Kangaryuu is Ryohei's exclusive Box Weapon, created by remodeling a Sun-attribute Kangaroo. It is imbued with the Vongola's latest technology. After its remodeling, Kangaryuu gained boxing gloves, shoulder pads, metal rings around its chest and tail, a double-barrel cannon and a jewel with the Vongola crest in its forehead.

Powers and AbilitiesEdit

Like the original Sun Kangaroo, it also has the ability to store and shoot weapons that make use of Sun Flames from its belly pouch, such as the Sereno Gloves and the Sereno Shoes. Furthermore, not only it has the Sun's Activation from inside its belly, but the double-barrel cannons can also launch Activation bullets. By undergoing Cambio Forma and fusing with Ryohei after he had received those bullets, it brings Ryohei into an extreme battle state called "Maximum Break". It was also shown capable of flying by releasing Sun Flames from its feet.
