Arc 2The Portal and the Uchiha
Zongyan uncovered Danzo’s crimes, helped Fugaku rally the Uchiha around the Bloodline Altar, and discovered a portal to the Demon Slayer World. He brought Fugaku and Itachi there to secure resources, while Itachi began learning about the demons and their hunters.
- Zongyan recognized that Danzo’s rogue-ninja mission was a trap, but he and his squad survived repeated ambushes and captured Kawano Shinji.
- Kawano told Zongyan that Konoha’s leadership had seized Kushina’s assets and that Danzo and Orochimaru had experimented on Uchiha, and Zongyan helped fake Shinji’s death and brought him to Fugaku.
- Fugaku convened the Uchiha Jonin, who verified Shinji’s memories and exposed Shisui’s opposition, and Zongyan then revealed the Bloodline Altar and its power to awaken the Uchiha bloodline.
- Zongyan proposed a contribution-point system, and the clan adopted it, increasing its storehouse reserves, and the Altar later awakened three tomoe in Zongyan’s Sharingan.
- Zongyan used his draw to obtain the Multiverse Portal, entered the Demon Slayer World, met Tanjiro, and killed the Hand Demon before capturing another demon to take back for study.
- Zongyan delivered the captured demon to Yashiro at the Uchiha outpost, then returned to Konoha and urged Itachi to keep persuading the imprisoned Shisui to use Kotoamatsukami for the clan.
- Zongyan told Fugaku and Itachi about the Demon Slayer World and proposed using Shisui’s Kotoamatsukami to control Muzan and the demons, and Fugaku agreed to travel through the portal with them.
- Zongyan brought Fugaku and Itachi to Mount Fujikasane, where they agreed to control different countries and collect iron tribute, and Itachi used genjutsu on Yamada Tarō and learned about Japan’s demons and Demon Slayer Corps.
