It.. depends?
On my mood, I mean, or maybe who I'm around.
I probably come off somewhat like Naoto from Persona 4 to some people, if I'm by myself in public, or around people that I'm not comfortable with.
For the last year or so I've sworn up and down that if me and everyone that I know all poofed into some world where we were anime characters, I'd end up as Otonashi from Angel Beats. The only difference between me and that character at all, if you squint really hard, is that I have times where I get more energetic than he gets. Normally due to coffee. or booze. 8D;
Also, I have some people tell me that I'm like Zelos sometimes, from Tales of Symphonia. I don't complain since he's my favorite Tales character. hurr.
