Sakamata (サカマタ) is an orca and ranked second of the Ushimitsudoki Aquarium and acts as Isana's right-hand, often taking direct orders from him and able to give orders to the other fish and mammals at the aquarium. He appears in the show by the pool with Kaizou. Sakamata is a rare type of orca whale called a "transient" which means that he is a rogue amongst orcas and does not need to hunt in small groups like most of his kind, which is something he relishes in. He is arrogant and menacing.
