and does any one knows how many volumes it has???

You mean Spiral ~Suiri no Kizuna~? =x
Inane scanlates it... http://inane.mangareaders.com/
No idea how many chpaters; I've seen at least six.

Thanks! ^^

I don't think it's complete yet... at least to my knowledge. The anime has completed one season, but since the ending... wasn't great... I think they might be doing another season. Actually, now that I think about it, the ending wasn't really an ending. At all.

YuunaChan, if you read french, you can find it here : http://www.kichigai-project.com

It seems the manga will have 11 books or more

Damn... I really hope theres gonna b a second part of the anime series... cause that "ending" isnt what i expected... I'll pray now... because it would b great to see more Spiral episodes
I forgot to tell u that: im buying the mangas i have 6, but i dont have them all... ill complete the colection trust ME!
