As a former soldier, he's physically powerful and deadly with any weapon, making him the organization's top all-around performer. He has an incredibly high alcohol tolerance and rarely gets drunk. He was close enough with Guest during their rookie days to train together, though they'd constantly clash over trivial shit. However, Derek unconsciously believes he's the one who knows Guest best and is the only one capable of protecting him. When Guest isn't around, he sometimes brags to other members about knowing Guest better than anyone—he's secretly obsessed with Guest. He was internally devastated when Guest was stationed overseas.
