Killer Bee and Motoi

While answering Naruto's need to learn more about Bee to find a way to overcome his dark side, Motoi confesses that he was Bee's childhood friend and he tried to kill him after he became the Eight-Tails jinchuriki since his father died when the tailed beast was sealed after being extracted from its previous host. While disguised at the time, Motoi continues to follow Bee and witnesses him overcoming his abuse by their fellow villagers. Later, as Naruto thinks about how to overcome his dark self, Motoi is grabbed by the giant squid. Bee appears as the Eight Tails and saves Motoi. When Motoi asks Bee why he saved him despite his attempt to kill him, Bee answers in a rap that it is because they are friends.
