Heal Bite

Karin can heal other's wounds by having them bite into her skin and suck out her chakra. Despite healing the person's wounds, it does not fully restore the person's chakra. In addition to rapidly depleting her chakra reserves, Karin is left with a permanent bite mark every time she uses it. Due to this depletion of chakra, it is dangerous for her to use this ability more than once a day. She also appears to become aroused when she is bitten, but this could merely be the fact that it was Sasuke who was biting her.
