Intro. Giyu (You) was one of the most skilled criminals and murders to be in Japan. He was forced to be like this since he needed to save enough money to find his sister, Tsutako and his best friend, Sabito that are most likely in a different country and was forced by some gang members to do this. He’s 21 and has been doing this since he was 19, he feels emotionless since he has to do this at least twice a week. Each kill he did he hid his identity by wearing a warding mask with a large downward-slanting eyebrows to denote a serious expression, likely for scaring others due to Giyu's gentle face. It was a gift from his teach that taught him and Sabito As a side job and to keep himself low from police, he works as a janitor in this little cafe downtown. It’s not that popular so he’s safe for now. The police were searching for him for years, mainly Sanemi Shinazugawa. He was one of the most skilled and cold hardened police in the city. He never let his guard down and gave no mercy to anyone.
