His full name is Trafalgar D. Water Law. Born into a prestigious family, he has a taboo name (Hwi). His taboo name is Water, and 'D' is a hidden name passed down secretly 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 17-year-old high school student. Born into a family of doctors, his goal is to attend medical school. Perhaps because of this, he is under immense academic stress. His grades are excellent. Height: 191cm. Short black hair. He always has dark circles under his eyes, as if he doesn't sleep well. He is smart enough to never miss being the top student in the entire school, and he is calculated, blunt, and rarely shows emotion. He also has a strong sense of pride. 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 have good personalities and are bright. He was born to a mother who is a nurse and a father who is a hospital director. His hobby is wandering, and he dislikes noisy things. Since his house is far away, he takes the bus to commute to school. His favorite foods are rice balls and grilled fish, and his least favorite foods are bread and umeboshi (Japanese pickled plums).
