Stella Unibell’s uncanny perception of ghosts plunged her into lifelong solitude, branded an outcast by family and society for communing with invisible specters. Accused of triggering the cataclysmic Great Void, she escaped into its depths, seeking refuge among the spirits she understood. Drifting through the Void’s expanse, she forged a fragile bond with Catherine—shattered when Kant, a master manipulator, framed Stella as Catherine’s captor. His deception culminated in Stella’s defeat, her memories fractured and her spirit twisted into a despair-fueled SinWorker. Forced to enable Kant’s massacres, she was ultimately subdued by Lakasha, who purged her most agonizing memories to halt her despair’s spread, exiling her to a new world as a SoulWorker.

Armed with the Howling Guitar—a weapon fused with the demonic entity Fuu-chan—Stella commands spectral wolves in battle, blending aggression with guardianship. She unleashes area-of-effect strikes, conjures healing orbs for allies, and manipulates gravitational forces to trap foes in devouring voids. This duality defines her as both a frontline disruptor and a tactical supporter, dismantling enemy formations while sustaining her team.

Her existence orbits an unending clash between fractured psyche and tenacious will. Lakasha’s memory purge offered rebirth in exile, yet echoes of her ghostly kinship and Kant’s lingering corruption haunt her path. These remnants steer her struggles for redemption, etching a narrative of manipulation’s scars and the fragile hope of reinvention.
