Knuckle's Maximum Break (ナックルの極限ブレイク, Nakkuru no Makishimamu Bureiku) is the circumstance in which the First Generation Vongola Guardian of the Sun Ring, Knuckle, gave himself a three minutes time limit and saved the Vongola by boxing. Through future Vongola technology, the 10th Generation Sun Guardian, Ryohei Sasagawa, can use Cambio Forma to re-enact this circumstance. During Cambio Forma, Ryohei's body is shot by the Sun Enhancement Shot. His Vongola Box Weapon, Kangaryuu V.V.B., transforms into a set of gloves and a helmet.

Ryohei's body glows with the Sun Flames' color. His body structure and, correspondingly, abilities are enhanced. As such, he is capable of performing extraordinary feats of speed and strength. The gloves and helmet are enhanced with Sun Flames and have the Roman Numeral "I" on the gloves and the Vongola Sun Emblem on the helmet to symbolize the connection to the First Generation Sun Guardian, Knuckle.

However, few humans have the body structure to withstand the strain of the flames of the enhancement shot, as they would collapse under the overwhelming pressure; Ryohei can withstand this pressure for only three minutes. Once the three minutes are up, the white gear of the Cambio Forma turns black and the glow around Ryohei's body diminishes. Ryohei also experiences the side effects of the pressure then.


  • Maximum Combination: A high speed range of punches using both arms. While it is not as strong as other attacks, it is almost impossible to dodge.
  • Maximum Cannon: Resembles the original Maximum Cannon but the attack now also produces Flames that can strike from a distance.
  • Maximum Ingram: Resembles the original Maximum Ingram but is greatly improved in both speed and power.
