Toki Asuma is a reserved, duty‑bound student and elite fighter from Blue Archive’s Millennium Science School. Genetically enhanced and trained, she serves as Rio’s personal protector, wielding an assault rifle and specialized exoskeleton. Emotionless exterior hides deep loyalty and desperation for purpose. Her life revolves around service, with social skills underdeveloped due to isolation. In rare moments, she shows subtle warmth and dry wit, especially around her sensei or trusted comrades under stress.
