Arc 4Blood Moon at War
Muzan established Blood Moon, recruited allies, and used his abilities to reshape the war against Sunagakure and Kumogakure. As Iwagakure invaded, he led a squad toward Kannabi Bridge and stayed behind to face the Stone Ninja.
- Muzan turned the wounded Pakura into a Man-Eating Demon, named her Lower Rank Two, and had her fight the Seven Ninja Swordsmen before he battled Yagura Karatachi and Isobu.
- After Blood Moon withdrew, Muzan tasked Pakura with building an arms business and laboratory in the Land of Waves, recruited Kakuzu as a financial adviser, and arranged secret research with Orochimaru.
- Muzan developed an antidote to Chiyo’s poison and fought alongside Konoha forces against Rasa and Chiyo, escaping Rasa’s Gold Dust Burial and helping force the Sand Ninja to retreat.
- When Iwagakure invaded, Muzan pursued research with Orochimaru, advised releasing the One-Tail, and later saved Minato Namikaze from Ebizo’s poison.
- Muzan led medical ninja toward the front, survived Rain Ninja ambushes, and persuaded Konan to have Akatsuki supply Explosive Tags for a share of the profits.
- After learning Kakashi’s team had failed to destroy Kannabi Bridge, Muzan volunteered to lead an elite squad there and knocked Kakashi unconscious to stop him from following.
- Muzan’s squad crossed Iwagakure’s blockade during Shikaku Nara’s feint, and Muzan held off Dong Sǐrén so Hizashi Hyuga and the others could escape toward the bridge.
- Muzan faced the surrounding Stone Ninja alone, striking them with invisible attacks as Dong Sǐrén dodged by leaping onto a tree.
