Senjuro is originally seen to be very sad and rattled by his brother's death and his father's verbal abuse, but, after spending some time talking to Tanjiro Kamado, his true personality as a kind, caring individual who can usually see the best in a situation or person shines through. He has hope for his future, and even though he knows that by not becoming a Demon Slayer he has broken his family's ancient tradition, he knows that his older brother, Kyojuro, would forgive him nonetheless.
