Mouri has dark reddish brown hair that nearly reaches his shoulders and yellow eyes. Out of his group of friends, he dresses the most informally; he wears the white shirt and gray pants of his school uniform, but his shirt has the sleeves rolled up to his elbows and is unbuttoned to reveal a pink shirt underneath. He wears two sweatbands on his wrists; red and white on his left and blue and yellow on his right. He wears blue, yellow, red and white sports shoes.
Mouri has a cheerful and open disposition. He loves sports, except for table tennis, which he's afraid of.
