There is a murder aboard the ship carrying the people rescued from Dotou Island, and Kyoho is the primary suspect based on the evidence. Despite his claims of innocence, there is no proof to back him up. Despite that, Kagura chooses to believe Kyoho. He places Boruto and Iwabe in charge of watching Kyoho while everyone else splits up into teams to search for any clues that may point to another culprit.
