The Boy of Two Breaths (An Oc x Kimetsu No Yaiba Story)

Yes we are doing another story! our first Demon Slayer one! we were thinking of doing it a while ago but we weren't confident....especially since I never watched Demon Slayer at the time but Blue did at least

Yes Blue is the OC and yes this is a Harem story....I am the number one Wingman after all!
