Ryo is living his best second life in Phi and doing as he pleases. Ever the adventurer, he accepts an escort job for a merchant heading to the Principality of Inverey. Unfortunately, he forgot to withdraw money before leaving the Kingdom of Knightley, so he finds himself at a complete loss in its capital and penniless in a foreign land. In order to return to Lune where all his friends are, he takes on another escort mission, this time back to the Kingdom of Knightley...or so he thought! The job actually has him acting as the body double for a prince being targeted by assassins, but then the real prince ends up kidnapped anyway?!

A major power's ulterior motives and the real reason the prince is being targeted lurk in the shadows. However, to each and every problem that falls in his lap, Ryo's solution is always simple: "I'll bury anyone who gets in my way in the permafrost!" The adventures of the strongest freewheeling water magician continue in this frenetic third volume!
