Icolo (イコロ) is a guild made up of the three Arena Emperors. It was originally founded by Antares as a place reserved for the most powerful Arena fighters. However Antares grew disillusioned when he discovered that the other Emperors valued their titles and the status it gave them more than their comrades or improving their skills. Leaving the Guild he gave his title of Guildmaster over to Taihaku, who still rules over the guild to this day.
