The stage is a certain port city within the Kantou region. There resides Tandouji Alma, 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 Alma. However, Alma turns her away. In the past, Alma had hurt people with that power. Since that moment, he had forsworn it. But when the peaceful city is attacked by a monster, Alma 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 by inserting a sacred stone - the jewel from her necklace - into Alma which transforms him to his true form. (from Wiki)
