Kazuma Senju, being the host of Amatsu-Mikaboshi, is granted the Shintō Senjutsu through combining Amatsu-Mikaboshi's chakra, with Dark Energy, gained through the use of Sage Mode.

Kazuma, after finding out about holding a piece of Amatsu-Mikaboshi inside of him, began working to draw out its chakra. It was only when he was in Sage Mode that he found he could forcibly draw out the power through the seal. Once he drawn out his body began to absorb massive amounts of Dark Energy which began to completely cover his body, forming a layer of pitch black chakra around him.

While in this technique Kazuma is able to utilize his normal techniques to a far greater extent, and his physical capabilities are increased by an immense amount. He is able to utilize many of his powerful techniques without the use of Hand Seals, and can create and manipulate Dark Matter and Dark Energy at will. He also seems to be able to completely overhaul the Flying Thunder God Technique, allowing him to jump anywhere within five-hundred meters of his center. His sensory abilities are also enhanced to the point that he is able to sense what someone will do before they do it, by reading the minute movements of their chakra. With only a piece of Amatsu-Mikaboshi's power Kazuma is limited to using the technique for around five minutes before becoming exhausted, and is then not able to mold his chakra for around twelve house after. After becoming a full Jinchuriki his limits are enhanced, being able to freely enter the form at will, and utilize Amatsu-Mikaboshi's chakra to create the Dark Matter and Energy attacks, he is also able to stay in the form for extended periods with only mild exhaustion setting in after its use.

The technique does however have its weaknesses, aside from the weaknesses mentioned above, while in the technique, Kazuma seems to be unable to access any nature transformation aside from Star Release. He also carries over his logical reasoning from Sage Mode, which put his allies in danger as he would sacrifice them as needed. It is also known that after he becomes a complete Jinchuriki, using the technique for prolonged periods opens him up to being taken over by Amatsu-Mikaboshi, therefore causing Kazuma to limit his time spent using the technique.
