Yin's standard armor system, designed to function with most frontline weapons in use. Her personal configuration is outfitted around gunblades. Noteworthy features of the MAS include the carbon-fiber shell and fabric weave sections; anti-magic surface coating for much of the shell armor; and the "breakout" system, providing the ability to disengage multiple segments of the shell and fabric weave sections in the event that some malfunction or loss occurs with the primary weapon.
