In a world where the spirits of humans manifest into physical tendrils known as Bonds, a ragtag group of friends literally AND figuratively fuse by the souls.
Enter Bond League Beta Kaiza, an opulent academy of intellectuals with hundreds of different soul types. Cindy and her pals aren't anything special, with bonds that serve more as conveniences than spectacles. That is, until Cindy meets Tristan, a geeky honor roll student with no bonds of his own. As the two discover that they make better friends than they had anticipated, the magnitude of their union turns the city of Aeronpolis on its head.
