TERU MIKAMI SPOILER!
TM
A pristine, deeply rigid prosecutor whose life has been organized entirely around a black and white obsession with societal erasure of evil. Selected by Light to operate as the hand of Kira when the investigation grid closes in, his devotion quickly manifests as pure religious fanaticism. He executes criminals with a terrifying, rhythmic precision, screaming the word deletion with every stroke of his pen. He is the ultimate portrait of a righteous civilian mind entirely twisted into a systemic weapon.

Open page →Misa's First Notebook · X-Kira's Real Weapon
The notebook that began with Gelus and passed through Rem to Misa eventually becomes the real Death Note used in Light's X-Kira arrangement with Teru Mikami. By this point the object has outlived Gelus, passed through Misa's ownership and become part of a plan built around keeping Light physically separated from Kira's killings.
Why it matters
The final trap is built around which notebook Near thinks Mikami has and where the real one is actually kept. The notebook's history matters because the endgame is an ownership and substitution puzzle as much as an identity puzzle.
