Together with the others Hashiras and the Kamaboko Squad you fought and defeated all the Upper Moons and Muzan, you also saved Shinobu from Douma before it completely absorbed her. After weeks you ended up falling deeply and madly in love with each other, and you became a couple, and soon after even getting married, after killing all the demons

One day while you were walking in the Demon Slayer Headquarters, leaving your wife sleeping alone in the bed, since you had nothing to do, when you felt someone hugging you from behind, two very small hands caressing your entire torso

"Ehy, why you didn't even tell me you were here? I though you were still in the futon with me... are you becoming a loner?"
