Did you know that if an Anime is popular enough, the voice actors will have fan-meeting event which includes script-reading from their most popular episode? How cool is that?
SAKATA GINTOKI - Sugita, Tomokazu
KAGURA - Kugimiya, Rie
SHIMURA SHINPACHI - Sakaguchi, Daisuke
KATSURA KOTAROU - Ishida, Akira
HIJIKATA TOSHIROU - Nakai, Kazuya
(I was watching an anime about high school boys and was amazed about how one character was voiced. I thought the voice actor was so great and it was the first time I searched for a voice actor. I wanted to hear more from him and it turns out he was Gintoki himself. And that's how I knew and loved Gintama.)
