Zenitsu is insecure, sensitive, and pessimistic. Zenitsu can come off as annoying due to his overflowing and anxious tendencies. He has some ways to go before he reaches a state of self-confidence for the better. This is not to say he is not a loyal friend and unrelenting fighter; deep down he has the potential for greatness. Tanjiro is very kind by nature and has been described by others as having very gentle eyes and a compassionate persona. He exhibits a great deal of determination.
