Arc 15Isshiki’s Desert Battle
Ōtsutsuki Isshiki infiltrated Rōran to reach Momoshiki Otsutsuki and Urashiki Otsutsuki, only to discover that Sōkyū Hatake had prepared for him. Their fight moved to a distant desert, where Hatake shattered Isshiki’s Root Source Gate and left him weakened.
- Ōtsutsuki Isshiki received Urashiki Otsutsuki’s message and traveled to Rōran to investigate Sōkyū Hatake’s research and seek a chance to rescue the captives.
- Ōtsutsuki Isshiki infiltrated Rōran’s underground laboratory and crossed its traps, then found Momoshiki Otsutsuki and Urashiki Otsutsuki restrained in containers.
- Orochimaru and Mayuri Kurotsuchi revealed that they had lured Ōtsutsuki Isshiki into a trap, but he broke through the laboratory defenses and freed the captives by destroying their containers.
- Ōtsutsuki Isshiki revealed that he had used the infiltration to draw Sōkyū Hatake out, and his chakra surge collapsed the laboratory around them.
- Sōkyū Hatake moved the battle to a remote desert, where he and Ōtsutsuki Isshiki exchanged attacks as Isshiki drew on the God Tree and transformed through Kāma’s Deep Resonance.
- Ōtsutsuki Isshiki opened the Root Source Gate to sever Sōkyū Hatake’s connection to the world’s physical laws, but Hatake shattered it with the Thunder God: Spear of the World.
- The Root Source Gate’s destruction weakened Ōtsutsuki Isshiki, and Sōkyū Hatake told him that this world’s laws would not allow outsiders to take root.
