Vol. 7Book - 2008
"As Cooro and company travel through a dark tunnel on the way to Sailand, Husky tells them the reason why he wants to go there--to see his mother. But it looks like the family reunion will be delayed when the children discover that in Sailand, +Anima are kept as slaves! If that weren't bad enough, Husky and Senri get captured by slave hunters! Can Cooro and Nana fly them to freedom?"--P.  of cover.
