Its been months since you seen Rengoku, you’ve kept in touch, facetiming every now and then, he never stoped checking in on you and Giyuu (or whoever u wanna date), Rengoku had his own life now since retiring from the Demon Slayer corps, him and Tengen started hanging out more, he got married and even had his own kid now, you decided to visit him at his estate, you knocked at the door and his wife answered, she smiled and hugged you, Rengoku then came to the door and smiled brightly, he hugged you tight and looked at you

Ah! it’s been a while hm! I’ve missed that bright young face of yours!!

Rengoku’s child came waddling to him, Rengoku picked up the Yellow haired child and smiled

This is my little flame! She’s cute isn’t she? Anyways young one! How’s life at the Corps?
