An Unbreakable Bond (Demon Slayer Harem X Reader)

Chapter 2: Once Human, Now Demon

There was hardly anytime to react as the person with the katana lunged towards Nezuko with the intent to slice her. However, Tanjiro stood up and shielded his sister, causing the person to stop in their tracks.

"Why are you protecting that thing? You know what it is don't you?" His expression and voice were cold as you stared Tanjiro down.

"She's my sister! I was taking her to get help! P-please, she isn't like the others! There was another scent at my house! That's probably the demon that killed my family!" You felt your heart drop at his words.

"The demon....it killed his family too? They...are the only two left?" You covered your mouth as the man with the katana switched between Tanjiro and Nezuko and then you.

"And who are you? Why are you here?" He asked with some suspicion.

"I-I'm....Tanjiro's best friend! A-And if there really is another demon out there that did this ti Nezuko and killed his family, then it must've killed my mother too!" Tanjiro gasped softly as the man raised his eyebrow.

"I....do apologise. But you still shouldn't be here. No matter who she was when she was a human, that girl is now a demon. It is my duty to slay her so she doesn't eat any humans." He gripped his katana and lunged towards them again. Tanjiro ducked and tried to shield Nezuko too, but when he looked in his arms, she was gone.

"I can't turn back time! If only I was here sooner, maybe your family would still be alive and your sister would not be turned into a demon! I know it painful, but I have to do this! For the greater good!" He raised his sword and plunged the blade into Nezuko's shoulder. She let out a blood curdling scream as Tanjiro cried out and threw a rock at him.

The boy then picked up the hatchet that he had earlier and started running around in between the trees, in order to try and put off the guy with the katana.

Having seen enough, you knew you had to step in and help as well. You picked up a nearby rock and threw it at the man as well to see if it would catch him off guard.

However, his reflexes were quick and he deflected it. This gave Tanjiro an opportunity to charge right at him and go in for a proper swing.

But still, his reflexes were lightning fast and he hit Tanjiro on the back of his head with the hilt of his katana, knocking him unconscious.

"Tanjiro!!!!" You clenched your fist and ran towards the man who was struggling to keep Nezuko in his grasp.

Eventually she got too strong and broke free. She made a break for Tanjiro and stood in front of him, to protect him.

You could see the look in the man's eyes change as he lowered his sword. Seeing this made you skid to a halt, which resulted in you slipping and falling to the ground.

"I....don't believe it....she could've devoured him....but she's protecting him...." You heard him mutter in disbelief as Nezuko growled and lunged towards him.

He dodged her moves and attacks as the look on his face seemed to be one of that he was in deep thought. Eventually though, he chopped the back of Nezuko's neck which knocked her out.

In the meantime, you had made your way over to make sure Tanjiro was alright.

"Okay yeah....j-just sleeping is all....." You gently pat the boys back and sit down in the snow next to him. "I-I'm so sorry Tanjiro....I-I wish there was more I could've done. B-But....I-I am glad that at least you weren't there when it happened. Y-you could've been ki-...." You broke down into tears after that, as you heard Nezuko being placed down on the ground next to you.

Looking up, the man had sheathed his katana and sighed. "They will both be fine. Just sleeping for now."

You nodded and wiped your eyes while trying to compose yourself. "W-who are you? Y-you're a Slayer right?"
