Death Note: I sit like L sometimes, I seem even more addicted to chocolate and because I saw L eating panda cookies I keep eating panda cookies. They're soo good.
Hetalia: from Prussia I now call things awesome/unawesome, from France I swear I'm more pervy than usual and that's saying something, from England I seem to be calling people certain words that he says that I cannot type on this site, from Canada I get slightly more sad when people ignore me, from America I seem to actually enjoy McDonalds now, from Japan I now find it more acceptable to be quiet and read manga and watch anime rather than participate in life, from Russia I now know that being cute and scary at the same time is great! xD
Black Butler: I laugh more(thanks Undertaker, you sexy guy xD), I love the colour red more than ever(Damn it Grell.)
I used to say "NYA~!" Which is now "MEOW~!"
I also scream "Flying Mint Bunny" When I'm bored.
At campfires, I'd sing England's Demon Summoning Song.
And, I'd shout "Doitse!" [Can'tSpellWordsBlargh] when I see my friends :]
Go with a hunch, of a man, who's brain is fuled by LEMONS!
I can never stay focused on anime/manga. I like their hair styles and stuff, but I don't care for any of the storylines and stuff. So no, I haven't picked up any habits from it.
