I think the first manga series I began to read was Sailor Moon. But the first series I collected and read all the way through was Chobits by CLAMP. I don't even remember what sparked my interest in manga... probably a friend or someone I admired.
Who introduced me - I knew about manga for a long time before I started reading it. I lived in Hawaii, and the culture there is at least half Japanese. My friends introduced me to Furuba and got me hooked.
My favorite manga was Fruits Basket. I was introduced to it by a friend, who was reading it in class. I picked it up and started reading it, and then also read her second one. Pretty soon, we were trying harder and harder to get the rest of the books. Now we've read up to the ninth one. I think I've kind of lost interest in it, though. sweatdrop
