I agree, Koharu's voice is kind of high and sounds kind of funny in the anime...? Koharu is new to the voice acting business so I can't really complain about her voice. She is improving. The OP and ED were good. Animation... pretty good but could be better. Overall...good anime with an interesting storyline.I guess it's pretty cute. The animation kinda sucks. Too much chibi, and the eyes are way too glowy, everything's too exagerated... (To the point that in some scenes, the eyes look like sliced cucumbers. In my opinion.)
I have trouble distinguishing Koharu's voice from Kirari's character. I listen to her and can't help but think "KOHARU". Especially after her perfermance of Rainbow Pink with Sayumi at the Rainbow 7 concert. (Ugh.)
It could be better. It's not horrible. It's cute, just... Could be better, I think.
I'm going to keep watching it, though. So it can't be too horrible. =3
LOL at the Rainbow Pink performance comment.
