The film features Mash Kyrielight, a female character who, despite possessing superhuman abilities as a Demi-Servant, consistently engages in and wins physical, melee-based combat against multiple male soldiers and constructs. Her victories are achieved through direct physical confrontation with her shield.

The film adapts characters from Arthurian legend, notably King Arthur and Mordred, who are historically male but are portrayed as female in this adaptation, consistent with the broader Fate franchise.

The film depicts a tyrannical regime led by the 'Lion King,' whose actions are framed by a distorted sense of divine mandate and judgment, evoking a fanatical perversion of Christian-adjacent Arthurian ideals. The narrative clearly condemns this oppressive, genocidal rule, portraying it as a destructive force.

The Hassans, derived from Islamic history, are portrayed as honorable, disciplined, and ultimately heroic allies. Their leader, King Hassan, is a figure of immense power and wisdom who acts justly, showcasing their faith and code in a positive light.
