Arc 5Wood Release and the Poison Front
After Kōki’s Wood Release devastated a Sunagakure force, the village targeted him while Konoha sent him to the front, where he served in the medical camp. Chiyo’s poison overwhelmed Konoha’s wounded, and Kōki developed an antidote that Rin Takakura tested successfully before they brought it to Genji Ryōma.
- Kōki used Wood Release to destroy much of the Sunagakure force, but an injured survivor escaped with intelligence about him, prompting Sunagakure to plan a hunt for the Wood Release user.
- Chiyo ordered Sunagakure to intensify the war, sought help from other villages, and planned to use Bunpuku to draw Kōki out, while Hiruzen Sarutobi sent Kōki and his restored jonin teammates to the front.
- Orochimaru assigned Kōki to the medical unit, where Rin Takakura and Genji Ryōma saw him treat wounded ninja and develop his medical skills.
- Rasa led a nighttime poison attack against Konoha, but Orochimaru’s forces drove Sunagakure back after their clash, leaving heavy losses on both sides.
- Chiyo’s poison then afflicted Konoha’s patients, and Orochimaru struggled to identify it or save the growing number of casualties as Tsunade remained missing.
- Konoha disrupted Sunagakure’s supply routes, temporarily halting the fighting, while Kōki studied Sunagakure’s poison records and developed an antidote.
- Rin Takakura tested Kōki’s antidote on herself after deliberately poisoning a cut, confirmed that it neutralized the toxin, and took him to tell Genji Ryōma.
