As a candidate to be the Serpent Pillar, Obanai Iguro's apprentice, your life is no longer the life it once was. As the possible future apprentice of the serpent pillar, you and Obanai will be spending a lot of time together, but little do you know all the hardships this will bring. Will you succeed to became his apprentice? Or maybe something more...? I do not own Kimetsu No Yaiba or any of the images Disclaimer: this is an au! theres stuff that doesn't match with the lore so ofc its going to be different! thx for understanding <3
