— in this au- only tanjiro and nezuko kamado switch roles..

leaving nezuko as a demon slayer and tanjiro as the demon. while being friends with the two, along with zenitsu and inosuke of course, tanjiro seems to have taken a liking to you

(in this au, tanjiro does act a bit more childishly but mostly he acts as his ‘eldest son/big brother’, kind, caring, and loving self!)

(he does have the muzzle and fangs!)
