You held the Tessaiga in your hands, trying to figure out which one would attack you first. "So this is the mutt? I don't see anything special about him."

"Just focus on returning with him." The eye demon said with a smile. "I have a feeling underestimating this mutt will cost us."

"They're after me..? No, they wouldn't walk all the way over here for me. They must be after Tanjiro and I because we saw Muzan!" You gripped Tessaiga and nodded the girl reeled back getting ready to throw her Temari ball. "You sure that is wise? Remember what happen last time?"

"We'll see! Go fetch!!" The girl threw the ball as you got ready to use 4th form because it was going straight at you, but then it suddenly went down and slammed on the ground before you attack. It then rose to hit your chin faster you could see.

"GAH-!" You were raised in the air and Nezuko started to get mad. You flipped in the air only to see another Temari ball coming for your stomach. "GAAAAAAHH—!-!"

"Y/NNNNNN!!!" Tanjiro shouted as Susamaru looked at the boy confused.

"What? You actually care for this mutt? You know he's a demon, right?" She said as Tanjiro glared at her. "Oh, you actually do, but I can tell you right now. Not as much as that girl does."

Tanjiro looked at Nezuko who was trying to contain her rage as she saw you getting pummeled by Temari in the air. "Oh...She knew... didn't she?"

Tanjiro looked at the arrow demon in confusion. "What? Nezuko knew...Y/n was part demon...? The only way she would know is if... Y/n's sister! She must have known! But... Nezuko would tell me... right?"

"Enough of the truths and reveals! I wanna kill!!" Susamaru threw a ball as it hit all around the house and a ball went through Yushiro's head.

"YUSHIRO!!!!" Tanjiro shouted and looked at Nezuko, and snapped her out of her rage. "NEZUKO!! GET THE WOMAN ASLEEP BACK THERE SOMEWHERE SAFE OUTSIDE!!! I'LL HELP Y/N!!"

Nezuko hesitatingly ran off with quick speed. You were getting dazed a bit in the air as you closed your eyes.

"Damn it!! Focus! I can do this! Just wait!" Another temari came for you and you quickly took a large breath. "3rd form! Whirling death!!"

You twisted your body into a diagonal spin aimed for the ball. Once the attack hit, purple aura came out of the blade and pushed the ball back down. The ball went towards Susamaru and landed at her feet. "Eh?"

"Shit! Shitshitshitshit!!!" You started falling down at quick speed. Even with you manipulating your demon energy, there's no chance to make it out of unscathed. "Wait! I got it!! 8th form: Demon DRAGON!!!"

You quickly raised your sword in the are and harnessed your demon energy, like always, a purple dragon rest on the blade of his sword. But this time you slashed at the ground just before to hit it, the dragon flew out of the blade and hit the ground, stopping your fall and giving you time to safely land on the ground. "ALL RIGHT!!"

"Y/N! Focus!" Tanjiro said as thrusted his sword through the ball, it still hit him somehow.

"?! There's something else going on here."  You closed your eyes and then quickly used your demon energy to open them. "Ha! Gotcha ya, bitch!"

"Tanjiro!!! I'm going after the arrow one!! Handle the ball bitch!" You shouted and ran forward at fast speed with your sword. Susamaru smirked and picked up another Temari.

"And who said you could do that?!" She threw a ball at you as you quickly dodged it and swung your sword.

"Demon breathing 5th form: Adamant Barrage!!" The Tessaiga fired a barrage of diamond shrapnel filled with your demon energy at Susamaru. She quickly got worried and gained multiple arms to block the shrapnel as the Diamond went into her arms as you sped past her. "I thought so."

"HEY ARROW DEMON!!" Your voice was heard as the arrow demon looked around as you used 8th form again to strike the demon head with your demon covered blade. Unfortunately, he used an arrow which sent you backwards, but you still cut his fingers off. "DAMN IT! IM COMING BACK!!!! GIVE ME A SEC!!!!"

The demon sighed as you appreared at him running for him again. "YOU MUTT!!! HOW'D YOU GET HERE SO FAST?!"

"I'M A DEMON!!! REMEMBER?!" You shouted and leaped at him. He raised his hand as you went to slice it.

"What a loyal little dog, I might just take you for a walk." An Arrow under you as you flipped in the air but quickly figured out a solution.

"Sorry, the only one that has the possibility of controlling me is Nezuko!" You stabbed the demon in the stomach as he quickly sent out more arrows around you. "You think that'll stop me?! I'll just spin in the directional the arrows, dumbass!! I'll need to use 10th form!! Demon breathing 10th form! DEMONIC PINWHEEL!!"

You did a quick thrust into the stomach of the arrow demon manipulating the arrows to follow your spin, before turning your blade upwards and pulling it out of the demon through the head. The speed and the force sent you up into the air, which then you uses your demonic energy and spins vertically in a circular motion, carrying the arrows too, and sliced the demon in half. You landed on the ground after flipping around.

"You weren't that much of a challenge for this mutt." You said cockily with a smirk. You saw his body starting to fade away as he shouted at you.

"AGH!! YOU DAMN DIRTY MUTT!! IF I BROUGHT YOU BACK, HE WOULD HAVE RECOGNIZED MY VALUE!" He shouted as you walked up to his head and lifted your foot.

"That Muzan bastard doesn't care for anyone." You said as he still shouted at you.

"SHUT UP! I'LL NEVER FORGIVE YOU! NOT EVER! NEVER!! PLUS YOU GOT DIRT ON MY FACE!! I'LL CRUSH YOU!!" He shouted as suddenly there were arrows going through you in many different directions.

"This bastard's trying to take me down with him! Damn it! I'll have to unleash techniques fast or else even my slow regeneration won't keep up!!" You went toward as wall and quickly used 8th form and the dragon stopped you from crashing into the wall. You were them taken into the air as your body felt heavy. "Damn it!! I'll have to use it in a chain! I can't afford to get this wrong!"

You used Demonic Pinwheel to stop you from hitting the tree, you used wind scar on the wall, you used Kenatsu to stop yourself from crashing into the house, you used whirling death to stop yourself from crashing into another wall. "GAH-!  My arms! My back!! I've never done techniques in a chain like this!!! I can do them but my body can't keep up!!! Kenatsu!! Demonic pinwheel!! I have no choice but to keep going! Whirling DEATH!!!"

The arrows finally stopped and you fell down to the ground exhausted breathing heavy and your eyes were shaking all over. "D-Damn...! My..! My back!! I definitely broke some back ribs, and both my legs!!! D-Damn—! I can't even swing my sword—! No, I can smell Tanjiro's injured too! I gotta make it to him and the others...!"

You picked up Tessaiga with your canine teeth and it turned back into a katana. "I can barely stay awake...hehe, maybe I'll just... take a quick nap. NO!  DON'T FALL ALSEEP! Damn it! I'm not dying here!"

"GYAAAAH!!!" Susamaru shouted in an anguish and tears. "PLEASE, FORGIVE ME! PLEASE, FORGIVE ME!! GYAAAAAAH!!!! UNNNNGH....!!!!"

You suddenly heard movement in her body as your body pulsed in and out. "SUSAMARU!!"

Suddenly large hands came out of her mouth and her stomach as the hand crushed her head as everyone was disgusted and in disbelief. You dropped the sword in your mouth as you saw Tanjiro on the ground as well. The hands kept destroying her as you couldn't believe it. Nezuko quickly rushed to you and started waving her hands, checking to see if you were okay. You didn't even notice her, the graphic scene in front of you distracted you from that. Soon Tamayo walked over to the remaining eye. "Is..is she dead...?"

"She will be soon. It's the curse that Kibutsuji's side of demons have. You shouldn't worry. Kibutsuji's cells remain in the body to destroy the flash." Tamayo expained with a sad look. "Basically... fighting between demons is meaningless. It is impossible to strike a fatal blow... unless it's done by sunlight or the katana of a demon slayer."

"Or if you cut off the regeneration." You said as she nodded.

"However, Kibutsuji can also destroy a demon cell's." Tamayo said as Yushiro covered Tanjiro's mouth.

"Don't fall prey to Lady Tamayo's power... or you'll die too!" He shouted as Tamayo looked at you and Tanjiro.

"Tanjiro... Y/n... She is not one of the twelve kitzuki." She stated and you and Tanjiro were shocked. "The numbers of the twelve kizuki are engraved on their eyeballs. Her eyes are not marked. The other is not in the twelve kizuki either. He was too weak."

"Too weak?! I mean, I just needed a to plan to kill him but he was still super strong!!" You thought as you were suddenly picked up by Nezuko, who looked at you in worry. "Eeeh? N-Nezuko...?"

She just put her forehead on yours and held you in silence as Tamayo took a blood sample. "I have the blood. I will tend to Y/n and Nezuko. Unfortunately, on top of treating their wounds... the two also inhaled some of my spell. I'm sorry."

"Huh? I inhaled what?" You asked but Nezuko kept holding you and followed Tamayo in, your heart drops. "NO! THAT IS YOUR PLAN!!"

"...?" Nezuko was confused until she remembered your fear. You started freaking out. "...!"

"NO NEEDLES!! I'LL WALK! I'LL WALK!!" You tried to escape but Nezuko held you tightly. "TANJIRO!! TANJIRO! HELPPPP!!"

Tanjiro just smiled. "See this as a step forward in your path to romance." "YOU LITTLE SHIT!! DON'T GET PHILOSOPHICAL AND JUST SAVE ME!!!"
———————-
"Nezuko." Tanjiro said as Nezuko came running down the hall. You slowly made your way to Tanjiro side as well.

"I'm sorry Tanjiro, Y/n refused to take anything." Tamayo said as Tanjiro looked at you unamused as you looked away. Nezuko then walked over to Tamayo and Yushiro.

"Nezuko...?" Nezuko hugged Tamayo again and patted Yushrio's head.

"Nezuko has been this way for a little while... is it normal?" Tamayo asked as Tanjiro smiled.

"It's alright. She probably think of you two as our family." Tanjiro explained as Tamayo was confused.

"But doesn't the hypnosis placed in Nezuko... only make humans look like family?" She asked. "But we're demons!"

"Isn't it obvious by now?" You told Tamayo with a smile and your eyes closed. Your hands were behind your head. "Nezuko sees you both as humans, which is why she tried to protect you. She's not the only one who sees that either."

Tamayo went wide eyed as Tanjiro smiled. "I didn't like putting her under hypnosis... so I'm glad she seems to have her own.."

Tamayo started crying as you and Tanjiro freaked out. "OH! WE'RE SORRY!! NEZUKO! NEZUKO! STOP!"

Tamayo hugged Nezuko and patted her shoulder. "Thank you, Nezuko, Y/n... thank you..."

After a couple minutes, "We are leaving this city. We came too close to Kibutsuji. If we don't hide ourselves soon, it will become dangerous for us. Besides... although we were well hidden as a doctor I dealt with humans, and.. sooner or later someone would notice we are demons. Children and the elderly are particularly sharp. Tanjiro, Y/n."

"Yes?" You and Tanjiro asked.

"May we take care of Nezuko?"

"Huh...?" Your heart dropped.

"I can't say she will definitely be safe, but the danger will be less than if she went into battle with you." Tamayo explained as you thought about it.

"That's... that's true. Nezuko's probably tired of having to fight for her life. Going with them would let her have a nicer life." You thought went suddenly a warm hand grabbed yours with a gentle grip. You suddenly looked to your right to see Nezuko holding onto your hand with a determined look. "But... it would be better for you to go."

She shook her head and intertwined your fingers as you started to blush. She kept moving closer to your face and you waved your hands around. "I GET IT! I GET IT!"

She backed off with a happy expression before it switched to determination as Tanjiro smiled at yours and Nezuko's display. "Thank you for the offer... but... we'll continue to travel together. We aren't going to split up. Never again."

"I understand. Then I pray for good fortune in your war." Tamayo said as Yushiro turned around.

"Goodbye then. We will erase all traces of our presence. You should go too."

"That's right, the suns coming out, where's the box...?" You looked around as the three walked away.

"Y/n." Yushiro spoke. "Nezuko is beautiful."

You covered Nezuko's ears. "She's mine, back off."

Nezuko smiled hearing what you said as a deadly aura came out of Yushiro.

"I DON'T WANT HER, YOU DAMN MUTT!!!" Yushiro got in your face with a glare.

"WHAT YOU CALL ME?! I'll KICK YOUR ASS!!!" You headbutt as well as you two glared at each other.
————-//
"South-southeast! Your goal is to the southeast!" Your raven said quietly, Tanjiro's was begging his crow to shut up before you ate it. You carried the box again as you could hear Nezuko humming in happiness. Until....

"PLEASE? PLEASE, PLEASE, PLEASE! MARRY ME!!!" You saw a boy crying on a girl as she looked disgusted. "I DON'T KNOW WHEN I'LL DIE! SO I WANT YOU TO MARRY ME! PLEASE?"

You stared at the scene before muttering, "I already hate this guy."
