Chunin Exams
Misumi attempts to use Soft Physique Modification on Kankuro during the Chunin Exams by catching him in an inescapable hold and breaking his neck.

He, like Yoroi, has taken off the cloth covering his lower face. During the events of this arc, Ino Yamanaka uses her Mind Body Disturbance Technique to force him to tie his arms to pillars in one of the rooms of the labs, and leaves him there when it collapses, presumably killing him.
