It had been a while since Muzan fell, long since the final battle and the survival of the Hashiras, long enough for Kagaya to have his sight and strength back. But it all changed when Kagaya found out Amane had cheated on him, and she had slept with a Kakushi. Kagaya was heartbroken...only two days later Amane left, leaving Kagaya with the children. Amane had truly given up on her marriage with Kagaya and left. The Hashiras didn't see Kagaya as often as they used to. Usually Kagaya would go to Gyomei if something was troubling him, but Kagaya didn't go to Gyomei this time. Kagaya had stumbled upon a woman, dark tan skin, she had a very curvy body, black eyes, and long brown hair. Kagaya ended up talking just as Kagaya, not the leader of the Demon Slayer Corps. It helped him a lot, he ended up talking with her more often. But little did y/n know, she was speaking to her elder brothers Master, little did Kagaya know, he was speaking to Gyomei's little sister.
