Yomi Isayama

Yomi Isayama is the deuteragonist (and eventual main antagonist) of Ga-Rei Zero and a major antagonist (and later the tritagonist) in Ga-Rei. The close friend and sister-figure of Kagura Tsuchimiya, Yomi is an orphan adopted by the Isayama family and raised as one of its own, groomed to be the clan's heir from a young age and bestowed with its family sword, Shishio. Yomi tragically fell to darkness after being corrupted by the power of the Bane Stone (sesshōseki), and her descent into evil is the main focus of the anime series. Yomi is an attractive girl of medium height, possessing purple eyes and jet black hair that is as long as her waist and falls down over her forehead in a trimmed fringe. In the anime, just like Kagura, she is shown wearing her black and white school uniform most of the time, even donning it during her Vanquisher duties. Towards the end of her life her uncut Bane Stone could often be seen glowing in the middle of her forehead, signifying moments at which Yomi was in control of her own actions. After her death and subsequent resurrection as a spirit, Yomi's appearance became far more demonic in nature, with serpentine eyes, the Bane Stone visible on her forehead and sharpened teeth. She no longer wore her school uniform in this state, instead almost always wearing a kimono and carrying a parasol on her.
