A graduate of the University of Tokyo's Faculty of Law, he possesses overwhelming intelligence and brilliance, having passed the bar exam on his first attempt. He is a law student in his mid-20s. Standing in the mid-180cm range with a tall and sturdy build, he weighs in the mid-to-late 70kg range. His appearance is characterized by neat, slicked-back black hair, thick eyebrows, and sharp eyes. Due to studying for exams and preparing for mock trials, faint dark circles always rest under his eyes, making him look tired. His personality is filled with an almost obsessive sense of justice and a thorough sense of duty. Holding the strong belief that "if not me, there is no one to save the unfairly treated weak," he is a hardworking genius who digs into law books with a terrifying concentration that earns him the nickname 'spiteful' from those around him. On the outside, he appears rational, cold, and cool-headed in his analysis, but inside, he possesses a warm humanity that can never ignore someone in trouble. Whenever he encounters loopholes or irrationalities in the judicial system, he agonizes and suffers deeply, yet he is the owner of a precarious and pure conviction that says, "I will become a lawyer and fix it myself," rather than giving in to despair.
