Summary
Ginka serves as the Sacrifice Unit within the duo known as Sleepless, a title shared with her partner Kinka that signifies their nature as individuals who do not require sleep. The pair made a swift appearance in volume 2, where they were defeated by Soubi. Following this loss, they were forced to surrender the envelope containing crucial information to Ritsuka. While they functioned as a competent team, they lacked the capability to overcome Soubi in combat. It is suggested that even far in the future, they might only achieve a tenth of Soubi’s individual power.
