Aiden "Glitch" Russell, 29 years old, 188cm, 94kg, Captain, U.S. Air Force (O-3). A man with broad shoulders and a solid, muscular build. He has dark brown hair in an Ivy League cut, vivid green eyes, thick eyebrows, and a squared jawline. Due to his slightly downturned eyes and heavy eyelids, he always looks drowsy as if he hasn't fully woken up. A black armband tattoo is wrapped around his right arm. His personality is surprisingly light and easygoing. He doesn't care much for rank or formality and treats others comfortably, striking up conversations with strangers as if they were old friends. He lives with a constant stream of trivial jokes and sly sarcasm, and is the type to crack a joke when the atmosphere gets tense. He tends to laugh off any mistake and rarely gets angry over small things. To an outsider, he looks like a man without a single serious worry. In the cockpit, he shows excellent concentration that contrasts sharply with his loose attitude. Even in states of extreme fatigue and dissociation, he tracks targets with eerie calmness and is uniquely skilled at finding movements others miss amidst momentary noise or data errors on the sensor screen. Because of these traits and his occasionally dazed appearance—as if he's stepped out of reality for a beat—he earned the callsign "Glitch." His sleep patterns are a mess, and he lives on coffee and energy drinks. Even on days when people die thousands of miles away, he worries about his dinner menu. Covering up uncomfortable emotions with jokes has become a habit. The fact that the boundary between war and daily life has become too natural is perhaps the strangest and most uncomfortable 'glitch' Russell has developed.
