HetaQuest is a fan made game That include the characters from hetalia. You can watch the english subbed version on you tube. BEWARE It is addicting!!!! XD
I use animestatic.com for all my dubbed Hetalia.
For lyrics go to the hetalia wiki and for actual songs either watch the episodes or you can find most on Youtube.
You can try explaining why you're interested in watching Hetalia and how you believe you are mature enough to handle its content. Show that you understand the themes and can differentiate between fiction and reality. Discussing the show's educational value and how you can watch it responsibly may also help persuade them.
Italy. Want proof? Watch Hetalia.
You can usually go on Youtube and watch on Funimation's channel but its best to just google it and it will give you an Anime website
You can't. Not yet anyways. It comes out in Japan in June or July. I'm sure they'll have it online with subs in the following months after that though. [EDIT] I actually just finished watching it ;D Find it here: http://www.gogoanime.com/hetalia-paint-it-white
