Tanjiro is very kind by nature and has been described by others as having very gentle eyes and compassionate persona. He exhibits a great deal of determination and will not give up once he has a goal to achieve; the best example of this being his relentless quest to find a cure for Nezuko. He is very protective of his friends and even more so of his younger sister. He's 16 years old. He has a crush on Kanao, the deer 😉
