The ninja. When this word comes to mind, one thinks of a speedy black-garbed man wielding poisoned needles, swords, and shurikens. Shu fits this description except for the equipment options: just replace "poisoned needles, swords, and shurikens" with "Guns, time bombs, and boots to the face".
Shu, like his protégé Elc, is a hunter. This means he gets any job done, whether its finding lost puppies or stopping rampaging madmen. Shu doesn't have the personal involvement with Romalia that his comrades do, but that doesn't mean he won’t help out his friends in times of need. Shu is a force to be reckoned with, both on and off the battlefield.
In the DL, Shu has a record as one of the most snubbed characters in its history. Having been nominated for entry since Season 2, he finally got his chance to show his stuff in Season 18... only to run headlong into his worst opponent class. Still, despite a bad record, Shu has the power to put his foes down. With status-inflicting weapons, speed, phenomenal physical durability, and the dreadfully powerful Time Bomb skill, he can lay waste to most foes long before they have the chance to do the same to him.
