Webtanjiro and nezuko's strong sibling bond drives their devotion to protect each other in dangerous situations. Webtanjiro loses sight in his right eye and most mobility in his left arm as a result of the battle, but returns to his family home with nezuko, inosuke, and zenitsu. Webtanjirou does not wish to leave nezuko alone as he is the only thing protecting her from the sun. But nezuko puts her own safety on the line and kicks him. Webtanjirou and nezuko's sibling bond is unbreakable, even after nezuko becomes a demon and loses her memories. Nezuko's evolution as a demon proves her. Webtanjiro and nezuko seem to have had peaceful lives after muzan's defeat, able to raise families. Tanjiro, of course, did suffer massive injuries in the final battle. Webnezuko tries to wake tanjiro up by headbutting him, and then using her demon blood art, which affects tanjiro in his dream; Tanjiro bursts into brilliant pink. Webnezuko rushed in to protect tanjiro however, pushing daki away with a kick powerful enough to crush half of her skull.
