Here's something I thought would be of interest to everyone. I found a Blog for Aya Matsuura. She's the lead actress in Anza's Musical, "Only You".
She mentions Anza a lot on her Blog and even posted 2 clips from youtube. The first was Kanata E and the second was Chain. She writes in one entry how important Anza's role of Ayako Honma is to this show. She plays the best friend of the lead character.
I don't have the time to translate the Blogs about Anza into English, but I hope you click the link anyway and check this blog out.
