Himari Kamimura

Kamimura Himari was born to a lone mother in Osaka, Japan. She kidnapped at a young age and tested on with new cybernetics by a local yakuza syndicate Yamanda-Kai in Osaka. The cybernetics used on her were illegal and not used by the general public, custom designed by yakusa tech specialist Tanaka Anno. At the age of 18 she was used as a sex slave for the yakuza leader. Given the bare minimum to stay alive and being the test subject for a number of years second in command hitman Saito Yuta had enough of the group's treatment of her.

Late one-night Yuta sneaked into the bosses' room killing him in his sleep, rescuing Himari in the process. Yuta and Himari went into hiding in Sendai where they were later discovered by the Yamanda-Kai syndicate. After a narrow escape Yuta knew they couldn't run forever so he took it into his own hands to disband the syndicate, leaving Himari in Niigata. Promising he'd return for her, Himari waited for him for 3 weeks, only to hear over traveling news the building once controlled by the Yamanda-Kai syndicate was destroyed with no survives.

Presuming Yuta was dead, Himari came to Tokyo looking for work. Her cybernetic enhancements had made her body into a weapon, making her a capable fighter. She became an independent mercenary for hire at the age of 19. Her history been kept by the yakuza has made her very jaded in her work, being very dismissive for human life. She keeps a memento that was given to her by Yuta as a good luck charm.
