See, this is why I dropped out of school, never teach you the good stuff.
We do, and there are others besides. Slayers actually make up the huge minority of demon/vamp hunters- most are folks who have lost something or someone.
Vigilante huh? Actually... ok, cards on the table time? I kinda have an... interesting criminal record. I may have, sort of, killed someone. By mistake. (he walked into the middle of a fight and I staked him before I realized he was human) Covering that up kinda led to me doing other stuff before I eventually confessed. It was Angel who kinda saved me in that sense. I guess.. I went a little crazy for a while, thought that being a Slayer meant the rules didn't apply to me. But being a Slayer kinda meant they applied more.
So that's kinda the story that is me. Hope it's not all too weird and freaky to deal with. I know this whole situation must seem.... totally insane to someone who's new to it all- shoulda seen my freakout when I was first Called.
A will to survive should never be knocked- can keep you alive when all else fails.
