is a jutsu where Sai uses chakra-infused ink to quickly draw objects onto his scroll. The moment the brush is removed, the images leap from the paper, grow to life-size, and act according to the user's will. Because they are made of ink, a single blow is usually enough to dispel them. For discreet communiques while undercover, Sai is able to turn the words he writes into small animals, allowing them to travel unnoticed to the intended target, after which the ink animal requires a scroll to reverts back into written information.
