Sister of the snake - Tanjiro X Reader

CHAPTER 24

A/N: I'm sorry that it's been taking me so long to update, I've been very busy recently. Please forgive me! Anyway enjoy.

"Lives that have been lost will never come back. They will never return."

I could see that Tanjiro was losing his cool, and while it was good for the moment because of his power-up, it wouldn't be good down the line. He might even be permanently affected if this continues for too long. But I still wasn't satisfied, Tanjiro didn't have enough control over his power.

"Living, breathing creatures do not go the way of demons. Why do you take them? Why do you trample on people's lives?"

The demon held her head in pain, seemingly remembering something something. I did too. I had regained my memory of my past life hundreds of years ago slowly over time, but mostly while pretending to be an oiran.

Flashback:

Me and my older brother, Yoriichi, stood over the cowering Muzan. I finally summoned the power to speak in his presence, my words filled with acid.

"Living, breathing creatures do not go the way of demons. Why do you take them? Why do you trample on people's lives?"

Muzan growled. Yoriichi then spoke, his cold words resonating deep in the demon's brains.

"What's so fun about it? What's so enjoyable? What do you think lives are?"

"Why don't you know?"

I asked.

"How could you forget?"

Yoriichi asked. I finished rubbing salt in the demon king's wound.

"You were probably human too, once. You must have struggled with pain and suffering and shed tears."

Flashback end:

Tanjiro was mirroring me and Yoriichi's words from that time. I couldn't help but smile. I must have really taught Tanjiro well.

The demon, probably irritated, slammed her fist into the roof we were standing on, making a hole in it.

"Blah blah blah blah, just shut up. I don't remember anything from my human past. I'm a demon now, so the past has nothing more to do with anything."

"How sad..."

I said, blitzing behind her. She tried to hit me with one of her cloths, but I just grabbed it.

"So sad that you think that way. So sad that you've lost your memory. It's devastating, really. You don't even know who or what you're fighting for. You're fighting for Kibutsuji? Please, spare me the nonsense. I honestly don't believe this could be true, because he's just manipulating you."

"Shut up! Demons don't age. We don't need money to eat. We don't fall sick. We don't die. We don't lose anything. And strong, beautiful demons can do anything!"

She said. I snorted in disbelief.

"You don't die? Sure, sure, tell that to upper moon 3. Oh, wait, I killed him, oops, I forgot."

I was messing with her, I could never forget the burning rage that drove me to punch that demon until the sun came up and finished the job. I would never forgive him, and I would chase the demons to hell if it meant I could make them pay.

"Alright. Enough."

Tanjiro said. He leapt at the demon, but she launched multiple of her cloths at him.

"Blood demon art: S-"

Her head fell clean off of her head. I had cut it off.

She screamed in pain. Tanjiro skidded to a stop in front of her. But something was wrong. Her body wasn't disintegrating like it should. It was still.

"Damn you!"

She yelled. Her body disappeared, but it wasn't disintegrated. She had moved somewhere. I could hear quiet sobbing from the room below, alongside a creaky voice reassuring her that it would be okay. But I had bigger problems, because Tanjiro fell to tge ground and started coughing up blood. I ran up to him and checked his vitals. His lungs were severely damaged. I needed to get him to the Butterfly mansion, and quick.

Two people appeared. I could see that one was the demon from before, but the other one was what scared me. He was long black hair that faded to green at the tips and dog-sh*t-like birthmarks all over his face. His waist was unnaturally thin and his ribs were plainly visible. He had two sickles in his hands.

The demon from before had reattached her head. How, I didn't know. But she did.

The female demon ran at Tanjiro, while the man ran at me. Before the girl could reach Tanjiro, however, she was kicked away. The male stopped in his tracks, and yelled,

"Daki!"

So that was her name. Daki.

Nezuko was standing over Daki, growling. Black veins appeared by her left eye, and she stalked towards Daki like a hunter stalking it's prey in plain view. Daki regenerated the head Nezuko kicked off, and growled.

"O-oh! It's you! The one master specified!"

She then seemed to be talking to herself.

"Y-yeah! I'll torture her to death if it pleases you!"

Nezuko leaped at Daki, but the latter sliced off the former's leg, arm and upper body, launching her into a nearby house. Nezuko regenerated and ran at Daki again. The male who had been with Daki before tried to help her, but I blitzed behind him.

"Not happening. I'm your opponent."

He growled and turned to me, swinging his sickle. I ducked and kicked him in his lower abdomen, although his terrible health made it hard to aim right. He swung his sickles down at me, but I deflected both with my sword, kicking his abdomen again.

We heard a crash, and both me and the male looked at where Nezuko was. More black veins were sprouting out of her left eye, and normal veins were visible all over her body. The most troubling part was the horn sprouting out of her head. There were vine patterns growing on her body resembling tattoos.

She ran at Daki. Daki cut off Nezuko's leg, but Nezuko instantly regenerated and kicked Daki with such force as to bury her foot deep in Daki's back.

I turned back to the man in front of me and leaped at him, attempting to decapitate him. One of his sickles latched onto my sword and threw it into the street. I cursed quietly and jumped onto the street, trying to get to my sword. But Daki and Nezuko were going at it, clawing and kicking at each other. I tried to get my sword but had to stop when one of Daki's cloths almost sliced through my stomach. 'Fuck...'

"Ice Breathing, second form (modified): Improved, Lateral Frozen Flash Flood!"

I blitzed forward and grabbed my sword, my hands gripping it tightly as I finished my blitz with a sword slice that cut cleanly through Daki's neck again. I wasn't surprised when she put it back on.

But the little bit of attention I gave her was too much, and before I realised what was happening, a poisoned sickle dug into my side.
