Tsunami is tall with dark skin. His hair is colored pink and sticks up a little. He wears white goggles on his head but does not use them often, unless he is surfing. He is very energetic, optimistic and supportive of his teammates. He loves the sea, calling himself a "man of the ocean". He is also very laid-back and doesn't mind if his juniors treat him weirdly. He has uncanny athletic sense, and relates a lot of things to the ocean.
