𝓣𝓱𝓮 𝓡𝓸𝓼𝓮 𝓗𝓪𝓼𝓱𝓲𝓻𝓪 (Severus Snape x Hashira! Reader x Giyū Tomioka)

Introduction:

Y/n L/n was one of the Hashiras of the Demon Slayer Corps. . Beautiful and enchanting as one might say. She was also well like by her cheerful nature and kind nature. However, behind that mask with the smile she worn hides a secret. Her fellow Hashiras, have a high respect for her. However, everything will changed when a mission goes wrong as some Demon's blood demon art sent her to another dimension. What she didn't know this dimension will change her life forever by a certain Potions Master, who caught her attention. However, a certain Water Hashira has also caught her attention. Will love blossom? Which will she choose?

A/n: Rose breathing is not my own technique. This was created by someone in amino so I'm going to the credit the creator. Most of the Rose Breathing techniques goes to the original creator. The characters of Demon Slayer belong to Koyoharu Gotouge and Ufotable while characters of Harry Potter belongs to JK Rowling. Also I I only own Y/n who would go from 15 but she'll age as the series go by and some characters that didn't appear in the Harry Potter films and Kimetsu No Yaiba.

Update:
I was skeptical whether or not should post it here from Tumblr but I thought why not.
