After completing his "True Star Release" Kazuma is able to infuse Yin-Yang Release into his techniques, by infusing it into this technique he can create actual swords made of energy instead of the energy forming around his hand. The blades cutting power is also increased allowing it to cut straight through ninjutsu by nullifying it. Kazuma is able to create a number of these blades and extend them as he was able to do before. Seiken3.png|The new blades. Seiken2.png|Extension.
