Dusk Release: Deterioration of Darkness is unique ninjutsu created by Sōma Chinoike after witnessing a Nubatama member use dark parasite on a enemy in battle, with such knowledge and extensive studying of her clan's power of Dusk Release and Shadow Chakra in their bloodline but unsuccessful in creating a technique with greater power. Two long years of training and wandering the clan's ruined home she ended finding a wounded and blind elderly man who then exposed Sōma to Dark Matter, surviving the ordeal she used this power to fused with her shadow chakra to create a technique that can corrupt and take the will of any living being.
Usage[]
This technique is unique but strongly forbidden for any clan member or shinobi in any village to use for their own benefits seeing that it bring harm to others and themselves. Utilizing Dusk chakra with shadow chakra after weaving through the proper hand seals will cause her eyes to glow a stormcloud color in her pupils like a flickering flame, once the technique is active Sōma introduces this power through various methods from ninja tools such as Kunai, Shuriken's and Swords to Taijutsu, once she is able to cut or touch an living being her chakra infested with dark matter will begin to infect their body on a cellular level that even their chakra network is infected. The target wouldn't notice this for some time as they fight or flee until they try to mold chakra only to convulsed, falling onto the ground in pain unable to function until she use her chakra that's infesting their body to corrupt and bend the target into her loyal husk-like entity with similar glowing eyes like Sōma. This process works faster on the weak individuals with no will power and weak minds but it's instant with animals.
Recoil/Consequences[]
Such great power comes with a price depending on its nature, like the Eighth Gate of Death your life, Earth Grudge Fear allows the user to live a very long life but requires the extraction of four additional hearts turning the user into a grotesque being with black threads, and Izanami that gives you the power to trap an opponent in a loop that'll only end once they acknowledge their mistake but at the cost of your eye to be blind forever. This technique grants the power to take a potential victim and turn them into a supernatural soldier but at a price of their sanity and possibility of them succumbing to parasitic nature of Dark Matter corrupting them as well if continue use of this technique.
Bypass[]
There is a way to bypass this and survive without consequences taking ahold of them down the road, however, this is considered taboo in the most sinister way possible. According to Sōma who began showing symptoms used vessels to contain her dark matter to slow down the progress but eventually the other vessels died forcing her absorb the dark matter, a temporary solution to her problem for her problem until she began having craving for human flesh not just typical human flesh but a specific kind according to her when she devoured several powerful shinobi's until she sunk her teeth into a Uzumaki and Nubatama couple; both containing the powerful Life Force and genetics assimilating their very essence that'll not only stop the corruption process but will evolve the user once they are rendered unconscious taking about four to seven weeks until their body have finally adjusted.
