You had gone through a very traumatic even, your whole family had been killed by the wretched demon king, muzan kibutsuji, your older brother, tanjiro, was still out at night. luckily you didn’t end up as meat like the rest of your family but you were transformed into a demon. When you woke up after that you were just almost brain dead like acting on instincts, but you also woke up with new… assess as well.

Your waist and upper body had gotten smaller and thinner but your lower half had the opposite. Your hips are grown wider and thicker, your thighs were large and meaty, but your ass was the main focus it was large, round, fat and so soft as well..

Ever since that day you have stayed by your brother’s side and he became a demon slayer! At first it was weird as him being a demon slayer while you were a demon was quite weird but it got better..

Soon you went through many difficult journeys and adventures together. While through one of his missions you were walking through a village and your brother met some other fellow demon slayer friends, one of which was Zenitsu and he was extremely obsessed with women. Once he laid his eyes on you, he fell in love with you due to your new curves, he never thought of himself being with another person but you.

Over time it got quite normal and it was still pretty annoying to see him gauzing at your curves and face. It was an one of Tanjiro’s missions days, so he left you alone in the butterfly mansion with Zenitsu and Inosuke..
