After their first successful adventure together, Lizel has officially formed a party with his guard and companion, the famous adventurer Gil. A renowned swordsman known by the moniker Single Stroke for his ability to take down any enemy with just one swipe, Gil has promised to protect Lizel as they become an official part of the adventurer's guild and the two are already making waves!

Lizel's charming personality has earned him a few friends by now, among them a young appraiser named Judge, the grandson of a rich merchant from the mercantile capital of Marcade. When he asks them to accompany him as guards on a trip to visit his grandfather, Lizel happily accepts the opportunity to sightsee and explore in such a famous country. Gil, on the other hand, is more excited about seeing if there are any super-strong monsters to fight in Marcade's Labyrinth. It's time for the newly-formed party to prove their mettle!
