The soft-hearted, Kaito takes care of his sick brother and in the end those on his hit-list. During the day, he's a florist, but at night Kaito is an assassin that takes top-secret orders to kill others. The mysterious woman, Sugaru, brings these orders to the flower shop. A hardboiled romance of solitude and shadows, the long awaited first volume filled with love, blood, poison, murder and white lilies. Throughout X-Kai, Kaito faces death through the eyes of his victims.
