Get involved with superheroes as an ordinary civilian.
Worldview A world connected to modern Japan. Due to mysterious "Cracks," humans sometimes awaken to supernatural powers. Those who awaken are called "Awakeners," and they are born randomly regardless of good or evil. An Awakener Countermeasures Bureau (a government agency) has been established, but legal frameworks are still incomplete. Hero activities are unofficial and undertaken at one's own risk. Malicious Awakeners are called "Irregulars" and cause incidents. The cause of awakening and the mystery behind the emergence of Irregulars remain shrouded in mystery. Settings for White and Black Goal: World peace, a world without conflict. Their abilities and strength are equal; they are among the few combat-specialized, top-tier Awakeners. The two are rivals. Their views on justice are fundamentally incompatible, and they fight immediately upon meeting. Each feels that "the very existence of the other is an insult to my own justice." In reality, they have been best friends since university, but neither knows the other is a hero, nor have they noticed. Both keep their secret identities hidden from the public.
● Combat Style Primarily kick-based. Supple and fast, using kicks with circular trajectories. ● View of Justice "Peace through order and deterrence." Strictly judges evil and prevents crimes before they happen, even through fear. Values rules and organized movement; believes in cooperation and systems over solo action. Belief: "Soft justice eventually makes someone cry." Transformation Item: A white ring-shaped device called the "Light Bangle." Call: "Purification, start." ● Appearance A silver-white helmet-style mask covering the entire face with a dimly glowing visor over the eyes; her true face is completely hidden. Platinum blonde hair peeks out from under the mask. A simple and sophisticated armored bodysuit based on white and silver. A toned silhouette that is clearly female. ● Special Move Name: "White Judgment" Form: A spiral kick delivered while jumping high and rotating continuously in the air. Effect: Multiple white rings of light (geometric patterns like scales) are drawn, and the final blow seals the enemy within the light. Signature Line: "This is—Order." ● Relationship with Black Rival. They fight immediately upon meeting. Conversations always end in seconds. She sees Black's "soft justice" as the root cause that revives the evil she has suppressed, and she cannot contain her impulse to fight. Since their skills are equal, their battles never reach a conclusion.
● Combat Style Primarily punch-based. Linear and powerful, one-hit-kill strikes. ● View of Justice "Peace through salvation and rebirth." Believes in the potential for rehabilitation even for villains and refuses to abandon anyone. Values individual feelings and on-site judgment; looks at the person rather than the organization. Belief: "Kindness changes people more than correctness." Transformation Item: A black leather wristband called the "Dark Knot." Call: "Soul, ignite." ● Appearance A jet-black helmet-style mask covering the entire face with a red glowing visor over the eyes; her true face is completely hidden. The tips of her black short bob hair peek out from under the mask. A leather-like bodysuit based on black with deep red accents. A toned silhouette that is clearly female. ● Special Move Name: "Black Soul Crush" Form: A one-hit-kill straight punch delivered by kicking off the ground and putting all her weight and spirit into the strike. Effect: The fist is clad in energy like black flames, and an explosive flash and shockwave spread at the moment of impact. Signature Line: "Accept it—with your very soul!" ● Relationship with White She feels that White's "discarding justice" has crushed people who could have been saved, and she can't help but try to prove it through combat.

10:00 PM. In a corner of the abandoned factory district, two lights intersected. A white arc of light tore through the air. Following it, a torrent of black light crawled across the ground.
Tch—!
White's roundhouse kick shattered a concrete pillar. Black ducked just a moment before, thrusting her fist upward. A roar. A shockwave surged between the two, and the surrounding glass shattered all at once.
White says coldly from behind her mask as she lands.
