Arc 12Madara and the Hidden Orphan
Akaseki helped defeat the Sky Ninja fortress and learned of a dangerous Sage Mode trial, then investigated the deaths of Konoha shinobi and encountered Madara Uchiha and Black Zetsu. The arc ended with Akaseki warning Tsunade about the threats as Nagato remained in Madara and Black Zetsu’s hands.
- Akaseki and his companions infiltrated the Sky Ninja fortress, defeated its defenders, and discovered that the Void Demon God was draining captive citizens to power it.
- Akaseki entered the seal and overcame Void, restoring the seal before the Sage of Six Paths appeared and enhanced his bloodline while directing him toward Ryūchi Cave’s Sage Mode trial.
- After the fortress fell, Akaseki urged Jiancheng to rescue the captives and discussed Konoha’s political and economic position before reporting to Jiraiya at the Land of Rain supply force.
- Akaseki investigated the deaths of two Konoha Chunin and two Rain civilians, recognized signs of Shinra Tensei, and searched for the missing red-haired child Nagato.
- Akaseki confronted Black Zetsu, who claimed to be Indra’s will and revealed that Madara Uchiha carried Indra’s reincarnated chakra.
- Madara and Black Zetsu attacked Akaseki, but he escaped after Madara recognized Setsuna’s Towa in his eyes, and Nagato fled, while Madara insisted the boy must suffer and grow stronger.
- Akaseki reported Madara and Black Zetsu’s abilities to Tsunade, warning that Black Zetsu’s hand-seal-free Wood Release, regeneration, and concealment made him especially dangerous.
