Mersiry uses alot of chains which he wields under hes coat, he controls the chains perfectly with hes chakra. He also uses alot of necronic jutsus, which will be added.
Chanucha - A technique Mersiry uses to add or remove organs from/off hes body. The technique is able to compose nerves so that he should be able to use the new added organs. Itsl ike working with strings of chakra. (Yes, its the strings in hes face. Just likke thoose.) Its possible to use this on other shinobis. This is a self made jutsu of Mersiry and the idea of it is eternal power and imortality.
Hanguanora Samon - A technique Mersiry have developed to chakra heal him self, it very simple. Mersiry uses Chanucha to connect hes hand palm to a another ninja and drain the chakra needed, this jutsu is not qiet fast, so should not be used while combat or with other words, This is not a in combat-technique. It can be used at even dead body up to 20 hours after death.
Shaukoton Nesami - Also a Chanucha technique, this jutsu is used to combine brains throught Mersiry's hand palm. He easily lays a hand on the the target's head and combines the nerves to hes head. This technique is very very slow cause of the many nerve combines needed. This jutsu can also be used at dead bodies up to 20 hours after death.
Soutonatre Hakto - Merisy pulses necronic chakra/dark chakra throught one of hes chains. He usual then slaps the chain claw into the goround realising the power. The power then takes form as a ball running under the ground at the target, the power ball can go throught many materiels, but not air. It needs to hit something. When it hits it explodes.
He can also just fire the impulse into something, like if he have a claw in an enemy he can release into this. He can also do it to walls and such.
Hansetrio Doubbla - Mersiry concentrates chakra one place and reforms a new organ out of fat and nerves made by Chanucha. This could be like everything, an arm, a leg, a head, a wing. This jutsu cannot be used for longer periods, and Mersiry only uses it in mergency cause it leaves a big leak of energial vertamins in hes body.
