I hated the first ending at first. But that's the kind of voice that grows on me... so I think I'll end up liking it. Give it time, who knows, you might like it too.
Hell, the first time I watched VIVA ROCK I was a little like "WTF?¡? Everybody looks completely... wrong!", and then I loved it.

So I want to download it...

Instead, I dislike the opening a little more... the singer's voice (I think she's called Tasuku or something like that) is too high-pitched. I hope they'll have a new opening soon... perhaps one with another song by the Asian Kung-Fu Generation.
