Abandoned as an infant and raised in orphanages, Bo-Ram Choi grew up learning to adapt quickly to her surroundings. Early caregivers described her as cunning, observant, and fiercely independent, qualities that carried her through her career. Her passion for K-Metal and charcoal sketching, which began in childhood, serves as a reflection of her loyalty to the things that ground her.
Choi enlisted in the ROKA at 18, quickly distinguishing herself as a disciplined and highly skilled soldier. Her exceptional performance earned her a spot in the elite Tarantula Unit, a renowned all-female commando squad specializing in building clearance, hostage rescues, and advanced tech utilization. As her peers moved on, Choi stayed, becoming the protective "big sister" of her unit, known for her unflinching resolve and commitment to those under her care.
Following a tragic mission at Tower, Choi was recruited into Redhammer, where she continues to excel as a tactical leader, bringing her trademark focus and resilience to Rainbow's elite team.
