Kira Fujikawa has always felt different. She’s constantly bullied by the popular girls in school. Her family ignores her. And then there’s her secret ability to see yokai, the ghosts and demons that haunt the streets of Kyoto where she lives. The only place she’s ever felt at home is at her grandfather’s shrine—until it is invaded by violent demons and he’s killed. Kira narrowly escapes but soon learns that the Shuten-doji, the demon king, has risen to hunt down the shards of the Sword of Kusanagi—an ancient relic that, if captured and put back together, will bring the world to a catastrophic end at the next blood moon. To have a chance at fighting the Shuten-doji, Kira must find seven powerful demons who are willing to help take him down. With insurmountable war drawing nearer by the day, Kira realizes there’s a lot she doesn’t know—about the yokai world, her family, and, most alarmingly, herself. With the fate of Japan on her shoulders, could Kira actually be the one to spare humankind from eternal darkness?
