Hideaki Habaki, a police superintendent, led a double life as a devoted agent of the Bastard Children of Sabaramond, a secretive group conducting supernatural experiments. He surrendered his illegitimate daughter, Soara Habaki, to the organization as a child test subject, deceitfully promising her a paradisiacal environment. For ten years, she endured relentless, brutal trials, emerging as the only survivor. Though she secretly vowed to spare him if he ever displayed concern, Hideaki never visited, prioritizing his clandestine duties over paternal ties.  
Publicly, he mourned his “deceased” daughter Miyabi Hosorogi, masking his role in her murder and his true loyalty to Civil A. Sabaramond, a pivotal leader within the Bastard Children. His police authority became a tool to covertly advance the organization’s goals, blending bureaucratic influence with subterfuge.  
His reckoning arrived when Soara, now codenamed Arahabaki, confronted him during a mission. After revealing her survival, she subdued him, poised to avenge her torment. Before she could strike, he fell to a sniper’s bullet from Clarissa, an operative of a rival faction. His death sealed his legacy of betrayal and manipulation.  
In the Corpse God’s temple, his summoned spirit faced scrutiny of his memories—particularly his sacrifice of Soara. Supernatural observers condemned his deeds, inflicting magical retribution as final penance.  
Psychologically classified as an INTJ and Enneagram 8w7, Hideaki embodied strategic precision, emotional coldness, and an unwavering focus on organizational supremacy, rendering familial bonds expendable in his pursuit of power.
