From anime, not in any particular order:
Xerxes Break from Pandora Hears (Gil is alright too, and my inner psycho loves Vincent)
Kisuke Urahara and Shinji Hirako from Bleach (Yeah, typical anime, berate me for being unoriginal.)
L (Who doesn't love him?)
Takumi Nishijo from Chaos;Head
Takumi Yura and Rei Tezuka from Alive: The Final Evolution (This is a manga, but it's very, very good.)
I don't particularly feel like explaining why I love them all so much. Maybe later, if I get around to it. Right now, I need to be doing other things.
I used to have even less of a life than I do now, so I spent my evenings watching anime and reading manga like the loser I refused to admit I was. I still watch/read it, but only a select few and nowhere near as avidly as I used to.
