Jujutsu Kaisen Chapter 166

The shadows come alive. Megumi unleashes everything — Rabbit Escape swarms to blind, Divine Dogs to harry, Nue to strike from above — a symphony of shikigami conducted by a dying boy who refuses to stop. Reggie, for all his centuries, has never faced anything like the Ten Shadows wielded without restraint.

Yet Reggie endures, recreating counter after counter, and the terrible truth settles in: Megumi can’t win this fight. He can only end it. His hands begin to move into a familiar, forbidden pattern — the summoning ritual he once threatened Sukuna himself with. Jujutsu Kaisen Chapter 166 ends with Reggie’s grin fading as he realizes what those hand signs mean.
