Ever since the Mugen train incident, Kyojuro has made you his Tsuguko. Training you, and training you. Yes, it was hard and sometimes harsh, but it was so full of passion, he had so much faith in you, and you knew he meant well. So, you never quit. You would train so hard, that you couldn't move certain parts of your body anymore. After 6 months- 6 months after the Mugen train, and training, autumn has fallen upon Tokyo, Japan.

When you were too young to remember, your parents had been killed, and you had lived with the Kamado's, because Kie Kamado and Tanjuro Kamado had found you, injured, and crying. But after they died and Tanjiro Kamado started training, and went to Final Selection, you still hadn't passed training. You couldn't split the boulder. So, Urokodaki wouldn't let you go to Final Selection. He didn't think you were ready. So instead, you traveled with Tanjiro, and fought in different ways. Like Nezuko. But after Kyojuro saw you fight strongly on the Mugen train, shedding your own blood to help protect the 200 hundred passengers on the train, and survive a knife to the neck from saving Tanjiro from being stabbed, then yelling at Upper 3: Akaza when he got away from the sunlight, leaving Kyojuro heavily injured on the brink of death, a smashed left eye, never going to be able to open it again, and a hole through his stomach, he knew you were good-hearted, and had potential.

One night, the memory of your parents being killed haunts your dreams. Kyojuro's peacefully sleeping on his futon in his room down the hall of the Estate you share. He's not a light sleeper, but he's not a heavy sleeper, either. But, he's unaware of your terrors in the night. You woke up in a cold sweat, shaking and breathing heavily.

You don't want to sleep alone right now.
