Noelle Silva, youngest daughter of the Clover Kingdom's royal House Silva, endured lifelong ostracization and mockery from her siblings—Nozel, Nebra, and Solid—who blamed her for their mother Acier's death during childbirth. This treatment fostered deep-seated insecurity, anxiety, and an inferiority complex, initially masked by a noble facade of arrogance and vanity. Her early interactions were marked by difficulty admitting failures and deflecting blame. Rejected by her family and denied entry into the Silver Eagles, she found acceptance with the Black Bulls squad. This proved a turning point, as the squad's support, particularly Asta's unwavering resolve, gradually bolstered her confidence. Early missions revealed her unconscious restraint in magic due to a fear of harming others. A child's plea for protection during the Saussy village attack triggered her first controlled spell, the defensive barrier Sea Dragon's Nest. Subsequent growth saw her overcome mental blocks, shifting from defensive to offensive capabilities, notably during the Underwater Temple arc. Tools like a wand and a brooch housing Bruce, a magical lifeform aiding control, further improved her magic. Her water magic evolved significantly. Initial spells involved basic manipulation like Sea Dragon's Water Ball. Training in the Heart Kingdom unlocked True Water Magic and Mana Method, enhancing spell size and power. She developed Creation Magic, forming water-based entities like dragons, and Reinforcement Magic for physical boosts. A breakthrough came with Valkyrie Dress, full-body armor granting flight, a lance weapon, and heightened offense/defense, later including a Mermaid Form for underwater combat. Temporary contracts with spirits amplified her abilities: Undine enabled Spirit Dive (Saint Valkyrie Dress) and Saint Stage, allowing her to purify devils and defeat Vanica Zogratis while destroying Megicula's heart. After Undine's departure, she contracted Leviathan, the Sea God, gaining Valkyrie Armor Dragon Form and further power escalation. Key battles demonstrated her progression: against Vetto at the Seabed Temple, where she first used offensive magic to protect allies; in the Witches' Forest, where Asta's encouragement helped her defeat Fana; during the Royal Knights Exam, overpowering her brother Solid; and in the Spade Kingdom, vanquishing Megicula with Nozel's aid. Post-timeskip, she battled Lucius Zogratis and participated in defeating her mother, resurrected as a Paladin. Relationships defined her arc. Familial ties were fraught, especially with Nozel, who secretly protected her by withholding their mother's curse truth. Within the Black Bulls, Asta's influence fostered courage and self-worth, though she struggled to admit romantic feelings for him. Bonds extended to allies like Kahono, who noted her protective nature, and cousin Mimosa Vermillion, a romantic rival. Her growth included rejecting class prejudice, notably comforting a commoner child during the Star Awards Festival. Physically, she possesses silver hair, pink eyes, and a slender build. Early attire featured a purple dress, silver blazer, and Black Bulls robe. Post-Heart Kingdom training, her robe was modified with a turquoise neck cord, and she adopted purple hair ribbons. Her Valkyrie Dress appearances evolved with each power-up, incorporating wings, halos, and dragon motifs. She also appears in the film *Black Clover: Sword of the Wizard King* and the game *Black Clover: Quartet Knights* as a playable character.
