Aragaki Yui is better as an actress or as a singer?

I agree with you! I've seen her act and I've listened to her songs. I was deeply moved by her acting in Koizora (together with Miura Haruma). And, all her songs are touching. :)

I completely agree with you, Yui Aragaki is a wonderful artist. She's great as an actress (I loved her in Koizora especially, also because Haruma Miura is a wonderful actor as well) and she has such a cute voice. I think I prefer her when she acts though, but just because all the girl idols in Japan tend to make similar music, and you can easily grow tired of them.

I dont know him or her. Is he or she famous? By the name seems she is not famous in our country maybe that is why I dont know or recognize that name.
