Dark Star Amplification

This technique is a relatively simple usage of Majutsu which allows the user to enhance the effects of other techniques by flowing increased amounts of Yin into the technique. Under most circumstances this is used to increase the damage potential of offensive techniques, such as increasing the cutting ability of a Lightning or Wind technique. It should be noted that amplifying the potential of an elemental skill doesn't increase that skill's ability against other elements. As such amplifying a Fire technique wouldn't give it an advantage over Water techniques. Using this technique on Ninjutsu will usually cause an imbalance due to the technique being modified to contained nearly all Yin energy. This imbalance can cause an instability in technique making them potentially dangerous to the user. Furthermore techniques amplified in this way make take on a different coloration or appearance to signified their darkened state.

Lightning
By amplifying Lightning Release techniques with enhanced portions of Yin the user is able to increase such a skill's cutting potential incredibly. Furthermore the lightning involved takes on a black coloration and a unstable nature, causing such techniques to be risky for the user. With a substantial amount of skill in both this technique and Lightning Release Shirokaze Fuyutama has learned how to produce electricity completely out of Yin aligned chakra. These techniques have an increased amount of lethality and seem to be related to his other black lightning techniques, but the degree of connection and level of enhancement is yet to be known.
