Chapter Summaries

Hajime Kashimo defeated Ryu Ishigori in Sendai but spared him and promised to let him catch up. After Kashimo accepted Lu Yun as his coexisting partner, Lu Yun received rewards for Kashimo’s victories and gained a major increase in cursed energy and several new abilities.

• Hajime Kashimo defeated Ryu Ishigori and left him alive, telling him to grow stronger and challenge him again.

• Hajime Kashimo yielded control to Lu Yun, asked him to find Sukuna, and fell asleep.
• Lu Yun received rewards for defeating Dhruv Lakdawalla, Kurourushi, Takako Uro, and Ryu Ishigori, gaining new abilities and greatly increased cursed energy.

After Hajime Kashimo woke to Lu Yun’s sudden increase in cursed energy, Lu Yun convinced him that his power came from a cursed technique that grew stronger by defeating opponents. Once Kashimo went back to sleep, Lu Yun tested a new ability on the injured Ryu Ishigori and discovered something unexpected about the cursed energy he had sent into him.

The rewards from defeating the Sendai Four Heavenly Kings raised his strength to Special Grade level, though he knew he was still no match for Sukuna.

• Lu Yun realized that Cursed Energy Erosion made a charge grow after one hit by consuming his opponent’s cursed energy, greatly enhancing Hajime Kashimo’s Executioner’s Lightning.

• Lu Yun briefly imagined he could kill Sukuna with one punch, then recognized that Sukuna could still cut him apart.

Lu Yun arrived during Naoya Zenin’s confrontation with Yuji Itadori and Choso, mocked the Jujutsu Higher-Ups for burdening Yuji, and showed that he could touch Naoya despite Projection Sorcery. Naoya remained convinced Lu Yun was a weakling and attacked from his blind spot.

• Lu Yun crashed onto the road, hurt his back on his stun baton, and angered Naoya Zenin, who insulted him and called him a monkey.
• Naoya told Yuji Itadori that the Jujutsu Higher-Ups had ordered his execution and planned to use him to lure Megumi out.

• Yuta Okkotsu fully manifested Rika and used copied Cursed Speech to halt Lu Yun's charge, causing the lightning projectile to explode before it could be fired.

Yuta Okkotsu used Rika and Domain Amplification to cut through Lu Yun’s elemental transformation, but Lu Yun avoided further contact by turning into lightning and flying into the sky. He left Okkotsu below, unable to reach him.
