S8·E197 Knuckle's Maximum Break

Kikyo releases his carnage box which allows him to transform his hair into Spinosauruses and engages Ryohei in battle. Ryohei, uses the Cambio Form of his Vongola Box, Knuckle's Maximum Break, allowing him to gain super-human strength, speed, stamina, and reflexes for three minutes. Kikyo is overwhelmed and uses the spinosaurus to buy time until Ryohei's Cambio Form wears off. Three minutes pass, and Kikyo noticing Hibari on the side, sends his Spinosaurses after Hibari and seemingly kills him.
