Arc 15Karin’s Susanoo Trial
Shinji tested Karin’s newly awakened Eternal Mangekyo Sharingan in an attack on Konoha, where she fought Yakumo and revealed a Complete Susanoo. He later transplanted First Hokage cells into Karin, who assimilated them and gained the Power of All Things, while Shinji began watching for signs that she might awaken the Rinnegan.
- Shinji let the surviving Sunagakure volunteer die during an attack, then completed Karin’s Eternal Mangekyo Sharingan fusion and implanted her eyes in Fugaku Uchiha.
- Karin raided Konoha’s Archives as Akatsuki’s “B,” testing her Eternal Mangekyo Sharingan, stealing sealing scrolls, and provoking Sasuke.
- Karin’s Complete Form Susanoo battled Yakumo and Konoha’s forces, while Shinji watched the test and Karin escaped without killing anyone.
- Shinji recovered the Adamantine Sealing Chains and Four Symbols Seal scrolls from Karin, then concealed her identity and prepared her for a First Hokage cell transplant.
- After a week of preparation, Shinji began the transplant, and Karin endured the rampaging Yang Release Chakra rather than let him stop the procedure.
- Karin’s Eternal Mangekyo Sharingan strengthened, allowing her to balance Yin and Yang Chakra, assimilate the First Hokage cells, and produce the Power of All Things.
- Shinji taught Karin to use a Four Symbols Seal to contain her increased Chakra, then cleaned the cave and reviewed the risks of his own future transplant.
- Shinji decided to track Karin’s Spirit Body for signs of Rinnegan awakening and hoped to harvest her Power of All Things with Magatsu.
