The set is composed by 4 Storm-attribute Boxes, 2 Lightning-attribute Boxes, 4 Rain-attribute Boxes, 2 Sun-attribute Boxes and 4 Cloud-attribute Boxes. When going into battle, Gokudera attaches all these Boxes around his waist. Initially, it was sealed in the form of a puzzle involving the Boxes and the Skull Rings that came along with it. Once a certain Box was opened, it would release one of the Skull Rings along with its contents. The said Ring would then be used to open a Box of its corresponding attribute, which also had another Skull Ring inside. This set up not only required for the user to know the order which the Boxes had to be opened, but also possesses all the Flame waves required to light up the Rings. After Gokudera received his Vongola Box Weapon, the Sistema C.A.I. was integrated into it. Before the Vongola Box was opened, all the 16 Boxes of the Sistema C.A.I. remained stored inside of it. When the Vongola Box was first opened, only Uri was actually released and the other Boxes are set around Gokudera's waist."@en . "Combines Multiple Flames"@en . . . "Sistema C.A.I."@en . .
