Ch. 421Regeneration Surgery
Plot points and events
- Kagami Uchiha returns from a mission and reports to Kazemori Masaki, who arranges the long-awaited regeneration of his missing arm.
- Tsunade leads a team performing the Healing Resuscitation Regeneration Technique, a complex, multi-person procedure that uses Kagami’s own cells and requires careful chakra coordination. Kagami is anesthetized, and the operation proceeds.
- While the surgery is underway, Kazemori, Utatane Koharu, and Mitokado Homura discuss leadership in the Medical Department. They consider transferring its headship from Koharu to Tsunade, with Koharu serving as an adviser.
- The conversation expands to Konoha’s future administration. Kazemori proposes giving younger people positions to build experience and exploiting the war’s end to pressure nobles who have obstructed the village. His plan could also let Konoha acquire their lands and recruit their samurai.
- The operating-room light goes out, signaling that the surgery has ended; the chapter does not yet reveal its outcome.
Character developments
- Kagami is eager to recover and trusts Tsunade’s skill, accepting anesthesia and the lengthy procedure without hesitation.
- Tsunade is shown as the Medical Department’s leading innovator and an authoritative, careful surgeon, directing the team through a high-stakes operation.
