Arc 4The Uchiha World
Seiichi returned from Moryo’s Sealing Space with immense new power as the Uchiha’s conflict with Konoha and the Land of Fire escalated into war. After taking control of the clan and destroying its rivals, he presented the other clans with his plan to unite the nations under one shinobi world.
- Seiichi absorbed the Sealing Space’s evil energy, spent years transforming, and emerged with an Eternal Mangekyō Sharingan and a silver-black Rinnegan.
- Utatane Koharu’s tax seizure of the Uchiha factories led to a dispute over the clan’s reduced tax rate, and the Utatane Clan paid Fugaku 5.5 billion ryo in compensation.
- After the Uchiha announced their wealth and warned against attempts to claim it, Raimei led raids on the Fire Daimyo’s capital that killed the Daimyo, Asuma, and others.
- Seiichi returned, took over as Uchiha Clan head, and rejected Hiruzen Sarutobi’s demand to hand over the attackers, while the other nations prepared to declare war on Konoha.
- Seiichi captured nearly three thousand Sarutobi clansmen, killed Hiruzen, and had the Uchiha capture Minato and Jiraiya as he declared his plan to create a single nation.
- Shisui used Kotoamatsukami on Tsunade and treated her fear of blood, while Seiichi led the Uchiha in wiping out the Sarutobi, Utatane, Mitokado, and Shimura clans.
- Seiichi appeared before the assembled clan representatives and explained his plan to unite the nations, create a unified ninja academy, and improve living conditions.
