This article is about the Quirk. For the Quirk's user, see Hari Kurono.
Chronostasis grants the user arrow-shaped hair that can extend itself in a straight line and cut others, slowing down targets if hit.
The "Minute Hand" is located at the front of Hari's hair, above the forehead. The "Hour Hand" is located on the back of his head around the nape. The duration of the slowdown effect correlates to the unit of time represented by the hitting hair arrow.
Hari is incapable of using his Quirk while in motion, so he needs to remain motionless for his hair to extend.
