I've read the manga, but is the novel worth it?

Yes. It's quite good. :]

It was alright...the manga was so much better though -- no doubt.

I have to agree, the mangas were better- but the novels are CUTE X3 I did enjoy reading them. And they're an easy read, too, which is nice. Some of the books are so well-written that half the time I have to read something over 5 times if I'm really out of it. Gravi novels... they're just cute :3

It was pretty cute. I did like teh manga better.

I didn't think they were all that good. It was basically a fanfiction.
Actually, I've read some substantially better fanfiction.
The manga were about a thousand times better, IMO.

its good it tells more about them
