The Clockwerk parts have been stolen! And not by the Klaw Gang! The info on the crooks who made off with the parts leads them to Death City, where our favorite gang of thieves must team up with DWMA if they want to defeat Arachnophobia and the witch Medusa! But what happens when two clans familiar with each other come face to face? Hurt? Anger? Friendship? Or even Jealousy?

Wounding up in Death City by an accident in his world, Sly Cooper is aided by Shibusen to get him home. Plus, in this world, he can turn into his family cane and have the abilities to devour Kishin eggs. Because of this matter, Lord Death made him a student at the academy during his stay... and Maka Albarn now has an anthropomorphic raccoon as her second partner!
