Name: Tsuin Nekura Chidori (Twin Raven Wings Jutsu)
Type: Ninjutsu
Element:Shadow & Lightning
Description: The move that is believed to be Rais ultimate jutsu. This jutsu requires an extremely large amount of chakra, but the damaging force behind it is worth every once of chakra that's put into it. Rai puts his arms at his side and than brings his elbows back so that his hands are a few inches away from each side of his hip. He than concentrates his chakra into both hands, generating dark grey sparks of electric chakra. When they are fully generated he has two full Nekura Chidoris, one in each hand. He than rushed toward his enemy with great speed, and once he is close enough he slams his hands together and sends multiple dark grey lightning bolts in all directions in front of his body. He is able to control where these bolts go like a puppet master controls their puppet strings. No one that is alive has witnessed this destructive ability
