Perfect Preparation Arc

The Perfect Preparation Arc (をむ) is the tenth arc in Gege Akutami's Jujutsu Kaisen. It follows the Tokyo Jujutsu High students and their allies as they continue to deal with the fallout from the Shibuya Incident on top of preparing for Kenjaku's next great act of jujutsu terrorism: the Culling Game.

Contacting Master Tengen
Megumi convinces Yuji to help him combat the Culling Game and rescue his sister Tsumiki.

With Yuta and Choso, Megumi and Yuji return to Jujutsu High to form an unlikely team and contact Master Tengen. They sneak into Tokyo Jujutsu High and team up with Maki and Yuki Tsukumo. With Satoru Gojo sealed and Geto's motives unknown, Yuki believes this is their only chance to contact Tengen in order to get answers.

With Choso's guidance through Tengen's concealing barrier, the group reaches the Tombs of the Star. The main shrine appears to reject them at first, but before everyone leaves, Tengen decides to show themself.

Tengen offers answers to the questions they seek, but only in exchange for two bodyguards. Now that Tengen has evolved, they've become a target for Cursed Spirit Manipulation. The man possessing Geto's body is revealed to be named Kenjaku and he plans to force the evolution of humanity by merging them with Master Tengen. The Culling Game is a ritual to begin the complex merging process

Yuki and Choso willingly volunteer to be Tengen's bodyguards. In exchange, Tengen reveals there is a "back gate" to Prison Realm in his possession. However, the only way they can open it and free Satoru Gojo is using the cursed technique of a Culling Game player named the Angel, Hana Kurusu. The Angel has the power to extinguish cursed techniques and is located in one of the Tokyo colonies, one of ten colonies created by barriers around Japan.

The group discusses the rules of the Culling Game and formulates a plan while taking on their roles. Maki is to return to the Zenin clan and collect cursed tools to fight with. Yuta will enter a colony right away to take part in the Culling Game and gather information. Yuji and Megumi must go recruit Kinji Hakari the suspended third-year student for his strength.

Masamichi Yaga's Curse
In accordance with the notice released by jujutsu headquarters, Masamichi Yaga is to be executed for his role in inciting the Shibuya Incident.

This is obviously just a scheme by the higher-ups to pressure Yaga into revealing how to create fully independent cursed corpses. They had done so in the past shortly after Panda was born, arresting him under the pretense that Yaga could develop an army if he knowingly developed a cursed corpse with self-sufficient cursed energy. This is why Yaga has always kept the creation process a secret.

At one point he made an independent cursed corpse for Atsuya Kusakabe's sister to help deal with the loss of her son. Using Takeru's soul information, Yaga was able to develop a cursed corpse with his personality but it could not live with her because it had to remain a secret. Regardless, it helped Kusakabe's sister feel again, and Kusakabe has always been grateful to Yaga for that. Panda was arrested by the higher-ups in an attempt to draw out Yaga but Kusakabe frees him as a show of gratitude for Yaga.

After saying goodbye to Takeru and the other small independent cursed corpses, Yaga returns to Tokyo to meet up with Panda. However, he's intercepted by a sorcerer who demands he reveal how to develop independent cursed corpses or die on the spot. He's accompanied by Principal Gakuganji, who gets into a fight with Yaga and critically injures him.

Once the other sorcerer is dismissed, Yaga reveals to Gakuganji exactly how to develop an independent cursed corpse. Confused, Gakuganji asks why to explain it now and not before. With his last words, Yaga replies that this knowledge is "a curse from me to you". Panda finds Yaga shortly after he dies, but he does not attack Gakuganji. Instead, he mourns and sheds tears for his father.
