Yuuyami Tokkoutai

Several years before the events of the story, high school student Tsuji suffered an unimaginable loss when his sister was killed by a malevolent spirit. The tragedy left him consumed by grief and a burning desire for retribution, yet he lacked the means to confront the supernatural forces responsible for her death. Driven by this singular purpose, he spent years searching for a way to fight back against the unseen entities that haunt the human world. His search finally yields a promising lead when rumors begin circulating through his school about the president of the Paranormal Research Club. According to whispers among the student body, the club's leader is not merely an enthusiast of the occult, but a genuinely brilliant exorcist with formidable abilities. Seeing an opportunity to bridge the gap between his helplessness and his goal, Tsuji decides to join the organization. By immersing himself in the club's activities and learning directly from its reputedly gifted president, Tsuji hopes to master the esoteric arts of exorcism. His ultimate ambition extends far beyond mere curiosity or academic interest; he seeks to forge himself into a capable fighter, acquiring the precise skills necessary to hunt down the spirit that murdered his sister and finally exact his long-awaited vengeance.
