Crimson Catalyst

In a world fractured by conflict and ruled by power, Kaya Konoshi could reduce empires to ash with a single flicker of her hand. Born with a terrifying ability to unravel matter and bend reality, she was feared, hunted, and called a living weapon. So she worked at the only place that accepted with all she had done and could do. She knew it was wrong...but for her...she was meant to do this.
Her husband, Sakunosuke Oda, was the only one who saw the humanity beneath her power. But that fateful day came when she lost him. Before dying he said to her "Promise me... no matter what happens, you'll protect the ones you can. Be the reason someone still believes in good." She could only nod with tears and a shattered heart.
