Shona Carano, Aristeia! Swordmaster (Submachine gun).
After a brief return to the HexaDome thanks to Final Boss (which consolidated her reputation as an unstoppable and lethal fighter who never compromised herself to fit show-business conventions) Shona would sign a contract with TransEtherea to travel the Sphere in one of their Circulars as head of security. Hers was supposed to be a purely representative role, but a particularly vicious boarding by an Alliance of several Yuan Yuan pirate gangs would force her to take a more active role and wield her sword to defend the passengers. A lethal and resilient contender in close combat, there is no enemy who can resist her great sword.
