Stand

A Stand is similar to a persona, except cooler and also not a demon. Probably.

Kin Crimson's abilities include stopping time, being able to erase time leaving only the results but not the in-between (Don't ask how it works, it just does), and seeing time in advance.

Season 3
Strange things happened on Majima and Walter 's match on Season 3 Episode 7, while Majima had the higher hand before, these strange events turned the match around. These events included time slowing down to practically stopping, and the time between Walter beginning his Finisher and the aftermath being erased.

It's believed KC may have been summoned as a demon by an avid Devil Summoner who may have an alliance with another Chaos aligned.
