My first anime was Princess Tutu(This was before I knew what anime was! Still my favorite one EVER!), and my first manga was Yumeiro Patissiere. Such a good manga! The anime is totally different
Spirited Away was my first anime ever, before I even knew what anime was... As for 1st manga, I don't quite remember... Probably a Yaoi one ;) Junjou Rom. it was, perhaps? It was a looong time ago. reply
