The following contains spoilers for Jujutsu Kaisen Chapter 205 ,"Stars and Oil”, by Gege Akutami, John Werry and Snir Aharon, available in English from Viz Media.

Chapter 205 continues Jujutsu Kaisen's trend of giving its most powerful characters absurdly complicated abilities. While facing Kenjaku in the series' first all-out smackdown between special-grade sorcerers, Yuki Tsukumo revealed her physics-breaking cursed technique.

Against any other jujutsu sorcerer, the reveal of Yuki’s inherited technique would have been enough to force them into an early surrender -- but the mighty Kenjaku approached the fight more like a bothersome challenge.

What Is Yuki Tsukumo’s Cursed Technique?

Before engaging Kenjaku in battle, Yuki watched the ancient villain engage a fully realized Death Painting in battle to ascertain his arsenal of techniques. Though he was outmatched, Choso put up a valiant fight against his creator Kenjaku. His final Piercing Blood attack contained no blind spots, forcing Kenjaku to use a mysterious hidden technique to avoid injury. Yuki jumped into the battle immediately after, implying that Kenjaku’s surprise reveal had been exactly what she was waiting to see.

Upon realizing his opponent had changed, Kenjaku adopted a more strategic attitude toward the fight. Since Yuki’s cursed technique was still a mystery, he planned to keep her at a distance and deployed one of the special grade cursed spirits in his possession against her. The curse was supposed to be one that removed obstacles out of the way -- and specifically targeted its victim's cursed technique -- so it was doubly surprising when Yuki kicked her shikigami in an attack that ripped a hole straight through it.

Yuki’s cursed technique is simply Mass. Without changing her actual weight or any of her characteristics, Yuki can apply an untold amount of virtual mass to herself. When combined with her martial arts skills, the result is lightning-fast strikes that deliver impossibly powerful blows, making Yuki one of the most powerful brawlers in Jujutsu Kaisen. Additionally, Yuki's perpetual escort -- the dragonfly shikigami named Garuda -- was transformed by her technique into a sentient cursed tool.

Yuki calls the virtual mass she grants herself “Star Rage”, and is also able to transfer its effects to Garuda. After destroying Kenjaku’s special grade spirit with her cursed tool, Yuki jumped right into the villain's face with a punch that sent him flying until he hit the barrier of Tengen’s space. Her punch was so strong that both of Kenjaku’s arms were broken because he tried to parry her.

After learning about Yuki’s cursed technique, Kenjaku began approaching their battle with a renewed sense of urgency. Restoring his hands was child's play with his reverse cursed technique, and he began to question Yuki’s hesitance to trap him in a Domain Expansion. Immediately after, Kenjaku revealed his Domain Expansion: Womb Profusion, not realizing that was exactly what Yuki and Tengen were waiting for.

Even so, the pair were struck by the villain's boldness and seemed conflicted about whether they’d be able to mount a counterattack in time. Yuki and Kenjaku’s face-off is already living up to Jujutsu Kaisen readers' high expectations, and the surprise reveal of a domain so early can only mean the fight is about to get even more exciting.
