Hilda
Hilda doesn't seem to have been in the military prior to joining the Gekkostate, but she's a natural lifter. This combined with her quick thinking has made her the best LFO pilot not part of the original group. She often pilots the 808 Terminus, and uses its heavy firepower and armor in a defender role. There is no mention of her actually being married to Matthieu, but they act like husband and wife.
