My father truly did not tell me all that came with my bloodline o_o
That is nothing my friend. as a kaguya there are times when you will need to force dragons from only the ribcage in your body. Manipulate the osteo-cells that compose those bones of yours and mass replicate them. many millions and billions times over to create whatever size bone you need. U_U
Now for now, just force that chakra around the ulna and have it slide up up through the wrist into the palm.
it'a laughable that you would consider me your rank, but that's the youth these days no respect for the elders... *smh*
Looking good though. Now moving on i want you to visualize a sword. hilt and blade. i then want you to pull that sword in your minds eyes out of your shoulder blade.
* I quickly gather a large amount of chakra and send it towards the area around my ulna bone. I then infuse some of my chakra with my ulna bone while supplying the area around the bone with enough chakra to replace it's former amount. After Infusing the chakra with my bone I quickly force my chakra forward and therefore force my ulna bone through my wrist, leaving it placed in my palm. I finish by infusing my chakra with the skin where the bone popped out and closing the gap left by the bone, allowing the regeneration of my skin*
Ready when you are sensei
