Jujutsu Kaisen Chapter 192, Sakurajima Colony, Part 2, is mostly the beginning battle between Maki, Noritoshi Kamo, and Naoya Zenin. Prior to that we get is a brief confirmation of what causes the creation of a vengeful curse spirit. Yoshinobu Gakuganji reminds Noritoshi that a sorcerer must use jujutsu to prevent another sorcerer from becoming a curse spirit. I mentioned this in my last chapter review but what’s interesting is that apparently Maki who has no curse energy potentially could create vengeful spirits. It’s not made clear if she could do this, as Naoya Zenin makes a point of saying that Maki’s mother killed him.
It’s possible that Maki being a bit of an anomaly wouldn’t function as a normal human and/or a jujutsu sorcerer. Toji Fushiguro hasn’t been credited with creating any vengeful spirits so I’m doubtful. Anyway, Naoya states the obvious that he’s going to kill Maki. While he has her pinned down, Noritoshi Kamo shoots an arrow distracting Naoya. Maki escapes, while Naoya notes how much he “hates” Kamo’s cursed technique. Noritoshi can’t sense Maki with his eyes closed. He can of course tell where Cursed Naoya is. Still Naoya is too fast for Noritoshi to hit with his arrows.
Despite this Maki is able to grab Naoya and toss him to the ground. Noritoshi manages to hit Naoya with three arrows then Maki cuts him with her sword. Naoya notices that he can feel pain as a curse. I’m not sure if it was ever explicitly mention that curse spirits experience pain but I just assumed they did. Naoya feints regret for killing so many curse spirits now that he knows they have pain. When it looks like Naoya might go down easy he begins to transform. Turns out he was a curse womb. Like Dagon he was a sentient curse womb. Once they shed the old skin they become more powerful beings. Noritoshi uses Piercing Blood to try to stop his transformation, but fails. Naoya emerges in a skeleton form. He quickly attacks Noritoshi, sending him flying.
