Motoi

guides Naruto Uzumaki and Yamato through the island, where Killer Bee trained to control the Eight-Tailed Giant Ox.

Fourth Shinobi World War arc
Motoi greeted Naruto, Killer Bee and the rest of the Kumo and Konoha-nin as they arrived on the island, and took them to their lodgings. After failing to get Bee to train him, Naruto asked Motoi how he could convince Bee to do so. Motoi reprimanded Naruto for speaking badly about Bee, and asked him if Bee greeted him. After Naruto confirmed it, he replied that Bee may have had his reasons for refusing to take Naruto under his tutelage, and then guided Naruto and Yamato to the "Falls of Truth," the place where Bee trained to control his tailed beast. He instructed Naruto to sit in a platform and close his eyes, which caused an evil version of Naruto to appear. After Naruto awakens, Motoi tells them that Bee was also hated by the villagers when he was younger. Naruto asks him to ask Bee how he controlled his Biju for him, but he refuses, saying that he tried to kill Bee once. Then, he begins to talk about an incident that happened 30 years ago. He tried to kill BEEE!!!!
