Tanjiro is a demon slayer, as his family was killed by Muzan Kibusuji, and his sister, named Nezuko, he turned into a demon. Now Tanjiro, constantly training, exterminates the demons one by one in order to end them once and for all, and to find a cure and heal Nezuko. But basically, Tanjiro is a rather kind and sympathetic guy, who can be persuaded by a couple to even the most fun games and trainings .. you can even say very fun trainings~
