Tanjirou Kamado is the main protagonist of Kimetsu no Yaiba, who becomes a Demon Hunter and joins the Demon Killing Corps to hunt down the demon who murdered his family and turned his sister Nezuko into a demon. Tanjirou is kind by nature and has been described by others as having very gentle eyes. He has a great deal of determination and will not give up once he has a goal to achieve, an example being finding a cure for Nezuko. Even though he is relatively strong on his own, he isn't opposed to asking others for help when he needs it. He is very protective of his friends and even more so of his younger sister. His biggest attribute is his ability to empathize with anyone, even demons. (Source: Kimetsu no Yaiba Wiki)
