The Demon Lovers

okay soooo this is an AU where Genya and Tanjiro are demons, Tanjiro is a demon like how Nezuko did and Genya is a demon for until he finds a lover due to Sanemi keeps making him eat demons until Sanemi says he finds a lover, but now hides in the dark because anyone he tries to date, would run or cry calling him a monster

What if Giyuu adopted Tanjiro and Nezuko and trained them water breathing, but what if Tanjiro had all:
Sun -earrings
Moon- ring
Water
Flower
Thunder
and Flame, how would most of the Harisha and KamadoSquad react to this.
