  The shimmering moon shined down on the group of half-demons and slayers as they traversed through the night. Their mission planted firmly in their minds. Tanjiro's ability brought them new hope that they would see their loved ones again. They were not sure of his full capabilities and limitations, but they were excited for what was to come in store.
  The journey from the Butterfly Estate to the ruins of the Ubuyashiki Mansion-and by that extent the Infinity Castle-wasn't too long. Rui has nestled against Nezuko, who was walking beside her brother, with Rengoku standing behind him. Zenitsu and Inosuke were trailing behind all of them, just being grateful that their friends are alive. This journey was rather silent since they were just enjoying each other's company.
  "This is it." Tanjiro spoke softly as he came to a dead stop. There in front of him stood the ruins of the Ubuyashiki Mansion and the Infinity Castle. The egregious sight of piles of broken wood and shattered lanterns created a sense of unease and despair. Tanjiro looked back at the team then followed the slope of Kaikoma Mountain-which was a little ways behind them. "I know that this place holds many bad memories for many of us, but if this mission proves to be successful, this will be completely worth it."
  All the others nodded in agreement. "No one could've said it better, young Kamado." Rengoku smiled warmly. "We all have faith in you." Tanjiro's heart melted at the compliment. "Thank you, Mister Rengoku." With that, the team of slayers entered the ruins.
  The scent of day's old blood hit Tanjiro's nose as they shuffled through the broken pieces of wood. This frustrated him. Why did the final battle have to happen like that? So much sacrifice, grief, and death could've been prevented if...Tanjiro shook these thoughts away, focusing on the various scents around him.
  "Tokito.." Tanjiro closed his eyes, shedding a single tear. Rui and Nezuko rumbled worryingly. "Are you alright, Kamado?" Rui asked with a hint of regret. "I'm fine..just a lot of bad memories. He's the only one that I'm completely sure I can bring back here." The small spider demon could hear the pain in Tanjiro's voice. "I'm sorry.." Nezuko looked at Rui when he said that and held him closer.
  Inosuke was busy busting woods-despite Zenitsu's protesting-while Rengoku was carefully searching through the rubble. Tanjiro closed his eyes, taking a deep breath. He sniffed the air and opened his eyes in a flash. "They way!" Tanjiro almost roared as he started to run through the wood. The others seemed hopeful because of Tanjiro's sudden determination, so they ran off with him.
  Various red specks swirled around Tanjiro, but the scent of the young Hashira was overpowering. A soft, minty scent filled the air as Tanjiro and the others ran. Eventually, they came to a spot where large pieces of wood had fallen on top of each other. Underneath all this wreckage..was Gyomei's haori peeking out from the bottom. "We found him."
  All the slayers drew out their swords and ferociously cut through the wood, being careful not to be careless. Rengoku backed up from the wreckage. "Stand back!" The others sprang back as the Flame Hashira plowed his body through the rest of the wood. He landed in another pile of destroyed wood then looked up to see what that action did.
  Everyone gasped when they saw the young Hashira's body. Muichiro's eyes were closed with blood covering his skin and hair. Gyomei's haori covered his severed bottom half..truly a depressing sight to see. "We need to find his bottom half." Tanjiro winced, holding back vomit and tears. Inosuke looked around at his right side. "Is this it?" He pulled on a foot that was stuck underneath some rubble.
  "That's it." Despite the fact that Tanjiro was now feeling ill, he still pulled out the lower half of Muichiro. Blood dripped everywhere as he placed the young Hashira's half to his top half. "I can't believe this happened to him. He was too young.." Zenitsu spoke gently. Nezuko nodded in agreement, trying to hold back sobs. Tanjiro covered the split in the young boy with  Gyomei's haori. They all wanted to puke.
  "I'm so sorry, young Tokito." Rengoku spoke softly. "You must've suffered greatly." Tanjiro took another deep breath before slitting his wrist once again. The blood dripped into the young Hashira's maw. All of the slayers knelt down beside him. Tanjiro, Nezuko, and Rengoku even prayed for the young boy's return.
  Within a matter of minutes, the flesh between the two halves started to reconnect. They all looked up when they heard the sound of a soft heartbeat. The skin on Muichiro's arm then tore open and two long, blade-like spikes-one on each arm-rose from the rips. The dark blue spikes were curved like Obanai's sword and had swirl patterns all along them.
  Fangs emerged from Muichiro's maw and the split in his body formed a long scar that went around his waist. It was then that the young Hashira slowly opened his eyes. "Ugh..Where am I?" Muichiro groaned as he sat up. Everyone, even Rui, smiled when they saw the boy come to life.
  "Tokito.." Tanjiro whispered, holding back tears. Muichiro looked around him, seeing Rengoku. "Am I in the afterlife?" It hadn't hit him yet that Rengoku had horns and flame marks. "Not at all, young Tokito!" Rengoku drew him into a strong hug. Muichiro was taken aback at first, but eased into the hug. "Wait..then how are you here? How am I here?"
  Tanjiro scratched the back of his neck. "It's a long story. I'll explain everything when we get back" He didn't want to overwhelm the young Hashira. Muichiro looked down at his new spikes. "Am I a demon?" Nezuko shook her head. "Not really..We're kind of a new species." Muichiro was in complete shock. "Wait, what?!"
  A crow came flying in and landed on a broken piece of wood above them. "Caw! Caw! This is true! Master Kiriya even came up with the definition and name! From this moment forward, this species will be referred to as half-demons! They don't need to eat humans, don't have bloodlust, and they have their humanity! We're still trying to figure out the rest of the details! Caw!"
  They all looked up at the crow. "Hey Matsuemon, can you bring Mister Shinazugawa and Mister Tomioka to the Master's mansion? Along with all the Hashira's crows?" Tanjiro smiled warmly at the crow. The bird cawed. "I don't see why not! They will surely be surprised! Caw!" The crow flapped his wings and took off.
  "Ginko will be happy to see me." Muichiro smiled softly. "And so will Genya." The name of the young slayer made everyone's heart hurt. Muichiro looked at them, confused. "He's back at the mansion, isn't he?" Tanjiro shook his head. "He..didn't make it." Muichiro's eyes widened with shock. "Genya..died? Can you bring him back?" The poor boy sounded like he was on the brink of tears.
  "I'll try. I can't make any promises." Tanjiro stands up and sniffs the air, looking for his scent of pine. He made a soft chuffing sound and ran through the broken wood. Rengoku carried Muichiro as both they and the others followed Tanjiro. It was a good thing that they all could run quickly since Tanjiro was wasting no time getting to the center of the scent.
  They eventually came to a small clearing. Tanjiro saw the same red specks as he did when he brought Rui back. "He must've been turned right before he died." Tanjiro said to himself. Nezuko turned to the others. "It's best if we get back. They nodded and stepped back into the rubble.
  Tanjiro cut his arm open with his claws, letting his blood drip onto the floor. The specks glowed brightly and they moved closer to the blood. Tanjiro closed his eyes, raised his arms, and focused on his memories of Genya. From the time at the Swordsmith Village to training with the Hashiras. All of this made the half-demon tear up.
  The red specks circled around him, just like they did at Mount Natagumo. They started to come together to form a being. Everyone's eyes widened as they watched the spectacle in front of them. The red ashes came together like a puzzle to form the young slayer. It looked like Genya was laying on the ground, which everyone presumed that was how he was when he died.
  Tanjiro lowered his arms when the red light of the ashes seemed to die down. Genya was now visible as he was laying on the ground. He seemed to adopt the same appearance as he did at the Swordsmith Village since his mohawk had yellow tips. There was also a new scar on his face. Other than the one by his nose, he now had a long scar that split his face in two.
  Genya grumbled and made a soft roar as he sat up. He opened his eyes-and as everyone guessed-his eyes were black with yellow pupils. Tanjiro couldn't help but grin when he saw him. "Hi, Genya." The young slayer looked up at Tanjiro. "Hi Tanjiro..did you die too?" Genya seemed to be worried and tired.
  Tanjiro shook his head. "Nope. You're alive again." Genya made a surprised squeak. "I am? But how?!" Tanjiro smiled warmly. "There's a lot to explain." Muichiro leaped out of Rengoku's arms and ran to Genya. He stopped in his tracks when he was in front of the young slayer.
   "Genya.." Muichiro's voice was soft, almost inaudible. "Hi, Mui." Genya was relieved to see the Mist Hashira. Without warning, Muichiro hugged Genya, almost tackling him in the process. "Woah! You must've missed me, huh?" Genya chuckled as he patted Muichiro on the head. Everyone cheered when they saw them reunite.
  Tanjiro turned to Inosuke. "Inosuke, do you remember how Miss Shinobu died?" Inosuke put a hand to his mask. "She was absorbed." His tone was sad, yet hopeful. "Alright." Tanjiro sniffed the air again, catching  Shinobu's sweet lavender scent. "This way!" With that, he took off towards the scent.
  Everyone followed behind with a steady pace. They found themselves in another wreckage of wood, but blood and flower pedals were littered everywhere. Tanjiro looked around him to see the familiar red ashes, but this time there was purple dust within them. It was then he came to a horrible realization. Tanjiro would have to bring back both Shinobu.. and Douma.
  Rengoku seemed to realize this as well due to Tanjiro's reaction. He climbed down the broken pieces of wood to where Tanjiro was and stood next to him. He then decided to whisper something to the young slayer. "What's he saying?" Inosuke said with a bit of aggravation. "I'm not sure." Muichiro sighed, staying with Genya. Zenitsu put a hand to his ear and listened. His eyes widened with surprise and a little bit of fear.
  "Are you sure, Mister Rengoku?" Tanjiro asked with concern. Rengoku nodded. "I'm sure. He's probably going to be more than willing to help us with Uppermoon Two." Tanjiro sniffed the air, looking for a specific scent. He turned to his left and ran over the wreckage of wood and glass. He stopped in front of a certain spot where he was able to see red ashes that belonged to someone else.
  Tanjiro then performed the same procedure that he did for Genya and Rui. This time he seemed a lot more cautious. Everyone, except for Zenitsu and Rengoku, leaned over curiously to see exactly what he was doing. The ashes formed someone that the group never would've expected. Especially since both the figure and Tanjiro have had an antagonistic relationship ever since they first met.
  The form belonged to Akaza, the Uppermoon Three demon. Everyone gasped and backed up when they saw him. "What are you doing, Gaupachiro?! He's the one who killed Bug-Eyes!" Inosuke yelled angrily. Tanjiro didn't say anything because he knew something they didn't.
  Akaza shook his head like a disoriented dog. He didn't say anything as he looked up at Tanjiro. "Kamado." Akaza seemed to be in shock as he scanned over the boy's new form. "You must be..the new Demon King." He spoke in a warm and soft tone.
  "I don't hunt or eat humans." Tanjiro said flatly. "I didn't think you would. If anyone were to break Muzan's control, it would be you." Akaza smiled, much to Tanjiro's surprise. "Listen Akaza..from what I remember, you did seem like one of the demons who had-or should I say recovered-their humanity. So, I was wondering if you'd like to joi-"
  "Yes. I'll join you." Tanjiro was taken aback by Akaza's quick response. The demon's scent seemed to be filled with regret and sorrow, so Tanjiro softened his expression. Everyone else was also shocked. Rengoku seemed to realize that this was a different person than the one he fought at the Mugen Train.
  "I'm surprised that you are taking this offer so quickly." Tanjiro smiled at the demon. "Let's just say that I've made many mistakes..I don't deserve this and I know that." Akaza looked down at the ground. Tanjiro extended his hand to the demon with a smile. "Well..let's try to make things better. I know that you want to."
  Akaza took his hand and stood up. "Thank you, Kamado." He turned to see the others, who were standing on the hill of wood. "I'm sorry.." He spoke softly. Rengoku smiled at him and nodded. Tanjiro carefully led them back to the spot with the flower pedals.
  With a heavy sigh, Tanjiro cut his arm to start the revival process. He created two puddles of blood so that he can bring both of them back. The process was very similar, but there was a clear difference. The young slayer had to splice the two different colored ashes apart.
  The splicing created two forms. One belonged to Douma while the other belonged to Shinobu. The others watched with their weapons at the ready. Akaza was confused at first why Tanjiro would bring back Douma, but seeing Shinobu's form made everything make sense.
  The revival of the two beings was finally complete. They sat on their knees in front of the new Demon King. Shinobu came back with beautiful butterfly wings that had a light blue inner color while the border color was a light pink. She also had small antennae-like horns on her head. Douma looked the same though.
  Shinobu was the one who opened her eyes first. "Hm? Where am I?" She looked up at Tanjiro and smiled. "So, we won?" Tanjiro nodded silently. Shinobu looked at her new claws. "Then, how am I-"
  "Ugh! What's going on?" Douma yawned exhaustively. Shinobu yelped and hissed with anger. "Why is he here?" She looked at the others with confusion. "Don't worry, Shinobu! We've got him under control." Rengoku's voice was both reassuring and stern.
  "Huh? There's no need to worry about m-ack!" Douma gripped his chest as he almost roared in pain. He fell over as Inosuke and Akaza ran over to him. "You better not be faking it, you little shit!" Akaza snarled. Douma couldn't even speak due to the pain. Inosuke looked at Akaza. "I don't think he's faking it."
  Shinobu seemed to be a bit relieved as she stood up. "What did you have to do to bring us back, Tanjiro?" Tanjiro thought for a moment. "Well I had to separate your DNA from him. Least that's what I think happened." Shinobu nodded. "That's probably what's causing him so much pain."
  Tanjiro sniffed the air. There was a hidden painful scent. It seemed like it was buried like a time capsule or even more accurately repressed memories. It was something that he only ever smelled once before, which was in Muichiro. It made him contemplate whether or not to give Douma a chance. On one hand, he didn't want to upset Shinobu and Inosuke or have Douma not give a single care about this opportunity. On the other, this painful, buried scent cannot be ignored.
  Tanjiro sighed as he slowly approached the writhing demon. Both Akaza and Inosuke stepped to the side. Douma was struggling to get up when he looked at Tanjiro. "Douma..I'm going to give you a chance to change. It may take a while, but I gave you your humanity back so we can start again."
  Douma groaned softly. "I guess I could join you, but I can't make any promises." Douma laughed, playfully. With an irritated look, Tanjiro gripped  Douma's shoulder which made him wince. "This isn't just a game, Douma! If you even come close to hurting another human, then we will kill you again." His scarlet eyes were so intimidating that even Akaza and Inosuke looked uneasy.
  Douma quickly realized his mistake. "Okay, okay. I was only just kidding." Tanjiro shook his head. "This is no laughing matter." The young slayer sighed heavily as he went back to Shinobu. "I'm sorry, Miss Shinobu." Shinobu only smiled at him. "It's okay. I know. That you just wanted me back. Plus, it looks like you have him under control."
  Genya and Muichiro felt guilty that Shinobu had to deal with Douma being revived. They knew that it wasn't her or Tanjiro's fault, but they knew that it mustn't feel the greatest. So together they decided to make it even. The duo approached Tanjiro and told them their proposal.
  "Are you sure you want me to do that?" Tanjiro's voice was filled with concern. "Yes. We don't want Shinobu to feel alone." Muichiro said softly. "Yeah. This will probably be difficult, but maybe this might turn out better than we think." Genya smiled.
  Tanjiro returned the smile. "As long as you're okay with this." He sniffed the air and ran to a different part of the wreckage, Genya and Muichiro following behind him. Tanjiro reached a certain spot where the scent of bergamot was the strongest. He then performed the same magical process as he did for the others.
  This time the ashes formed the Uppermoon One demon, Kokushibo. Genya and Muichiro shuddered as they hid behind some of the wood rubble. The demon's six eyes slowly opened and he looked up to see Tanjiro. He stiffened up seemingly alarmed. "Are you..the new Demon King?" He spoke softly. Tanjiro nodded. "Yes, but I'm actually a half-demon." Kokushibo looked at the slayer's uniform. "I see.."
  "Why did you..bring me back?" Kokushibo seemed almost aggressive. "I shouldn't..be alive." Tanjiro felt some sympathy for the demon. The demon seemed to have a similar mindset to Akaza in this situation. Genya and Muichiro seemed weary of his words.
  "I'm here to give you a second chance. You were once human and I want to return your humanity back to you." Tanjiro explained softly. "I have nothing..to live for." Kokushibo nearly whispered. He then looked to the wreckage, seeing Genya and Muichiro..the descendant he killed.
  Truth be told, Kokushibo felt a great deal of regret when he sliced his descendant in two. That regret still haunts him now. As he looked at Muichiro, Kokushibo felt that guilt eating him alive. He wanted to make things right. Especially since someone is giving him that chance.
  "If you don't want to join us, I understand." Tanjiro said softly. "No..I'll do it." Kokushibo faced him again. "You do?" Tanjiro looked confused. "Yes...I have mistakes..to amend." Genya and Muichiro were skeptical. "Do you think he will?" Muichiro asked. "Doubt it." Genya growled.
  Tanjiro smiled warmly. "I wish you the best of luck then." The young slayer walked through the rubble back to where everyone else was. Kokushibo watched regretfully as Muichiro and Genya joined him. He turned to face the sky and sighed. "I'm sorry.."
  Rengoku walked up the broken pieces of wood to stand next to Tanjiro. "Do you want to travel to Kaikoma Mountain?" He asked, enthusiastically. "Not yet..I doubt that there would be enough room for all of the Moons back at the Butterfly Estate." Tanjiro clearly thought this through. "Smart decision, young Kamado." Rengoku knew exactly what he was going to do next.
  Tanjiro spilled more of his blood and used it to revive the master of the Infinity Castle. Nakime looked at Tanjiro and stiffened just like Kokushibo. "Hello, Miss." Tanjiro said politely. "You must be the new Demon King. My name is Nakime." Nakime spoke softly. She had a strong scent of fear coming from her. The damage that Muzan and Yushiro did when they killed her must've horribly scarred her.
  "It's alright. I'm not going to hurt you." Tanjiro gently spoke. Nakime shook her head. "What do you want from me?" She responded almost like a servant. "The only thing I want is for you to just give a home for the other Moons." Tanjiro smiled with warmth. Nakime looked around her to see the slayers and Moons. She was taken by surprise seeing that Tanjiro brought back some of the Moons.
  "As you wish, Master. I won't make the castle as confusing as I did before." Nakime turned back to him. "Thank you, Miss Nakime. There's also no need to call me Master." Tanjiro beamed with kindness, which was something that Nakime was not used to seeing. "Of course."
  Tanjiro stood up with a hearty smile and went to the other slayers. "Attention everyone! I'm currently going to Kaikoma Mountain to bring back the other Hashira." The other looked at each other and cheered. "Let's go!" Inosuke laughed excitedly. Nezuko and Rui smiled at the half-demon with new found hope.
  The group of slayers climbed the mountain while the Moons stayed behind in the rumble. They didn't want to make things more difficult for them then it already was. Luckily, it took roughly a few minutes to reach the two graves of the fallen Hashira. Everyone looked at each other, nodded, and started to dig.
  Using their claws, getting to the Hashira's caskets was rather easy. "Tanjiro! Gyomei's ready!" Shinobu trillsd, calling to him. Tanjiro walked over to his grave and peered into the casket. Gyomei's body was covered in bandages and scars. "I wished that there weren't so many deaths." Tanjiro said softly. "I know, Kamado. The good thing is that you're able to bring them back."
  Tanjiro nodded and smiled as he dripped blood into the Stone Hashira's maw. Gyomei's left leg grew back in a matter of seconds and various rocky spikes grew out of his arms and back. His skin even developed the patterns of cracked stone. Gyomei sat up and put a hand to his head. "Where am I?"
  Shinobu went down to him and hugged him tightly, sobbing. "Shinobu? Is that you?" Gyomei said softly. "Yes, it's me." She choked. Gyomei smiled and started to cry softly. "Are we reborn?" Shinobu nodded. "In a way. Tanjiro brought us back."
  "He did?" Gyomei turned his head upwards and smiled. "Well done, Kamado." Tanjiro bowed respectfully. "Thank you, Himejima." Another call came from the other grave. "We have Obanai and Mitsuri!" Rengoku yelled. Tanjiro couldn't help but smile as he walked to them.
  The dead couple remained in each other's arms even in death. "I hope that they'll be okay with us bringing them back." Nezuko said shyly. "I think they will. They deserve to be together." Tanjiro hums softly as  his blood drips into both of their maws.
  The scratch marks over Obanai's eyes heal to form scars. His mouth becomes more snake-like as various small fangs start to poke through. A slim, white snake tail formed and curled around his legs.
  On the other hand, Mitsuri's lost arms finally grow back. Bright pink wings with green feathers at the tips emerge from her back, making her look like an angel. Heart shaped marks developed all over her body. They seemed to resemble her demon slayer mark.
  Obanai was the one to open his eyes first. "Mitsuri?" His voice was soft and oddly warm. Mitsuri then opened her eyes as well. "Obi.." She smiled lovingly. It was only just then that she realized.."Wait! I have arms!" Mitsuri jumped up in excitement, causing the others to either yelp or chuckle.
  "Well, you have more than that." Obanai then also realized..."I can see!" He put up his clawed hands to make sure he wasn't dreaming. "What happened?" He asked, absolutely flabbergasted. "I believe we can explain that!" The couple turned their heads to see Rengoku and Tanjiro.
  "Rengoku!" Mitsuri immediately fumbled up and hugged him. Rengoku returned the hug along with a few tears. "Are we demons?" Obanai's voice sounded worried. "Not quite. You have your humanity and you don't need to eat humans." Rengoku reassured them. "If you say so." Obanai still didn't sound fully convinced.
  "Oooh! Everyone's going to be so happy when we get back!" Mitsuri chirped happily. "They will..they really will." Tanjiro smiled happily. Muichiro held Gyomei's haori close to his chest as both he and Genya approached the Stone Hashira-who was talking to Shinobu.
  "Here, Mister Himejima. You deserve this." Muichiro said softly. Gyomei turned to them and smiled. "Young Tokito...Young Shinazugawa.." He then warps his arms around both of them gently, tears rolling down his face. "I'm so glad that you're alive." They both nestled his head in the Stone Hashira's shoulders and hugged back.
  After a few minutes of chatting-and crying-they all decided to traverse down the mountain and head back to the Master's estate. They all felt so relieved and happy and they knew that their loved ones would feel the same.

  "So why did you summon us here?" Sanemi growled at Matsuemon. "Caw! Tanjiro wanted me to gather you all here! Caw!" The other crows cawed as well. Not only were Sanemi, Giyuu, and the crows there, but Kanao, Kaburamaru-who was around her neck-, and a few Kakushi were also sitting on the perch as well.
  "It must be pretty important if he wanted us to meet him here." Kanao hummed as she pet Kaburamaru. "I don't care what he wants us here for!" Sanemi roared. He swatted at Matsuemon, who flew out of his way. "We shouldn't be here. I don't understand why he wants us here or what the purpose of th-"
  Giyuu stood-almost jumped-up with surprise. "Sanemi..look." The Wind Hashira turned to face the sunset. There he saw all the previously dead slayers following behind the main trio. All the crows immediately took off to see their owners with tears in their eyes. Ginko circled around Muichiro before sitting on his shoulder and nuzzling his cheek.
  Kaburamaru slithered to Obanai, who lowered his arm so that the snake could climb up. "Shinobu!" Kanao sobbed as she ran to her adoptive sister. Shinobu's wings fluttered with happiness as the two reunited. Giyuu walked up to them with a smile on his face.
  "Hey, Kocho." His voice was soft and gentle. "You know, that's actually the first time I've seen you smile." Shinobu said jokingly. "Well..this is a pretty important occasion...I missed you." Giyuu started to cry. Shinobu dragged him into the hug. "I know I missed you too."
  Genya waved from the horizon. "Hey, Nemi!" Sanemi couldn't move. He just couldn't believe what he was seeing. "Genya.." Sanemi's eyes welled up with tears. His fell to his knees in utter disbelief. The few Kakushi stood up with wonder and hope in their eyes. One of the female ones took a step off the porch and took a deep breath.
  "The Hashira have come home!"
