Do you have the collection already or do you prefer to read/watch online? Since TokyoPop went bust I've seen it in cheap box sets at cons and Forbidden Planet. Wish you could go to comic con with me.
I WAS surprised you like Hetalia! I was a little worried, it's easy to make a mess of political/historical satire, especially in a format like that. What was the first manga/anime you ever came across? I read my mother's cousin's copies of Ironfist Chinmi, then saw the art style in Dragonball the anime at about 9.
