Little Demon, why can't I kill you?

Tanjiro, Nezuko, Inosuke, and Zenitsu all collapsed onto their respective beds in the infirmary house. They had just been double checked by the staff to make sure each of them were actually healthy and properly healed up.

It had been an eventual adventure for sure.

Having to dress up in drag for the mission, face off two demon siblings, and Tengen Uzui’s retirement means that the demon slayers are down another Hashira. At the very least there is a bit of a happy ending to it all, the demon siblings finally got a chance to move on and Uzui was still alive.

It's the little things to be thankful for. Even if, technically, it's big.

Though Tanjiro's true mission, gathering up high ranking demon blood to help Nezuko return human, was set back once more. He knows he should be grateful for being alive, yet it feels like obstacles keep getting in the way. Even if they win and survive, Nezuko was still stuck in her own torment.

Falling into an uneasy sleep, Tanjiro wishes something, or someone, could just help him on his mission to cure his sister. _________________________

The trio sat in front of Hashira Kocho, as she looked over their notes of the previous mission.

Glancing over at the three boys, Kocho placed her hands softly on the table. Knowing they worked hard and risked a lot, but missions have to keep getting completed.

"Well, I can tell you all this much, every one of you is healthy and ready to go back into the field." She told them with a smile.

Zenitsu groaned about wanting to rest up just a bit more and maybe hang out with the girls for an afternoon longer. Inosuke yelled in excitement, being ready to hunt more demons and not have to wear ugly clothes anymore. Tanjiro smiled softly, staying silent with his head slightly tilted to the floor.

Observing each, Shinobu Kocho pulled out the information for their next mission.

"And I'm happy to say it's going to be an easy one in comparison to what you have dealt with so far. You’re tasked with finding the Nightgale family and bringing them back to the Butterfly Mansion."

"Um, excuse me Miss Kocho, but who are the Nightgales?" Tanjiro's soft voice echoed in the small room.

"Ah, well where to begin. The Nightgales are one of the oldest demon slayer families. They were, in fact, the ones who figured out what metal could be used to fight against demons, and from there they branched out. Throughout the generations they have been doctors, scientists, slayers, craftsmen, magic users… really everything but cooks. Their entire livelihoods have been built on studying, and slaying, demons." Kocho's lips culled at the last statement as she watched Tanjiro almost jump at her words.

"Study? They actually studied demons? B-but how?! What have they learned? Are they willing to take an apprentice or share what they know?" Tanjiro asked question after question, only quieting down when Inosuke interrupted him with a tackle.

"Will you shut up, Tarongi! you ask too many dumb questions." he growled.

Laughing softly, Shinobu gently pulled on her sword. "Boys, no rough housing in my office."

In an instant both Inosuke and Tanjiro sat properly.

"Good. Now, as for your questions you'll have to ask them in person. The most I know is the latest Dr. Nightgale's have been studying demon blood and physiology, with their only child Jasmine recently finishing up her training to be a demon slayer herself in the last year. The reason you’re heading to meet them is because within that time frame the Nightgales seem to have vanished without a trace. You are to investigate why that is, bring as much information about their research back to the Hashira, and bring with you the Nightgale family as well in case they are in danger."

Tanjiro agreed with newfound determination in his eyes. He was ready to go right this moment and nearly bolted out of the door when Miss Kocho raised her hand to stop him.

"Now, I want you three to know some important information before you head out. The Nightgales are very hospitable to other demon slayers, but the moment they even suspect you're a demon they will not hesitate to attack, capture, study or kill you where you stand. Over the past 13 years they have been more paranoid about demons designing themselves as humans, so tread carefully. especially if you're wearing a mask, flirt, or have a demon with you." She stared at the trio, who couldn't even look her in the eyes.

"Hmp, I'll be giving you a crow to lead where the Nightgale house is… oh, and can I ask a tiny favour?"

“Of course Lady Kocho, what is it?” Zenitsu surprisingly asked.

"Can you get me one of the flowers they've been studying? There have been some rumours that they had found a new type that when matched with Wisteria flowers will amplify the power, and burn away a demon within seconds." She tilted her head playfully.

"A simple task to bring a flower to a fair lady such as yourself Miss Kocho, it would be an honour~" Zenitsu bolted out the door to get ready for the mission. Tanjiro and Inosuke followed, not wanting to be left behind.

__________________________

Tanjiro kept his eyes on his soundings as the crow led the way. To his left Zenitsu hummed to himself as Inosuke ran around looking for something to fight.

So far their journey has been calm, all they had to do was trek though a peaceful forest path, it barely counted as a hike. Nezuko was sound asleep in her box, restoring her energy while the sun was out.

As they continued on the tree's shade became thicker as the path was slowly but surely disappearing, leaving them lost. The crow they had been following seemed to have gone missing, and with the thick underbrush sounding the trio it was nearly impossible for them to find their way.

Untamed Nature caged them, yet strangely there was barely a sound but their footsteps. Not a bird song or the trickle of water, just pure silence. Taking a deep breath Tanjiro decided to keep moving forward, leading further into the unknown wilderness.

Both Tanjiro and Zenitsu were trying to step slowly around roots and lose rocks, but Inosuke got inpatient and didn't want to be stuck going that slow until nightfall, so he took initiative as he shoved past the two boys and ran ahead. With that they gave chase after their boar headed companion.

"Inosuke, slow down! We don't even know if this is the right way!" Tanjiro cried out. Zenitsu was just trying to keep up as he held back the need to cry, everything was going so good, but his friends just had to ruin it.

It wasn't long before Inosuke had run so far ahead he was out of sight, forcing Tanjiro to slow down and smell the air to see which way he went. As he slowed down to sniff the air, Zenitsu, being blinded by tears as he tried to keep up, bumped into the other slayer, causing both of them to fall down a steep slope. Crashing and tumbling down they come face to face with the bottom of the hill, a small valley covered in trees and thorny bushes.

Zenitsu slowly pulled himself up first, his hand pressed against some kind of rope. With lightning speed he moved out of the way just before the trap could pull him into the trees, landing right against Tanjiro’s side, who groaned in pain.

Tanjiro shook his head and got up, making sure Nezuko was okay and her box intact before looking over at a shivering Zenitsu, who stared straight ahead with a terrified expression on his face. Following his gaze, Tanjiro could see traps with rotting meat hanging from various ropes and rusted chains. Magical markings drawn in dulled, red paint covered the slowly degrading building, A vibrant orange sunset illuminating the forest and house before them.

"Yo! Zunkaka, Tabiroj, about time you got here! Hurry up, it's almost night you idiots!" Inosuke shouted as he stomped over. Zenitsu took small nervous steps towards the house, which just made the boar headed man huff in frustration as he marched over and picked up his sparky friend. Tanjiro quickly gathered his sword and Nezuko's box to join them, hearing her small growls and whines as he stopped his friends once they reached the front door.

"Hold on, this place smells weird. and Inosuke, you still have your mask on! Remember Lady Kocho's warnings? Let's just wait a moment." Tanjiro begs.

"No way, we came all this way already. If they want to fight me about what I wear, let them!" With that Inosuke shoved the door open.

What they were greeted by was the smell of medicine, blood, and rotting wood. Through the door was a darkened hallway completely absent of outside light, yet a distinct small shadow sat in the middle of the floor. As they stepped forward to get a better view the child sized figure snapped its head towards the trio, glowing eyes of green and blue illuminated the hallway as red lights flickered on, revealing who was really there.

A small boy with black hair and white tips sat perfectly still, not blinking, not moving, not even breathing. His porcelain skin cracked with scars across his face and down his neck, all while an oversized blue kimono draped over his small body. If it wasn’t for an almost familiar scent of Jasmine, cedarwood, rose and strangely ice, Tanjiro would have believed they were a doll.

Tanjiro stepped forward, about to speak but stopped as the living doll opened their mouth…

A piercing screech caused everyone to drop to the ground in paralysing fear.

Made some demon!au redesigns. Vortex is grounded by his Dad Undergrowth because he wouldn’t stop scaring the human farmers.

  I know we talked about Sam being a witch and obviously Danny being half demon. but I feel like tucker was missing out on being included, so I made him and his family werewolves. It’s not until Danny gets mixed up in this mess that his best friends secret comes to life.
