☁︎︎ Third POV

Both Rengoku and Y/n came to a stop when they saw a familiar burgundy hair. Y/n crouched down next to Tanjiro while Rengoku stood by Y/n. Tanjiro looked up and was shocked to see Y/n and Rengoku standing side by side.

'We're they one who made the train move from the back?!' Tanjiro thought in shock.

"Tanjiro!" Y/n called out.

"Kamado, my boy!" Rengoku greeted.

"Rengoku-San! Y/n!" Tanjiro shouted in shock.

Rengoku kept his upbeat smile, "Me and Y/n managed to land some very minor slashes before coming here!"

"We think that the demon will take some time to regenerate," Y/n added.

"But there's no time so we'll talk to you quickly!! This train is made up of 10 cars, me and Y/n will protect the back seven!"

"Nezuko and Zenitsu-San will protect the other three."

"Right! So that leaves you and boar head by to go for the demon's neck while watching out for the front three cars!!" Rengoku stated.

"Neck?! But now the demon's—" Tanjiro was cut off.

"It doesn't matter what he looks like! As long as he is a demon, he'll have a neck!! Me and Y/n are also looking for a weak spot while fighting him! Time to get fired up, boy!!"

"We're counting on you, Tanjiro-san!" Y/n yelled over the sounds of the train.

Tanjiro didn't have time to talk back as Y/n and Rengoku disappeared from sight. All that was left behind was a line of fire and clouds - turning into smoke - leading to the ends of the train.

'Th-They're so fast!'

Smoke and fire raced each other until they both noticed the flesh eating the sleeping passengers on the train. Y/n and Rengoku came out of the fire and slashed at the flesh, splitting them into very little, and almost unseeable pieces.

Y/n jumped back from his spot in the cart and him and Rengoku pushed their backs together. To a normal human being, they wouldn't be able to hear the small conversation the two were having because of the speed, but to them it was just enough time.

"Split up! It'll be fast to slash that way!" Rengoku stated.

Y/n nodded, "Let me use your back, I'll be able to get to the other end faster!"

"Hai!!"

Y/n jumped up and used Rengoku's back as a surface to propel himself to the end of the train. Rengoku's eyes slightly widened at the force of Y/n legs, but he quickly shook that off and ran to the other end of the train to slash away the flesh.

Smoke and fire danced with each other as Y/n and Rengoku constantly passed each other to switch carts over and over again. They were fast, too fast for the flesh to keep regenerating over and over again.

At one point, Y/n had to stop in the middle of the carts to slash at a piece of flesh. He did so without worry, but when he turned around he was met with an eye looking right at him. Y/n's eyes widened as they turn white and he fell backwards, into more flesh that was starting to surrounding him.

"Y/N!!" Rengoku's voice shouted as it was the last thing that Y/n heard before passing out for a second.

"My, my~ So this is the mate he was talking about," A new voice cooed into Y/n's ear.

Y/n's eyes opened in shock. He looked around and it seemed like he was in a void of a dream. He tried to move his limbs but they were stuck. One of his arms were over his head, the other on his side, and one of his leg were open.

"I'm so glad that I am able to met you, in person~" A demon emerges from the darkness and was standing right in front of Y/n with a heavy blush on his face.

Y/n said nothing and continued to try and move but couldn't. He gritted his teeth and narrowed his eyes at the demon.

"The name is Enmu, darling~ And my, my, you really are beautiful~ You petite face, you loving eyes everything about you is just so... memorizing~" Enmu cooed and stroked Y/n's cheek.

"Get off of me! I am no mate to anyone! I don't belong to anyone!" Y/n shouted as he shook in place at the familiar and unwanted feeling of lust.

Enmu fake pout but smiled, he went closer to Y/n's face and licked his lips with hunger, "You're so strong, so brave~ Yes, I wouldn't mind if you take me~"

Enmu lowered himself and was near Y/n's crotch area. He gently stroked Y/n's abdomen with one hand as the other was caressing Y/n's thigh. Y/n's breathe hitched as an unwanted blush appeared on his cheek.

"You know, I didn't mind putting that water-poison in you~" Enmu stated, "I get to know where you are at all times now. I'll be able to find you, hunt you down, and make you mine. You'll love it, you'll love me~ You'll love all of us, I promise~"

Y/n had a small tear in his eye as he could feel Enmu touch his crotch very softly and wanting-ly. He bit the inside of his cheeks to prevent himself from letting out a groan or a whimper. He shut his eyes wanting this to be over.

"My love, my dear, you'll soon to realize that our love for you in infinite~ You know, your little friends of your dreamt a dream about you being theirs, but I can make mine a reality now that I have you here~"

Enmu raised himself and pressed his crotch onto Y/n's thigh, grinding himself. He let out a soft moan and looked at Y/n in the eyes. He caressed Y/n's jaw and pulled himself closer to him as Y/n tried to pull away.

"St-stop this... I don't want..." Y/n stuttered out.

Suddenly, there was a burst of flames. Enmu's and Y/n's eyes immediately widened at what was happening. Enmu hissed at the sudden feeling and had no choice but to pull away from Y/n. A fire red and black sword came down on Enmu's shoulder making him scream.

Enmu was suddenly behind Y/n and was holding onto him for dear life. He didn't want Y/n to leave him just yet. He wanted to be with Y/n forever, he wanted Y/n to stay with him!

Enmu let out a screech as Y/n was being pulled away from him. Y/n's coldness left Enmu and he was left with his arms opened in wanting and his hand outstretched to Y/n's back, wanting him to come back.

"Y/N!!" Rengoku shouted as he pulled Y/n out of the flesh that was holding him captive.

Y/n gasped and snapped his eyes opened. He was roughly thrown to the ground because the amount of force Rengoku had to have to pull him out. Y/n coughed and choked a bit as he had terrified eyes.

Rengoku was quick to slice the flesh around him and Y/n. He quickly kneeled down Y/n to see if he was okay. His smile was no longer present as he was very worried for the smaller male before him.

"Y/n!! Are you alright?!?! You're not injured are you?!?" Rengoku shouted in pure concern.

"H-He was... He was about to r-rape... Just like last time... He was about to have sex with me... Just like what Muzan was about to do... He-He... I can't... I can't breathe..." Y/n panted out as the world around him began to swirl.

Rengoku's eyes widened, they than turned into one of pure anger. How dare a low leveled demon such as this one put their hands on Y/n. That was purely unacceptable, it was horrendous!

Rengoku got up from his seating position and turned to the flesh that was going after Y/n. Y/n was still on the floor, pulling his collar away from his neck to breath better.

"How DARE YOU!!" Rengoku shouted as he raised his blade, "HOW DARE YOU TOUCH SOMEONE SUCH AS Y/N!! I'LL BRING ON HELL FIRE TO YOU, NO MATTER WHAT!!! YOU SHITTY ASS DEMON STEPPED TOO LOW TO GO AND RAPE SOMEONE!!!"

Y/n's eyes widened at what Rengoku had said, and it was with so much anger, it was scary yet comforting in a way. He watched as Rengoku slashed away all of the flesh that had the seven cars in their hold. They were all gone and Rengoku was back next to Y/n in a flash.

Y/n eyes' were still in shock at how fast Rengoku had went. All around him was now flames that were slowly disappearing. He slowly turned to Rengoku who turned to crouch next to him with a worried look.

"Y/n... I'm so sorry, are you okay now? I promise, after all this, I'll make to take care of you," Rengoku stated.

Y/n's eyes shined at the caring-ness Rengoku had for him. He quickly engulfed Rengoku in a hug and silently sobbed into his shoulder.

"Thank you... Thank you so much Kyojuro..." Y/n managed to say, "You did so much. Thank you, thank you, thank you."

Rengoku's eyes widened at the sudden affection. His eyes then shined in appreciation and he blushed a bit at the contact. He slowly wrapped his arms around Y/n and held him close.

"Of course Y/n... I'll do anything for you, absolutely anything," Rengoku said as he comforted Y/n - his sobs reducing.

"Kyojuro, thank you, I really, really mean it," Y/n claimed as he pulled away and closed his eyes in a happy manner, his lips twitching a bit.

Rengoku's eyes shined but then he too began to smile, "Yes, you are very welcome Y/n. I just want you to be safe from now on, so I'll protect you."

The two stayed holding each other's embrace for a bit. They didn't need to worry about the flesh because Rengoku had slashed them all and it was going to take a while to regenerate after the rage Rengoku had went on.

The train then suddenly wobbled terribly, side to side. Rengoku held onto Y/n in a protect manner as Y/n wrapped his arms around Rengoku's neck.

"Looks like my boy Kamado managed to get the neck, I knew he could do it," Rengoku stated as the train was about to fall, "Hold on tight, I shall protect you..."

Y/n said nothing, he didn't need to, he just held onto Rengoku tighter as he sheathed his sword and Y/n did the same. The train began to tumble, Rengoku shielded Y/n as much as he could as the train started to land on it's side.

The train tumbled and spun a bit, Rengoku held onto Y/n tighter for safety. It landed with a bang onto the floor as it slid to a stop. The two males still holding onto each other for protection.
