Ruggito di Cieli is a Flame-based attack in the form of a roar. It can petrify the enemy or their Box Weapon on the battlefield through the Harmony powers of the Sky Flame. The one used by Bester is somewhat different due to its two Flames, Sky and Storm. After the Sky Flame's Harmony characteristic is done petrifying the opponent on the battlefield, their body will be destroyed by the Storm Flame's Disintegration characteristic.
