Appearance: A humanoid with a muscular white body, exposed gums, and a slightly hunched posture, standing at a massive height of 3.5 meters. Instead of eyes, two pairs of wings grow from its eye sockets. Atop its head, which extends like a snake's tail at the back, floats a wheel-like dharma crest representing the Eight-Handled Sword, symbolizing "perfect circulation and harmony." A sword is bound to its right forearm with bandages. It wears tattered black hakama on its lower body. It has exposed gums and possesses a mouth and lungs, but lacks vocal organs, making communication through speech impossible. Its existence is pure "abnormality," and ordinary humans are rendered immobile by fear. It cannot speak. Physical Ability: Its basic means of attack are martial arts and melee combat, but its monstrous physicality alone is a more than sufficient threat. Its vitality is extraordinary, allowing it to continue fighting even if reduced to a single leg, a single arm, just an upper body, or even just a head. It boasts incredible physical prowess, such as blowing a human away over 400 meters with a single strike and immediately following up. Furthermore, simply inhaling and exhaling air creates a cannon blast several times more powerful than an artillery shell, and its arm strength is enough to pierce through piles of concrete as if swimming through them. Sword of Extermination: A sword specialized for anti-monster use equipped on its right arm. It is a mass of extremely compressed energy, and any substance composed of cursed energy or magic power it touches is obliterated in a single strike. It can also easily destroy attacks or constructs made of magic power with lower purity than the sword. Additionally, after adapting to barriers constructed by seals or Domain Expansions, it can destroy them in a single blow by thrusting the sword into the wall. Ability: "Adaptation to all phenomena." It acquires resistance to attacks it has taken or defenses that have blocked it, and devises more effective offensive and defensive measures according to the opponent's state and nature. When it begins to take an attack, the wheel on its back turns 1/8th of a rotation with a "clack," fully recovering any physical damage sustained up to that point while adapting to the attack. Adaptation is completed over time after receiving an attack, but additional contact with the target of adaptation during that interval shortens the time required. It may adapt to the technique itself, or to the method of attack and the attribute itself. If it is not defeated, it will recover, making it extremely difficult to defeat using that technique or method. It is difficult to observe the stages of adaptation from the outside or decipher the nature of the ability; one can only check by striking with a technique, but even a single probing strike will grant it intense resistance, leading to a stalemate. Furthermore, if the combat time is prolonged, it adapts to the opponent's "existence" itself, rendering any and all arbitrary attacks ineffective.
