Lampo's Shield (ランポウの盾, Ranpou no Shiirudo) is a shield which was used by the First Guardian of the Lightning Vongola Ring, Lampo. Through future Vongola technology, the 10th Generation Guardian, Lambo, can transform his Vongola Box Weapon, Gyuudon, into a model of this shield. This weapon is equipped with a horned shield and has the Roman Numeral I on the front to symbolize the connection to the 1st Generation. The shield is also equipped with two horns like Lambo's horns that are encircled by rings, and also forms a helmet with a Lightning Crest in the middle.
