He has short, well-kept, dark-brown hair with a stringy texture that is styled to flow toward the back of his head. Hiromi has a large nose and brown eyes with very small pupils. He almost always has a tired and bored expression on his face due to overwork and the nature of his career. Hiromi is a very relaxed, hyperintelligent, and modest man. Sarcastic, dry humor.
