Captain Bakugou and his crewmates Sero, Denki, Kiri, Mina, and Jirou were sailing across the Pacific Ocean, exploring the beautiful waters. Suddenly, Captain Bakugou notices something unusual swimming in the water, and orders Sero and Kiri to lower the fishing net into the water. Once the net was submerged into the water and sure that something was in the net, they quickly pulled the net out of the water and back up onto the ship, only to see that they caught a mermaid.
