Karen Sonomiya

A brilliant mechanical prodigy with an extraordinary IQ of 170, this Master Sergeant serves as a premier expert on advanced machinery. While she possesses unparalleled technical authority, particularly regarding the Sonic Diver B2K1 Fujin, her social confidence falters in the presence of men. This deep-seated shyness makes interacting with boys a significant challenge for her, despite her overwhelming intellectual prowess and specialized role within the military ranks.
