuji is now within Mahito’s domain, Mahito touches Sukuna’s soul a second time, and Sukuna punishes him—a flick of his hand puts a gaping gash across Mahito’s chest.
With his cursed energy depleted from summoning the domain, Mahito puts everything he’s got left into making himself as big and fat as possible. Yuuji proceeds to put everything he has into a Divergent Fist, which pops Mahito like a balloon, but crucially does not kill him. He’s able to slip back into the sewers. Nanami has his colleague Ito try to track him down, while Yuuji passes out from exertion and his many wounds.
When Yuuji wakes up he’s back at the school, specifically the morgue, where he reflects on the human life he was forced to take, and how it led to the realization that while he’s been trying to ensure everyone gets a “proper death”, he has no idea what that is. Nanami has news for him: no one does. All he knows is there will be many more people like him who will need him, so he’d better not die improperly himself.
Back at the late Yoshino Junpei’s high school, the lead bully Itou is called out by his peers filling out surveys, and the ineffectual teacher who looked the other way for so long develops a spine. He knows both he and Itou bear the crime of killing Yoshino’s heart, and will have to keep bearing it the rest of their lives. While Junpei died far too early, his death wasn’t without purpose.
Meanwhile, Yuuji is back on his feet and above ground at Jujutsu High, meeting Nanami and Gojou in the hall as a full-fledged jujutsu sorcerer. While Mahito & Co. will surely go after him in hopes of releasing Sukuna (who Mahito believes can singlehandedly usher in the “Age of Curses”), his more immediate concerns are reuniting with Megumi and Nobara (at last!) and participation in the Kyoto Sister School Exchange Event.
As for this episode, I consider it the best of Jujutsu Kaisen yet, an absolute tour-de-force of combat animation and sakuga, staging, pacing, atmosphere, peril, and sweet, sweet near-victory. Nanami’s backstory was well-timed, efficient, and effective at giving the guy some dimension, while Mahito remained an entertaining adversary to the bitter near-end.
