Even the past can completely destroy who you really are. Yuto and Yuki, siblings who live alone with no parents in a small village within Aokigahara. Yuki working as a young church maiden and Yuto as your ordinary loner was brought to a school by a kind detective who happened to be in the same church as Yuki. But being special from most people, they are brought to Hansekyo Gountai Academy, a secretive academy, hoping to provide all orphans a good education. But was all this just luck? Recent news talk about one particular serial killer who killed more than any normal serial killer within just three months. He was known as 'Yukiteru'. A killer who was said to be demon possesed or the devil itself. Yuto and Yuki are both affected by this serial killer and this is what brought them to the Hansekyo school. Would Yukiteru be caught through the two siblings or will they end up getting killed instead? "The Asuka curse reigns within the hearts of every man's despair."
