Cocytus

Cocytus is a Advance Maiden Type Embryo. Cocytus takes the form of a young girl entirely dressed in white, with a white dress and a white ushanka hat. She also has blue eyes. When transformed into her Advance form, she takes the form of an ice armour that covers whatever device Hugo is riding. She has a spunky personality, being unafraid to criticise her own Master or even the leader of their clan.
