My name comes from a move from a character named Kurapika in an anime called HunerxHunter. He's my favorite character in the series because his past if pretty fucked up and his Chain Jail ability is the coolest shit I've seen in anime in forever.
Anyways the ability in question "Emperor Time" is when he becomes proficient in all categories of nen. Nen is basically aura that you can manipulate and there are 6 categories. I won't go too deep but usually someone can only be proficient in one category at a time and the other categories next to your most proficient one are the ones you can somewhat use. However, Kurapika comes from a race of people who's eyes turn scarlet when they become filled with strong emotion. So basically his eyes turn red and he becomes fucking jesus.

here is the nen chart, Kurapika was a Conjurer. His nen ability allows him to conjure nen chains. He has one chain for each finger on right hand. Each chain does different things.
Sorry for going a little in detail, he's fucking bad ass.
this is what he looks like.
