The vibrant world of Britannia is filled with legendary warriors, complex magical systems, and deeply compelling storylines. While the primary chivalric order consists of diverse heroes, the female characters in this universe stand out due to their incredible resilience and unique magical capacities. Evaluating these individuals involves looking at both their raw combat potential and the distinct temperaments that define their actions throughout the narrative.

Merlin the Ultimate Mage of Gluttony

As one of the most brilliant magical minds in fantasy history, Merlin possesses the unique ability known as Infinity. This extraordinary gift allows her to keep any spell active indefinitely without consuming additional magical reserves. Her personality is defined by an insatiable thirst for knowledge, which often makes her appear detached, calculating, and somewhat mysterious to both allies and enemies.

Despite her cold exterior, her loyalty to Arthur and the survival of Britannia remains a driving force behind her complex strategic maneuvers. Her sheer versatility in battle makes her arguably the most versatile and dangerous female figure in the entire franchise. By combining strategic planning with absolute magical dominance, she easily secures a top position among the realm's elite protectors.

Elizabeth Liones the Reincarnated Goddess

Initially introduced as a vulnerable princess searching for salvation for her kingdom, Elizabeth eventually awakens to her true heritage as a high-ranking member of the Goddess Clan. Her combat strength is largely defensive and restorative, capable of neutralizing dark miasma and healing fatal wounds instantly. Her personality radiates pure empathy, kindness, and unwavering determination, even when facing apocalyptic threats from ancient demonic clans.

Her quiet resilience serves as the emotional anchor for the entire group, proving that true power extends beyond physical destruction. She is willing to confront supreme deities to protect those she loves, showcasing immense mental and spiritual fortitude. This unique blend of supreme holy magic and absolute compassion renders her an indispensable force in the battle for Britannia.

Diane the Giantess of Envy

Representing the powerful Giant Clan, Diane wields the inherent power of Creation, which grants her total mastery over the earth and mineral formations. She can manipulate tectonic plates, summon massive stone spires, and increase her physical durability by shifting her bodily composition. Her personality is characterized by a fierce protective instinct, deep emotional sensitivity, and a vibrant zest for life that contrasts with her intimidating physical stature.

Over the course of her journey, she overcomes deep-seated insecurities to become a proud and self-assured warrior queen. Her physical might is balanced by a gentle heart that values deep friendships and emotional connections above all else. This combination of raw geological destruction and heartfelt dedication makes her an incredibly well-rounded champion on the battlefield.

Derieri the Unwavering Purity

As a prominent member of the elite Ten Commandments, Derieri commands immense respect due to her brutal physical combat style known as Combo Star. Each consecutive blow she lands adds tremendous weight to her subsequent strikes, making her nearly unstoppable in close-quarters engagements. Her external demeanor appears silent, aggressive, and deeply untrusting, a direct result of past tragedies suffered during the ancient Holy War.

Beneath her rough exterior lies a deep capacity for loyalty and a desire for peace that eventually guides her later decisions. Her evolutionary character arc demonstrates that true strength includes the willingness to reevaluate one's path and seek redemption. Her explosive combat abilities and nuanced psychological development make her one of the most memorable antagonists turned allies in the series.
