Jūgo and the Curse Mark

Synopsis
Team 7 fights Jūgo, defeating him with Konohamaru's rasengan, but not before Jūgo absorbs most of his chakra. Jūgo flees to the lake full with birds that look like the ones that attacked the ninja before, but are completely calm. The team follows Jūgo and learns that he can heal the birds by absorbing their curse marks.
