In a port city in the Kantou region, there lives Tandouji Aruma who lives a lonely and solitary life. One day, he is approached by Aiba Ruri who asks for his help, for the power of the Sacred Seven which resides within Aruma. However, Aruma turns her away, since in the past, he had hurt people with that power, so he had forsworn using it. But when the peaceful city is attacked by a monster, Aruma reluctantly decides to use the Sacred Seven. However, his powers go berserk and the situation becomes even more dire. At that moment, Ruri comes to his aid. ~ translated and adapted from official site by Cranston
