Okay, not so breaking. Just call me slow, but I went back to doing research on Spiral: Suiri no Kizuna and when it'll come out. Turns out, just a little snooping, will help ya find a lot.
Here's the Yen Press Site. I'll link it up at top, too.
SPIRAL: The Bonds of Reasoning, Vol. 1
Story by Kyo Shirodaira | October 2007 | ISBN: 978-0-7595-2341-8 (0-7595-2341-X) | $10.99 ($13.99) | 5" x 7 1/2" | 192 pages | Teen
That's for the first volume only. They had a second volume information too.
Spiral Vol 2 | January 2008 | ISBN: 978-0-7595-2407-1 (0-7595-2407-6) | $10.99 ($13.99)
By the looks of that, it seems the books will come out every 3~4 months. That's okay, but since I've watched the anime, I'm dying to know what happens after that storyline [which is like book 4 or something, I think] It'll be years til I'm okay with the story. It's kinda like Fruits Basket. Except I'm hoping Yen Press will have better quality. 'Spiral: The Bonds of Reasoning' is a good translation of it. The anime was called Spiral: The Melody of Logic. They're both good, but the anime never answers the unanswered questions.... WAHH~~!!
Finally, though, the manga has been licensed and will finally come out.
