アルファルド

The series' most prominent villain, Alphard is an attractive young woman who is both the leader of a terrorist organization called Snake and Canaan's arch-enemy. She appears easily capable of taking down Canaan even though the latter uses her synesthesia, reasoning that she is no longer manipulated by feelings unlike Canaan. She carries a FN Five-seveN USG as a sidearm.
