Front-line Commander and head of the Third Quadrant Division, Cassandra sees the civilian fleet as a hindrance to the Mazone military and argues that they should be abandoned to their fate after an attempt to protect a passenger ship (which Harlock mistook for a command ship) causes her fleet to lose to the Arcadia. Revising her tactics, Cassandra places the civilian ships in the front line of battle to shield her fleet from attack, but is ultimately defeated when Harlock uses a diversion to draw off the rest of her battleships and flanks her command ship, leaving Cassandra alone to swallow the bullet (or blade, as it were.)
