Background / History

A, known primarily as Uchiha Ingetsu (or Yin Yue), served as a captain of the Uchiha Military Police Force in Konoha 9. During the Night of the Uchiha Massacre, rather than quietly submitting to the clan's destruction, Ingetsu chose to defect alongside a squad of Uchiha members 9 10 12. Before leaving Konoha, he assassinated Danzo Shimura, reclaiming stolen Uchiha Sharingan and establishing an independent path for his surviving clansmen 5 10.

Following his defection, Ingetsu traveled across the shinobi world, defeating powerful foes, collecting tailed beasts, and establishing a base known as the Royal Capital Fortress (later renamed the Sky Fortress Manor) powered by the Zero-Tailed's ability 111 112 176. He steadily expanded his influence by forming alliances and tributaries with other villages, notably the Hidden Mist, and taking in powerful subordinates 112 519. As his power grew, he transcended traditional shinobi limitations, confronting extraterrestrial threats from the Otsutsuki clan and navigating temporal anomalies through the Dragon Vein space 247 395.
