Zatch Bell! - Vol. 12

Blurb:
During the course of their many battles, Zatch and Kiyo have chanced upon several mysterious stone tablets that closely resemble mamodo. As it turns out, during the last fight to determine the king of the mamodo 1,000 years ago, one mamodo had the power to freeze his competition in suspended animation. Now, someone has discovered a way to reanimate these stone tablets, and that spells mega-trouble for Kiyo and Zatch - especially since they're now terribly outnumbered!
