CANON & NON-CANON RELATIONSHIPS.
ROKUDO MUKURO
GAMMAFAG
EIKE KUSCH
Unfriendly. Mr. Psychobob Tightpants. Illusionist. Probable sociopath. Supposedly bases his abilities/powers around the idea of the Six Realms, much like Pein had. Tends to be suspiciously passive, but Kakashi is constantly on the edge around him, nonetheless. Former main priority subject, currently shifted to secondary priority subject, with the sudden reappearance of Uchiha Madara.
Undetermined. Former informant -- things got all fucked up when Kakashi ended up being indirectly responsible for his previous run in with Rokudo Mukuro. Whoopsies. Take one for the team, buddy.
Friendly. Sob. He doesn't even know.
DAI-CHAN
UCHIHA ITACHI
UCHIHA SASUKE
Friendly. Fire Magister. Definitely kind of a dick, but considering the circumstances, Kakashi's turned a blind eye (hurhur) to his former wrongdoings, as he views him as an irreplaceable ally. Gave him a badass rock once. Good times.
Friendly. Former member of ANBU. Not a great conversationalist. Killed him once. Whoopsies -- no, actually, that was on purpose.
Undetermined. Former student. AUUUGH WHAT THE FUCK IS HE GOING TO DO WITH YOU. HOW MANY FUCKING TIMES IS HE GOING TO HAVE TO TIE YOU TO A TREE?
UCHIHA MADARA
UCHIHA OBITO
????
Unfriendly. What a fucking should-be-dead slut. Main priority subject.
Friendly. Former (dead) teammate, the person Kakashi received his Sharingan from, AND THE LITTLE BOY WHOSE GRAVE HE CONSTANTLY VISITS BECAUSE HE'S A GUILTY GODDAMN CLOUD HANGING OVER HIS SECRETLY TORTURED HEAD. /FLIPS PENGUINS
Falalalalalalalalala.
