Belnoa hails from the *Draglius Saga IV* role-playing game as a max-level swordsman fated to overthrow the Demon King. Her design mirrors Dragon Quest III and IV heroines, showcasing green mid-length hair, gold eyes, and battle-ready attire: a blue shoulder pad, single-breast armor plate, purple shirt, and a frayed brown cape. A pride-driven combatant, she relentlessly hunts formidable foes, attacking unprovoked to savor the thrill of battle. Initially convinced the Demon King transported her to another world, she clashes with Nona under this belief. Upon uncovering her existence as a fictional construct, she spirals into denial, reigniting hostilities with Nona despite the revelation.

Her arsenal blends swordsmanship with Freeze and Bind spells, augmented by spectral hands or roots to immobilize targets. She breaches digital realms through screens, pulling allies like Haruto into her quests—a power that fuels her existential crisis after fulfilling her destiny.

Though her rapport with Haruto evolves from rivalry to collaboration, tension lingers, complicated by unspoken romantic feelings. This sparks competition with Nona, culminating in audacious displays of affection, including whispered confessions. Vulnerability pierces her warrior facade when confronted with her artificial origins, exposing raw doubt and sorrow.

A humiliating subplot forces her into revealing outfits, reducing her to tearful defiance—a stark contrast to her battle-hardened demeanor. Interactions with figures like Kusabi and Mikoto probe her grasp of human dynamics, yet combat and duty remain her anchors, even as she navigates fractured purpose and fragile pride.
