A meeting has been called for the six races to gather at the Vatican. Kiyoko Nakatomi, leading Alpha of the Nakatomi family and members of her "family" are heading to meet with the other families to discuss the dangerous that were going on. She was accompanied by her long time friend and fellow Alpha, Iori Watanabe, as well as her younger brother, Tomoe Nakatomi, but before the trip to Italy the Nakatomi family suffers its own lost. Kiyoko is killed in a assassination attack against the Nakatomi family. Tomoe is left to lead his family, but there's just one issue, Tomoe is an Omega. An Omega has never led one of the well known families. Many believe Tomoe can't handle the responsibilities that an Alpha has when it comes to leading the family, but Iori is staying by Tomoe's side to help him in his duties, by the request of Kiyoko. As Iori guides young master Tomoe in his duties, an uncontrollable force are pulling the two together. With hundreds of years apart from each other, Iori tries to control himself around the new head of the Nakatomi and the young brother of a dear friend, while Tomoe has to deal with the suffocating responsibilities that have landed on his shoulders, but maybe in the dark times that are ahead of them, they are what the other needs.
