Love this story, though some things about it could have been thought through more. For example the Rasengan combining with the claws the way it's described doesn't make sense. A ball of spinning chakra chakra held in the palm of the hand wouldn't be able to just transition to the back of that same hand. Even if they are going movie style where they come out from between the fingers, the hand would still need to be a fist for them to extend and not open to hold the energy ball.
