The Snakes Prey, Tomioka Y/n (Obanai Iguro X Fem! Reader)

Y/n, the sibling of Giyuu and Tsutako Tomioka. She was pronounced dead at the final selection which was of course untrue. Y/n was simply helping Sabito defeat a demon which they unfortunately failed to do, Y/n told Sabito to run away with Giyuu he denied her saying but Y/n pushed them both out the way and continued to battle the demon. Everyone survived but Y/n...or that's what they thought.

Y/n Tomioka is indeed alive, once she becomes the rose pillar what will be her brother's reaction along with his best friend? what will the pillars think about her?

What will the Serpent Pillar think of his enemies sister?
