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’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.
Chapters 360–384 Vol. 4 Read

Ch. 360Taking on a Student

Shinji kept the Sunagakure volunteer alive to divert attention while Karin fused with the Eternal Mangekyo Sharingan, and the rumors stirred tension throughout Konoha. As Karin’s fusion neared completion, Kakashi gathered Jonin to find a mentor for Shinji.

  • The Ninja Academy students discussed the surviving Sunagakure transplant volunteer as Konoha and the other villages remained silent and wary.
  • Yakumo worried that reports of another successful transplant would encourage more people to undergo the dangerous operation, and she walked away without answering Shion.
  • Shinji explained to himself that the volunteer had not fused with the First Hokage cells and survived only because he kept drawing out the volunteer’s rampaging Yang Release Chakra.
  • Shinji sent the extracted chakra to Karin, whose Eternal Mangekyo Sharingan fusion was seventy to eighty percent complete after three weeks.
  • Kakashi brought several Konoha Jonin to watch the students and hoped one of them would take Shinji Uchiha as a student.

  • Kakashi proposed that the Jonin select promising students, but Asuma, Shizune, Kurenai, Guy, and Yamato explained their existing commitments or declined to choose Shinji Uchiha.
  • A week later, Asuma, Kurenai, Shizune, and Yamato began training their assigned students, while Rock Lee also found a Jonin to teach him.

  • Shion told Shinji that her Jonin trainer had agreed to practice with him and said she would claim the Jonin had chosen him himself.

Ch. 362The Attack

Shinji worried that the village’s failure to assign him a Jonin instructor had sparked rumors, while he continued preparing for Karin’s next procedure. An explosion at Konoha Hospital revealed an attack on the surviving Sunagakure volunteer, and Shinji decided to let the man die in a way that looked natural.

  • Shinji kept a low profile as rumors spread that Konoha’s leadership had rejected him, and the Ninja Academy expelled several students for spreading them.
  • Kakashi assured Iruka that the village was not targeting Shinji and had simply not found a suitable instructor for him.
  • Shinji went to Konoha Hospital to work on formulas for Karin’s future procedures and noticed unfamiliar people in the corridors.

  • Karin opened her eyes, confirmed she could see clearly, and activated her Eternal Mangekyo Sharingan herself.
  • Karin told Shinji that her left eye had awakened Amaterasu and her right eye enhanced Susanoo.

Ch. 365Exposed Weaknesses

After testing Karin's Eternal Mangekyo Sharingan, Shinji realized that both her eyes and his own still had room to grow, and he decided to strengthen Karin's Yang Release Chakra with First Hokage cells.

Ch. 373Watching the Battle
