The Arcobaleno are the holders of the Arcobaleno Pacifiers, a part of the Tri-ni-set. Before being inflicted with their Arcobaleno curse, they were known as the World's Strongest "I Prescelti Sette", the World's Strongest Selective Seven. There is an eighth named Brumuda von Vitchenstien who shares their curse, but not much is known of him.
