I'm that ever elusive yaoi fanboy. Also, quite a fan of dark, disturbing series. Quite excellent when the two combine. Mysteries and the supernatural are nice. I appreciate good art, and shoujo style really irritates me.
Personality? A loner, pessimistic, artistic, dark, sadistic, intelligent. I guess if you combine L, Light, Ulquiorra, and young Sasuke you almost have me. But add more art and insanity.
I don't obsess over manga, but I do read enough to have a hard time keeping track of it at times. Hence signing up here.
