Fitoria, Queen of the Filolials, upholds a centuries-old mandate as guardian of her species and the world. Raised by the Shield Hero Mamoru Shirono, she enforces his final wish: ensuring collaboration among Legendary Heroes against the Waves of Catastrophe, even by eliminating uncooperative heroes to summon replacements. Her 500-year lifespan, tied to Filolial biology and speculated links to the enigmatic Red Poison, underscores her enduring duty. In human guise, she manifests as a silver-haired girl with light-blue streaks, crimson eyes, and a red-and-white gothic lolita ensemble paired with white silk boots. Her true Filolial form towers at 100–200 times standard size, adorned with snow-white plumage, azure-tipped neck feathers, and golden crown-like crests. She shifts her size strategically, from disguising as an ordinary Filolial to confronting colossal foes like the Spirit Tortoise. Regal yet eccentric, Fitoria blends authority with Filolial traits—forgetfulness, voracious appetite, and draconic antipathy. Jaded by mortal conflicts, she maintains emotional detachment, prioritizing world balance over individual lives. Though ruthlessly pragmatic in culling discordant heroes, she extends measured compassion to cooperative allies like Naofumi’s party. Her powers span dual-form transformation, size manipulation, and mastery of ancient magic. The Vassal Carriage weapon enables teleportation and devastating charges, while her spellcraft includes protective barriers, speed augmentation, and wind assaults like Liberation Wind Prison. She imparts critical wisdom on Waves and Legendary Weapons, unlocking specialized shields for Naofumi and enhancing allies’ class advancements. Spin-off narratives reveal her mentoring trio of Filolial successors—Sakura, Yuki, Kou—while warily navigating interactions with the erratic Spear Hero Motoyasu and his Dragon Spear’s Minute Hand. Across timelines, she steadfastly honors her master’s legacy, confronting time loops and interdimensional crises. During the Spirit Tortoise conflict, she orchestrates the core’s destruction alongside Naofumi, battling the regenerated behemoth to showcase tactical prowess and selective collaboration. Her storied past includes vanquishing the Dragon Emperor and Griffin King, safeguarding hidden ruins and populated lands. A pivotal bond with Filo emerges through a test of strength, marking Filo as heir apparent. Their mentorship involves transferring power and knowledge, reflecting Fitoria’s succession preparations. Beneath her aloofness linger flickers of vulnerability—nostalgia for her master’s meals, frustration at fragmented memories eroded by time’s passage.
