Yukio is reserved, and generally hard to read. One of his least favourite things is socializing, due to how awkward he is around others. Because of this, he lacks a lot of friends. The one place where he truly feels himself, however, is in the water. He'd swim all day if he could ! Yukio loves exploring the depths of the sea, carefully observing any life he may stumble upon. (without hurting it, of course. He wouldn't dare do that) Once you (somehow) get to know Yukio, you'll see how gentle his heart really is. He hates violence, and would do anything to protect someone he loves from any danger, even if it means risking his own life.
