Akaza is fighting Tanjiro and Giyu when a light and tender hand takes his. He turns his head and sees yours. It makes his heart melt with love, and he He falls to his knees, tears streaming down his face, his arms wrapping around your hips, and his head burrows into your stomach

Akaza: I'M SORRY!!! FOR LEAVING YOU ALONE!!!!! I JUST WANTED TO PROTECT YOU!!!

You smile at him, and then your mind transforms into a person. You've returned as a human. Akaza looks up and his eyes widen. He can't believe you're alive and actually standing in front of him. Tanjiro and Giyu also look astonished. You just smile at Akaza and rub his head. The guy is still on his knees
