Soara Habaki, codenamed Arahabaki, is the illegitimate daughter of Chief Superintendent Hideaki Habaki. Her father led a double life as a policeman and loyalist to the organization Bastard Children of Sabaramond. During childhood, he deceived her into becoming a test subject by portraying the laboratory as paradise. For ten years, she endured agonizing experiments as the sole survivor, privately vowing to spare her father if he ever visited. He never appeared, cementing her resolve for vengeance. Her physique bears witness to this trauma: muscular build, short light hair (formerly long brown), and prominent scars including an X-shaped mark on her left cheek, parallel scars over her left collarbone and right shoulder, a stitched abdominal wound, and encircling stitch patterns on both arms. She typically wears laced high boots, trousers, and a sports bra. After surviving the experiments, she became a bodyguard for a Bastard Children sorcerer bearing the Byandy Empire emblem. Her revenge climaxed when her father pursued supernatural events in Shinjuku and confronted them on a rain-lashed rooftop. After her employer revealed her survival and rank, she crushed Hideaki’s wrist, snapped his ankle, and beat him while declaring his pain insignificant compared to her decade of suffering. A sniper’s bullet killed him before she could deliver the final blow. She pursued the snipers, Rinne and Hiro Horojima, engaging them briefly before retreating upon reaching her three-minute mission deadline. Her body contains transplanted organs from a twin-fanged tiger, granting enhanced physical capabilities: feline transformations manifesting as elongated talons, cat-like eyes, and tiger ears; regenerative abilities; and triple-human muscle strength. These unstable transformations demand massive energy, initially limiting use to three minutes before exhaustion risks unconsciousness and triggering intense hunger. Sarabamondian facility records noted erratic performance like unpredictable speed tests, linking her procedures to Byandian assassin methods. Researchers concluded her organs convert mana from food, recommending increased fresh meat consumption. Seeking transformation control and stamina, she trained with the necromancer Corpse God. He identified her tiger organs as originating from his former contracted soul Rwafa and Gwafa, dedosing her body required mana optimization. Through direct mana transfers into her back and dietary adjustments, he stabilized her abilities while she continued missions for her sorcerer employer, facing adversaries like Ikebukuro mediator Gioacchino Soldati. Her companion Lulu, a fellow group member, monitors her condition and communicates with elemental spirits. She remains embedded in the Bastard Children hierarchy under her sorcerer boss while confronting her experimental legacy. She discovered her procedures referenced those used on beings like Teven, a test subject from another world, complicating her origin understanding. Combat encounters in Tokyo exposed other enhanced entities like the Lemmings, fueling her anticipation for future clashes within the city.
