Strength of a Hundred Seal

A jutsu, developed by Sakura Haruno, by and storing her chakra over a period of time, much like Tsunade's Yin Seal, in her forehead. At any time she deems it complete, she can release the chakra she stored, thus pumping the chakra back into her body. She states that this version of the Yin Seal is much stronger, as she is able to use the seal's power more liberally than the latter.

Once releasing the seal's power, the Sakura's speed and strength increase immeasurably, as she demonstrated when she completely obliterated a small army of the Ten-Tails' mini clones, along with the battlefield around them. This caused even Hashirama Senju to contemplate whether she was stronger than Tsunade's own monstrous power.
