As of today, Hei has moved past the end of his canon. This means several major changes, both in his lifestyle and in his personality. So, to sort it out (both for myself and everyone else) I've decided to write down just what exactly I think those changes are. This is, admittedly, a lot of headcanon, but it's all been influenced by a couple of clues left for us at the end of the show in terms of what Hei's future is going to be like.

MAJOR SPOILER WARNING.

( The man named Li is dead. )
