After Anko recovers, she reveals the truth about her past and this chain of islands. She tells her team that several years ago, Orochimaru used this place as a base to conduct many of his horrific experiments. He was responsible for the people mysteriously disappearing; kidnapping them and using them as lab rats. Isaribi was one of them. These actions also started the legend of people being captured by spirits. Determined to make Orochimaru pay, Naruto insisted on destroying the hidden lab.
