Kamado Tanjiro had a hard life going on, he was currently in a depressed state. The wooden box on his back was empty, his sister, his dear lovely Nezuko died...

How? Well, he had kept his sister alone in a house. Hoping to be back soon after getting some food for himself. But sadly, as he came back his nose picked up on the smell of blood and... ‘Whenever happiness is destroyed, there's always the scent of blood...

And sure enough, as soon as he reached home Tanjiro saw the scene. His dead sister. It shouldn't be possible! She was a demon, she should regenerate. But it never happened.

Walking through the forest, it was as if Tanjiro had lost the motivation of his whole life. The once bright eyes, were dead. But that's when he saw a demon, sleeping.

Tanjiro was about to go there, and slay him. Not wanting to fight much and end the demon quickly, but as he was about to, Tanjiro was surprised. ‘The scent, he doesn't smell like he has eaten human at all...'

Looking closer, he couldn't help but notice how adorable the demon looked. Like Nezuko... Tanjiro then had a dark idea, slowly he approached the demon, taking out the bamboo muzzle he carried, of his late sister.

Slolwy he put it on that demon's mouth. You were sleeping, so you didn't know what he was doing. And in your subconscious you let him put it on your mouth. After he did that, he stroked your hair.

‘He, he will be my brother...I won't loose him now. He- he will always be with me. I won't repeat my mistake.’

With that, he picked you up slowly and put you inside the box on his back. And closed the door of the box, feeling the weight, he felt a sense of relief.

“You will never leave me...”
