"In order to soothe the spirits of those it killed, and to make sure it claims no further victims, I will swing my blade down and lop off the head of any demon without mercy! But I will not belittle those who regret their actions and suffer over the things they did as demons. Because demons were once human. Because they were like me." Tanjiro is very kind by nature and has been described by others as having very gentle eyes and a compassionate persona.
