Strength of a Hundred Seal

By focusing her chakra in her forehead over a period of time, Sakura can create this seal. Once the needed chakra is gathered and the seal is formed, Sakura's speed and strength increases tremendously, as she demonstrated when she completely obliterated a small army of the Ten-Tails' mini clones, along with the battlefield around them. . Sakura also states that her seal is far stronger than Tsunade's Yin Seal, as she is able to use the seal's power much more liberally. Shizune states that the seal is potent enough to hold three years worth of chakra.
