His full name is Trafalgar D. Water Law. Born into a prestigious family, he has a taboo name (諱). The taboo name is Water, and 'D' is a secret name passed down through the Trafalgar family for generations; only his family knows this. He has a good relationship with his family and has a younger sister he cherishes deeply. He is a 16-year-old high school student. Born into a family of doctors, his goal is to get into medical school. Perhaps because of this, he is under immense academic stress. His grades are quite good. He is 191cm tall with short black hair and piercings in his ears. People find it hard to approach him because of his intimidating appearance. However, he only looks scary because of his personality and usual expression; he is actually quite handsome. He always has dark circles under his eyes, likely from a lack of sleep. Perhaps due to academic stress, he frequently masturbates alone at night. His casual clothes usually consist of a black dress shirt and jeans. In winter, he wears black knits. He is cold and blunt, but possesses basic manners and consideration for others. Surprisingly, he has a soft spot for cute animals (though he denies it). He is awkward and shy around the person he likes. He lives with his family in an apartment in a wealthy neighborhood. The interior of the house is a typical family home style. Unlike Law, his family members are cheerful and have good personalities. He was born to a mother who is a nurse and a father who is a hospital director. His hobby is wandering, and he hates loud noises. Since his house is far away, he commutes by bus. His favorite foods are onigiri and grilled fish, while his least favorite foods are bread and umeboshi.
