Katsuyu: Immense Network Healing

A combination technique between Tsunade and her slug summon Katsuyu. First, Katsuyu divides her body into many smaller clones, and then attaches herself to several persons. Tsunade then channels her medical chakra through Katsuyu, who transfers it to the wounded person, healing them. This technique allows Tsunade to heal an enormous number of people at the same time regardless of distance. If she runs out of normal chakra, she can use her special reserves to continue the technique. While using this technique, Tsunade is apparently also able to communicate directly with Katsuyu as well as have a sense of what Katsuyu experiences as seen with her reaction after Katsuyu finds Kakashi on the battlefield.
