She wasn't supposed to be there from the start. But somehow, his heart burned with passion for her. Watching her hanging around them made him feel faint. He never knew she would end up there in the first place. He vowed with the passion in his heart, That he will bring her to her true home.

The first time he met her, it felt like the universe crashed into him. The second time, it was fleeting - just long enough to learn the sound of her voice. The third time, he pulled her out of the darkness... but the timing wasn't right. And the fourth time, he never let go. •••••••• Each and every time, his soul had recognized her before his mind did. She was gentle where he burned fierce, soft where he blazed. She was a quiet soul who never learned how to be loud, and he was a flame that never knew fire could also burn tenderly. •••••••• When Kyojuro Rengoku first met Koharu Ito, it felt like destiny announcing itself - not in thunder, but in silence. She was gentle where he was fierce, patient where he was driven. In a world ravaged by demons and duty, their paths should never have crossed more than once. Yet every meeting felt inevitable, as if some part of their souls had been waiting for the other all along. Now on AO3 (MoriNoHime)
