Yin Seal: Release

Yin Seal: Release is a powerful sealing technique developed by Tsunade. Over a period of time, Tsunade will focus and build up chakra in the seal mark on her forehead. The release command will disperse the seal and allow the stored chakra to pump back into her body. With this extra-suplemment of chakra, she can either perform Creation Rebirth on herself, or transfer it into others through Katsuyu.
