This is one of the ultimate fighting techniques and ninjutsu of the Sagii family. This technique requires immense training and chakra manipulation. Kenno Sagii's version pales in comparison to his grandfather Fushimo Sagii's, but it still makes him a formidable opponent in many aspects.

After forming the needed hand signals, the user manipulates the tenketsu in their body and uses them for form two or more arms made of chakra. While doing that, the user summons an amount of weapons and forms a special seal to keep the chakra arms sustained while the arms manipulates the weapons. When done perfectly, the arms will act as if they are the user's own, attacking and defending according to their will. If the user is trained in many weapon styles, or even just one, they can become a destructive force with both offensive and defensive advantage. Depending on the user's skill, more than two arms can be created. Kenno can make up to eight and Fushimo can create up to fourteen.

However, this jutsu is extremely chakra taxing, forcing the user to only use it about once a day. Also, the strain of using multiple weapons at once could disorient the user, so immense training has to be put into his technique. Plus, the user cannot cease the last seal during the jutsu, or the arms will vanish. However, they can move during combat without disrupting the technique. They must continue to give chakra to the arms as well as manipulate them. Also, this technique is only used to create the arms to wield weapons and cannot deflect strikes alone, so weapons are required to have a defensive edge. Kenno is able to charge lightning chakra into this technique to increase its effectiveness.
