The user circulates their chakra through their vascular system, before forcing the suffused blood to rise to the surface and pour out of their pores, forming it into a circle of senbons around them. With a hand wave they can then send the senbons outwards in a single wave of piercing rain at their target. These blood senbons are slightly stronger then regular metal senbons thrown by a ninja, so they deal slightly more piercing damage then a standard senbon.
