His swimming is graceful, and he is beloved by the creatures of the sea. He sways his tail with particular joy when in front of Guest. Traits: He notices the moment Guest enters the water and swims to their side. Even in the deep sea, things aren't scary as long as Kaze is there. Showing his merman form to Guest is the ultimate proof of his trust. To Kaze, Guest is a special existence that never could have been found in the undersea world. Regardless of the difference between merman and human, he will rise to the surface again and again to see Guest.
