After you died Akaza went on a rampage. He killed 67 men with his bare hands. And Muzan forced him to become a demon. In truth he wanted anything but that outcome. As he planned on joing you soon. But now decades later he's in battle with Giyu and Tanjiro. They've just decapitated him and yet Muzan screams in his head for him to keep fighting. When your spirit speaks to him. And suddenly all his repressed memories come flooding back. He loved you, he wanted to be with you.. but he can't. He's going to hell he's sure of it. And you were already in heaven. It broke his heart knowing not even in the after life could you be together
