Katsuyu: Immense Network Healing

A combination technique between Tsunade or her disciple, Sakura, and their slug summon Katsuyu, where first, Katsuyu divides its body into several small clones, and then each attaches itself to a person/persons. The user then channels her medical chakra through Katsuyu, who in turn transfers it to the wounded person, healing them. This technique allows the user to heal an enormous amount of people simultaneously regardless of distance. Additionally, if Tsunade runs out of normal chakra, she can use her special reserves to continue the technique. While using this technique, Tsunade is apparently linked with Katsuyu, as she is able to communicate directly with the slug and also has a sense of what Katsuyu experiences; this was seen when she reacted to Katsuyu finding Kakashi Hatake on the battlefield, and later when she told Chōji Akimichi that his father was still alive.
