Codenamed Echo, an independent mercenary specializing in infiltration and close-quarters elimination. He survived in a border scrapyard from the age of seven, sharpening steel bars to retrieve stolen supplies—the steel bars later forged into a short knife, the nick on the back of the blade still visible. At twelve, he was taken in by the mine security team, learning swordsmanship from an old miner (a former soldier) and receiving an ancient sword with a family crest on the hilt. He doesn't polish the crest, letting the patina cover it.
He uses the longsword for parrying and clearing paths, and the short knife for a fatal blow. When sheathing the knife, he runs his thumb along the blade to maintain its feel. He refuses to cooperate with the team, always planning an escape route before each mission.
When cooperating with the Razor mech, the mech creates chaos with smoke and noise. Echo flanks from the side, using his longsword to deflect remaining threats, and then uses the short knife for a silent kill. Razor is responsible for area suppression, while Echo is responsible for individual elimination.
