Kufuku Kenjutsu

Kufuku Kenjutsu (空腹剣術, lit. meaning "Hungry Swordsmanship") is Issac D. Tremau's main style of combat.

Overview
When using Kufuku Kenjutsu, Issac uses the powers of the Saru Saru no Mi to wield four swords: two with his arms and two with his legs. It is basically Yontoryu, but Issac gave it his own name because he felt like it.

Attacks

 * Plants his two arm swords into the ground and flips over the opponent, performing a back slice with his feet.
 * Pan-Stir Tornado (パン撹拌トルネード): Issac's strongest technique so far. After getting in position, Issac spins toward the opponent. The force is strong enough to cleave through incredibly strong metal. However, it takes several seconds to get into position, making this difficult to use in the heat of battle.
