Arc 5Dan Katō’s Pursuit
Araki uncovered Dan Katō’s plan to kill Nawaki and become Hokage, then killed him and concealed the body. He continued building his skills and standing in Konoha, but his experiments with poison were interrupted by a huge black bear.
- Araki returned home with blank tags from Kushina and made Explosive Tags in front of Kushina and Uchiha Mikoto, who had exchanged his earlier tags through the ninja tool shop.
- Araki sensed a pursuer during training and discovered that it was Dan Katō, who admitted he planned to kill Nawaki, murder Araki, and court Tsunade so he could become Hokage.
- Araki trapped Dan Katō with Wood Release and poison, but Dan Katō pursued him with the Spirit Transformation Technique and attacked him inside a mental space.
- The green chakra absorbed Dan Katō’s soul and restored Araki, who stabbed Dan Katō through the heart, learned the Spirit Transformation Technique, and destroyed the body.
- Araki hid Dan Katō’s remains, then told Uchiha Mikoto that he had overheard her investigation into Sora Hyuga and persuaded her that he had not killed him.
- Araki resolved to grow stronger within Konoha, studying medicine with Tsunade, making poisons and Explosive Tags, and learning sealing techniques from Kushina’s scrolls.
- Uchiha Nanagen'u questioned Araki while he trained in a grove, but let him leave after checking his scrolls and hearing his explanation.
- Araki prepared Purple Blood poison with crude equipment and went into the woods to test it, where a huge black bear confronted him.
