It was all because of a one night stand you two had when you and him were seventeen. It got you pregant, and he stayed for the baby.

You fell for him and then married him. He broke the news of being a hashira to just before the wedding. And.. Being the flame hashira's wife was almost amazing. When your baby was born, senjuro couldn't stop gushing about him and shinjuro only hated you. But was glad to see his son so happy.

When you went to the Mugen train with him, you saved him by just interfering. You called out to him and clung to him. Upper rank three, Akaza, just stared blankly before quickly leaving. Huh?! Tanjiro, Inosuke and Zenitsu chased after him, heck, even nezuko! But no luck.

He told you what Akaza had told him, to become a demon. Kyojuro had alot of wounds, so you toke him home where you and his child said their first word, "Umai!" Probably heard it from Rengoku eating your food but it made you, Rengoku and senjuro laughing your asses off. Currently, you and him are twenty and your kid is three.

Kyojuro trained, and trained, and trained. To get back his hashira rank. You and your child are sleeping in his bed, waiting for him until..

Akaza: Don't train too hard~! You might open that wound again, Kyojuro~!

You got up and ran outside.
