Naidō Banshō

"A technique that can consistently be used. Much like today's known "spam", Sigma will continuously launch until you, the opponent is hit. Evasion is possible, yet it isn't. Flawless, no. God-like no. Sigma-style, yes."

- Naidō about the technique

 is a technique granted to Sigma's Rinnegan, with the extensive help of the Yin-Yang Release, intact, Sigma has recently made it one of his primary arsenals. Naidō, has noted that his Naidō Arts could have possibly generated from this technique.

Overview
This technique gains origin from Sigma's sword, the Lame. His concept was simply, combine Onmyōdō with kenjutsu. Easy as it sounded, it wasn't done, in-fact it took Sigma over two months to future out it's missing component, which was later to be the Rinnegan. He noticed, his yin component over threw the yang, and its off balance was the reason why he couldn't launch the technique how he wanted.

Usage
Sigma channels and  towards the tip of his blade. Once done, he must balance the two, at a ratio of 3:5, making the yang more dominant. When he swings his Lame, to unleash the attack, he must quickly swap the two, at a ratio reading of 5:3. When the technique makes contact with the target, their internal organs begin to take damage first, which can leave the foe like jelly. The destruction then begins to move towards his/her external means. At this point, the foe's body will begin to rip, taking its flesh with it.

With help from the beasts' chakra, Sigma can extensively create it's. This is only possible when Sigma uses the technique with his hand...
