In a world where fairy tales are fact and humans live in fear of werewolves, witches, and monsters, only the Hunters Guild can keep the monsters at bay. These red-hooded fighters are anything but little, and only those able to pay a king's ransom can afford their services, but it's a small price to stay alive.

Hoping to join the Hunters Guild, Velou boards the mobile training facility known as the Ironworks. But things aren't all sunshine and rainbows. After three grueling months of nonstop training, he and the other examinees are about to face the most difficult trial of all--the debarkation exam! This time it's a game of cops and robbers, and the ones playing the role of the cops are none other than Grimm and Debonair, leaving the trainees no choice but to run for their lives as the robbers! Velou seems to have a plan up his sleeve, but will the other examinees be willing to trust him?
