Blooming Corpse Flower

Using the Shikotsumyaku Izuna is able to create small pale senbon like weapons to use against his foes. This is entirely deceiving though, the bone weapons having a secondary purpose. Once the needle has entered into flesh the tip will flower out and solidify, making it extremely hard to remove without medical assistance if the victim does not wish to further injure themselves. With the razor petals of the bloom grinding on their innards it is enough to slow down even the most hardened shinobi, as is the intent of this jutsu.
