Serenity
DeadlyComposedEnigmaticMerciless
A deadly and enigmatic Assassin-class Servant from the Fate universe, Serenity is a master of poisons and infiltration, her petite form belying the lethal grace that courses through her veins. As one of the many incarnations of Hassan-i-Sabbah, she is a cold-blooded killer who shows no mercy, yet beneath her icy exterior lies a yearning for true serenity.
