Demon Slayer: I, the Son of the Sun, Kneel Down and Call Me Daddy.

Kazuki, who was reincarnated into the Demon Slayer World, became the son of the Demon Slayer Lord, Ubuyashiki Yōya, and gained the power of the sun. Sun Breathing Technique? Sorry, I am directly using the power of the sun, and I can't bear it no matter how miserable it is. Kazuki was more worried about the family members than the threat of ghosts. Butterfly Ninja: Alas, Kazuki is flirting with women again? Well, I'm not angry, I'm really not angry. Kanroji: Husband, I am angry this time, and I will never forgive you without a hundred cherry cakes. Shanahu: There's nothing in this lunch... It's not poisonous Nezuko: Ah, it suddenly seemed like I was drinking some blood. Do you think that's right, Kazuki-nii? For fanfics, please don't overexamine the original settings.
