Author-san here! This is my second story! Of course, I might imply little pairings or just flatout tell you. No kokudou -maybe-. Douma gets jelly easily because sometimes when his friends are hanging out with someone new, trust issues and all, he'll think that the guy/girl that they are hanging out with will steal them. I'm gonna die. Well, anything for you all. I've got lots to do, and I'm going to post my stories on AO3 soon. I'm waiting for the account activation email. So... IDK! So, what I want to start with, I want to start in the prologue with the backstory I have made with Douma, Akaza, Muzan, Yoriichi, and Kokushibo, these people have been included because the ladder -minus Muzan- were born in the Sengoku Period. So, enough yapping from me, LET'S START!


What if... there were halflings, what some characters were siblings and born to different family... What if the demon slayers were betrayed... What if some characters were evil... What if there were betrayels... What if some characters were over powered... What happens when Muzan comes across something he wasn't supposed to... Let's explore this glorious parody...

PROLOGUE

Bubbles were going to the top in the test tube, a pale hand reached out picking it up and raising it to eye level. The owner of the hand has a lean muscular build along with unnaturally pale skin complexion. He has curly black hair and sharp, almond-shaped eyes. His irises are cat-like in appearance and are of a plum red color. His nails were sharp and blue in color. He's wearing an embroidered black tuxedo with a white tie over his black dress shirt and white dress pants. He also wore black loafers. It was Muzan Kibutsuji. He was experimenting with his blood when he came across something... new. This made Muzan tilt his head, eyes narrowed, confused. "What the hell?" Muzan questioned, as he studied closer he realized what he could give himself...

...

An heir

About five years later

"Hetatsuri, please stop running around! Ume, please come back and get ready!" Muzan shouted lightly, running after Hetatsuri. Hetatsuri had platinum blonde or white hair and his eyes looked to be an array of rainbow pastel tones that fade into one another as they circle his irises. He was giggling and running around before bumping into Ume, knocking them both down. Ume, in contrast to his name was a little boy of four years, while Hetatsuri was five. Ume had black hair that fluffied out around his head, with pale blue eyes with unusually-colored light pink eyelashes. "Those two are so very troublesome." Complained a female, causing Muzan to look up, "Just like you, Akuma. Beside they both are young." Muzan said looking toward Akuma, who had black hair and crimson eyes. After the two boys got ready, they were walking, "Why do we have to be dressed in such a fancy way, Tou-san" Ume complained, as he preferred to be in simple clothes. "We need to presentable to the head of Tsugikuni clan." Muzan responded looking towards his boys, who were in fancy kimonos, Ume in a light pale blue kimono while Hetatsuri was in a red kimono. Muzan was in a orange kimono with the black coat and the crown.

After some walking they met up with the Tsugikunis, "Tatsuri, ume go off to the side and play." Muzan instructed. While Muzan, Akuma, Akeno and Homura discussed about alliances and friendships, while Hetatsuri and Ume were running around trying to catch each other, when Hetatsuri noticed two boys, they both have black hair, while the older one has dim purple irises. He was wearing a white kimono with black yukata pants. The other was had maroon eyes and untied hair that reached his shoulders. He was wearing a red haori with a pale orange obi belt. "Do you want to join us?" Hetatsuri asked happily, Which flustered the two boys as his personality was so bouncy and blubbly that was he was often confused for a girl. "I guess..." "What's your names?" Hetatsuri asked, tilting his head to the side lightly. "Michikatsu and my younger twin is Yoriichi." Michikatsu said flushered by the sudden question.

"Here follow me," Hetatsuri said going into the forest, leading them to a mini obstacle course. "We set this up ourselves." Ume said, answering the unspoken question, "We want to be strong to protect our father, he isn't like other fathers, he actually cares." Hetatsuri said turning to them, "Would you like to go through?" Hetatsuri said as he tossed his coat, accessories, and shoes to the side before starting. He started by jumping across logs before walking across a thin rope while keeping balance, he also began to climb a tall tree, while looking down "Hey, Ume, toss me that rope!" Ume nodded, grabbing the rope and throwing it up for Hetatsuri to catch. Hetatsuri caught it and created a knot and threw it, cause it to wrap around another trees branch. "Do you see the pile of leaves mixed with mud?" He asked the Tsugikuni twins, half expecting an answer.

Yoriichi nodded, while Michikatsu was trying to figure out what he was going to do. Hetatsuri jumped and used the rope to swing himself over the muddy leaf pile, then he let go, the rope grabbed at his ankle which made Hetatsuri falter in his descent and that cause him to falling faster and land on his arm "Oww, err- Ta da!" Hetatsuri shouted standing up hastely. Yoriichi seemed like he had a heart attack, dashing forward, lightly taking Hetatsuri's injured arm, and started to wrap it in bandages. "I'm fine, I swear," Hetatsuri said, not wanting the bandages to be wasted on him. "I don't believe it," Michikatsu stated boldly "You do realize that if you landed on you head, it's bye bye Hetatsuri." Michikatsu said continuing "Besides we're friends now, its normal for us to worry." Michikatsu said smiling.

After that, they ran around play with each other, before coming up with an idea, they surrounded a cherry blossom tree and each were holding ribbons, Hetatsuri had pale blue and red, Ume had pink and white, Michikatsu had purple and black, and Yoriichi has orange and marron. They ran around the tree wrapping the bark in ribbon, then they made it so they could hide things in the tree, opening only with their handprints, so they desided that they were going to store cash and valuables in the tree, for a future, together.

"Ume! Hetatsuri! Time to go!" Muzan called out, Hetatsuri hurried "Quickly, a promise, that we stay loyal to each other!" The others nodded and began creating a promise that would change their life's "That we never forget each other!" Ume chirped happily, "That we welcome each other with open arms!" Michikatsu added, "And we always support each other," Yoriichi finished thoughtfully, them all agreeing, they ran to their parent and went home

When Ume is nine and Hetatsuri is ten

"Are you ready to leave Akaza?" Hetatsuri questioned his brother, they had began to call each other by nicknames. "I'm ready, I just hope we have enough cash, Douma..." Akaza admitted, reluctent. "You don't want to leave them, Michi and Yorii, Koyuki and her grave?" Akaza nodded, the wound from Koyuki's death still sore and bleeding, "What about the promise?" Douma smiled tenderly, understanding him, "We'll leave them a letter, okay?" Douma said, closing his eyes as he finished putting the clothes in the bags. "I guess... I just hope they will be alright without us..." Akaza said expressing concern.

After they finished packing, they wrote their letters and placed them on the doorstep, four letters, two for each, packing with a gift, running away with teary eyes, into the cold night, the door opened, Michikatsu peeked out seeing the letters, Yoriichi came over rubbing his eyes, "What's that?" Yoriichi questioned, "I'm not sure, Maybe it's from Hetatsuri and Ume!" Michikatsu replied, handing Yoriichi the two writing under his name.

Dear Michi, I hope your doing well, I'm here to tell you that sadly, we might never see each other again. I hope you can forgive me for breaking our promise, but we needed to leave that dreaded place. I hope that in time, if we find each other again, you could open your heart to me again.

The reason we had to leave was because that cult... did terrible things, to me, to Ume, to my family, I had to leave. They would enter my room, and pin me to the bed and... rape me... when they didn't hear what they wanted, they grabbed me by my ear and dragged me in a different room and beat me bloodly. I took it all, Ume shouldn't have had to deal with this. I never told you because of someone I met in the cult, a young girl wanted to be my friend, but she manipulated me, made me side against you, made me buy her expensive thing, made me treat her like a princess. It drove my insane, I remember blacking out then waking up, she was dead and I was bloodied.

I couldn't trust anyone properly again, I hated myself, I even cut at my skin with glass and with the same knife that killed my father. I faced everything head on. I'll be honest, the smiling you see me do was fake... I lost being able to feel, I couldn't be happy, angry, scared, upset, or feel love... I've attempted THAT multiple times. I just hope that you can find it in your heart to understand what I have done, I know I leave behind the future we all dreampt of together and it kills me but I needed to leave, the scars, the crying, the hopelessness, the unhappiness, and the feeling of it being all my fault.

My gift to leave you was the haori, purple and black with a hexagon pattern. I know I was being selfish leaving, but if I go, I want to leave something to you. I hope to see you again in the future

-Yours eternally, Hetatsuri or Douma

Michikatsu was teary eyes, as Yoriichi read the letter left to him from Hetatsuri, holding a red haori. Holding back tears, they began to read Ume's letter...

Dear Michikatsu or Kokushibo, Hello. If you read Douma's letter first, then you know we're leaving. I do hope you can forgive us for just abandoning you two... But we ready had to leave that discusting place. We needed the hope.

We left the cult because Douma could't handle what they force him into. At night I hear screaming, crying, begging, and... when I walkout of the room the blood plastered on the walls, screaming echoing on the wall. It didn't do us any good that Douma was betrayed by that female. It drove us apart and caused trust issues... I'm well aware that Douma took abuse to keep me safe... I told him not to but he doesn't listen, apparently I'm more important then his mental health. I hate that Douma gets manlipulated because of his nice heart.

I'm losing trust in people and since Koyuki died, trust is harder for me to show. I hate it. But please do understand, we do want to stay but it's not a choice we have anymore. I just hope you both decide to grow into amazing people someday... just make sure to use your strength to help rather then harm, please make sure to grow and stay close... We both don't you either of you to fall apart, like we have. So try to stay together and help just as you have helped us.

My gift to you is this Nichrin blade that I have been given from a dying Slayer. I know that we're being selfish and going away, but if we go, we want to leave something to you both. I hope to you again in the future

-Your Snowflaked friend, Ume or Akaza

That was the breaking point, Michikatsu was tearing up while Yoriichi started to cry out loud. They both collapsed into fits of tears, sniffling and coughing, they went back inside holding the gift of their friends right above their hearts.

When Akaza is fourteen and Douma is fifthteen

Douma shrieked as the demon ran foward, Douma, now panicking, slammed a hard metal tray into the head of the demon. "AKAZA!" he shouted, Akaza ran forward an engaged in hand-to-hand combat, keeping up with each other destoring the street. They exchanged blows, creating craters around them. A quick swipe and managed to slash at Akaza's leg, creating a gash.

A sweet scent entered the air, it was Akaza's marechi blood. Akaza gasped in pain, lashing out one last attack to blow the demon back. Douma ran over and picked Akaza up bridal style and dashed away. They ran to their small house, Douma grabbed a firstaid kit, tearing at the rim of his shirt to wrap it around Akaza's leg. Picking up Akaza and bringing him into a closet.

Swiftly closing the door, Douma placed his hand over Akaza's mouth. Sweating and nervous, they stayed in the closet.

Screaming and begs to live echoed everywhere, tears entered Douma's eyes. "Please... Help us... Save Ume first... Make he lives..." Douma pray-begged in his mind as he wrapped his free arm around Akaza. This wasn't why they left, to suffer as a demon ate them.

The demon picked up their scent and started to walk towards the closet, Douma's throat constricted while Akaza began to whimper and go limp. The demon gave a surprised squeek as someone with long hair tied in a ponytail ran over striking with his sword removing the demons limbs, while a secondary person with a similar hairstyle came and decapatied the demon. The demon fell and turned to ash.

"Go check that closet." The one with the red haori said, as the one with the purple and black hexagon haori went over and tried opening the closet. He sweat dropped, "Brother, this closet is aged and the wood is slightly warped." The red one sighed, "I'm coming." He said, as the purple one stood watch, the red one pulled at the closet, before finally opening it. "Finally, you can come out now, the demon is dead-" He cut himself off, recognizing them, tears started to track down his face. He was a tall man with a lean muscular build, fair skin, maroon eyes, and long spiky hair with red tips that he kept in a ponytail. He was slightly more slender, had shorter bangs, and wavier hair. He wore a red haori over a very pale orange-colored nagagi kimono with a black umanori styled yukata pants, a pair of zori with red straps and white tabi socks, with a Nichrin sword at the left side of his waist, He also wore hanafunda earring.

"Y-Yoriichi?" Douma chokingly questions, tears flooded down his face. "What's taking so long-" The purple started before stopping. He was a tall man of muscular build with a pale complexion, he wears a purple-and-black hexagonal-patterned nagagi kimono and black umanori-styled hakama pants tied with a white uwa-obi. He also also has red markings resembling flames on the top left side of his forehead and the bottom right of his chin. He also has a nichrin sword on the left side of his waist. "Oh God, Hetatsuri... Ume..." He said in horror, his hand raising and began hovering over his mouth.

Yoriichi broke down crying, then he leaned forward and wrapped his arms around Douma and Akaza. "w-we thought y-you both d-died..." Yoriichi tried to say but kept stuttering due to hiccups. Michikatsu soon broke down to, and wrapped his arms around them. Douma openly cried for the first time, burying his face into Michikatsu, he still held Akaza close, Yoriichi was there and hugged Douma from behind.

No one said much more, they just cried, releasing the harbored emotions that made them ache.

When Akaza is seventeen and Douma is eighteen

"We have two new hashira." Hideyoshi Ubuyashiki stated shocking all but two hashira. "May I ask who it is" Yuri Hanae, the flower hashira asked. The hashira are as following, Moon Hashira- Michikatsu Tsugikuni, Wind Hashira- Takeshi Hayate, Flame Hashira- Enjuro Rengoku, Sun Hashira- Yoriichi Tsugikuni, Thunder Hashira- Shin Kaminari, Water Hashira- Yusuke Mizuhara, Stone Hashira- Kazuyoshi Iwamoto, Flower Hashira- Yuri Hanae, Phoenix Hashira- Suzaku Otori, Mist Hashira- Mokaro Kuze, Shadow Hashira- Kagero Uzui, Light Hashira- Mitsutoshi Amamiya.

"I don't know much about them, beside that facts, they were trained under Yoriichi and Michikatsu, they created their own breathing styles, and I know their nicknames." Takeshi grunted "That's not enough to trust them..." He grumbled. Yoriichi shook his head, Michikatsu tapped Yoriichi doing a hand sign signaling they are here already, which made Yoriichi nod.

"Aww, so are we not allowed here anymore Oyakata-sama?" A voice called playfully, "Discusting, aren't they brother?" A secondary voice called. The first voice has white hair and rainbowy eyes, he wore black yukata pants, red nagagi kimono with a black dripping pattern near the neck, he wore a light blue kimono that had snowflakes and icicles on it. He has a sun and moon hair pin, with his hair drawn back with a hairtie that resembles a snowflake. "Douma, Hail Hashira!" Douma exclaimed happily.

The secondary person had black hair, blue eyes and pink eyelashes. He wore similar black yukata pants, however he wore a pale blue nagagi kimono with a pink vest with blue markings. He had a snowflake hairpin. "Akaza, Tempest Hashira." Akaza said cooly.

"These are the new Hashira, so flashy!" Kagero said, "Beautiful even!" Douma giggled as he and Akaza went and bowed right before the master, they bowed deeply, showing respect. "Please rise and place yourselfs among the hashira." Hideyoshi said gently, Douma and Akaza nodded before sitting next to Yoriichi and Michikatsu, who never let anyone sit next to them. Akaza took his place next to Yoriichi, while Douma more teasingly, sat on Michikatsu's lap. Michikatsu turned away flustered, Douma giggled before gently cooing, "Am I making you uncomfortable?" He said his expression changing to be more questioning and it worked.

Michikatsu gaped "N-no! I-I was just staring at the sun!" He said quickly covering himself with an excuse, Douma giggled as he wrapped some of Michikatsu's hair around his finger, "I could never get you so flustered Koku," Douma said gently. "KOKU- Koku..." The other hashira questioned.

After getting formal and bowing before the master, "Mind telling us what your weak asses can do?" Takeshi said, angry at Akaza's previous comment.

"No" Akaza said simply.

"WHAT!" Takeshi Shouted

It was going to be a long day

Two months later

They were walking through a forest, when they heard rustling coming from a bush. A male came crashing out, crashing into Yoriichi. When Yoriichi pushed himself up, he relized he was right above the guy. He has curly black hair and pink almond-shaped eyes. They hurried to stand and bow out an apology. "My name is Yoriichi" Yoriichi said after getting over being flustered. "I'm Tsukihiko." Tsukihiko said, happy that he didn't mind.

"Let's head over to that sweets store," Douma said, slightly drooling as he thought about the sugary sweets. Akaza laughed, Yoriichi smiled, Michikatsu sighed, while Tsukihiko nervously figited.

When Akaza is nineteen and Douma is going onto twenty

Akaza was walking in the forest, not minding his business. When a demon jumped out at him, which was unexpected. Fist met fist, they clashed. Akaza threw a left hook, hoping to land a blow, the demon in turn dodged and threw a punch to Akaza's gut, hitting him. Akaza gasped out, throwing up fluids, quickly dropping and swiping out with his leg, knocking the demon down.

Their battle raged on, destoring the area around them. "AKAZA!" Douma's voice rang through causing Akaza to lose his focus, and then he went cold

...

"AKAZA!"

The demons hand went through his chest, piercing through. Blood splurged from his mouth as he body went weak, he then collapsed. Coughing horribly, blood pooling around his body. The demon grinned wickedly, squeezing at Akaza's heart, before crushing it.

Akaza screamed as the pain flaired though his body, soon his body began to convulse, as he blacked out.

"BROTHER! NO!"

Tendrils exploded from the ground, and threw a subdued Douma, Yoriichi, and Michikatsu deep into the forest. Tsukihiko roared, bringing the demon to her knees. "Kimino, what have you done..." Tsukihiko said as he bit into his palm, dropping his blood into Akaza's wound. "Master Muzan, why do you care? It's a just a human." Kimino said cockly, thinking that Muzan would agree.

"That was my son..." Muzan said, already starting to cry. He had his hand on Akaza's face.

Akaza was convulsing and going pale. The blue marking spread across his skin and his eyes changed as his hair turned pink, and he started to get fangs. Soon he started to growl and drool. "You fail me Kimino." Muzan said as he blew up her head.

On the night of Douma's twentyith birthday

Douma was sleeping. Soon the ground rumbled, shaking Douma awake. "what..." He said rubbing his eyes. The ground rumbled again, this time Douma sensed demons in his home. Shooting up, he panicked a bit, grabbing his sword. He was in a red shirt with the same black dripping pattern on the shoulder and loose white pants with black socks.

Running down stairs, he slayed demons, running on end. Soon he saw the main area where Yoriichi and Michikatsu were fighting demon, Douma tripped and fell to Muzan's feet. "Forgive me son..." Muzan thought as he reached out, grabbing Douma's head and began to crush it. DOuma screamed as the pain in his head flared.

Michikatsu's eyes widen as he grit his teeth, and got reckless. A demon striked at Michikatsu but he was slow to dodge, his left arm went flying away and he also loft his right foot. Grunting, he continued, "M-Michi" Douma weakly said. Michikatsu only got more moved, but before he could get to Douma, his head was crushed.

Muzan threw him away. Michikatsu began to hyperventilating as Douma was thrown to the side to bleed out. He let out a battle cry and dashed forward, another strike and he lost his sight, continuing forward he was striked, being slashed across his chest. He was flung away and landed next to Douma.

Them both bleeding heavily, reached out for each other and held the others hand, going to never let go, they closed their eyes. Muzan smiled and tendrils come out of his back and hit them on the neck, injecting them with blood.

Soon the building exploded sending them away, Yoriichi picked up Michikatsu and ran away.

Douma woke up before the sun rose, he was hungry. He looked over to his side, a chest was there. He went over to it and opened it, pulling out dangling lightning bolt earrings. He put them on, grabbing a chain ring, a necklace with a cherry blossom charm, a light blue blanket, and pulled out a dark cloak. He tied the blacket around his neck to ack as a bandana, putting on the rest of the assesseries, pulling on the cloak.

He ran around destroying villages, soon he saw Michikatsu or now known as Kokushibo. He was about to go to him before realizing he had a wife and two kids. Fury burned deep inside Douma as he went around and destoried the village. After his kids grew up, Douma had finally located her. "I personally have no grudge against you, Haruki. So I'll make this quick and painless for you." Douma said, flexing his claws.

"That's I all I ask." Haruki said.

After Douma finished her off, Yoriichi had come across him, seeing him charge at the people. When Douma realized who it was, he cried into Yoriichi. He was soon gagged and traveled with Yoriichi.

At the Oyakata mansion...

"My apologies, but you have to leave the Demon Slayer Corps, Yoriichi." Aoki said, "it's best if you leave that... demon... to us. He will be slayed." Yoriichi was hesitant at first, but soon nodded, think Douma would be happier in heaven with his brother.

The door slid open and standing there was Douma, he looked sad as he reached up and removed his mussle.

"I trusted you all, I was one of your brothers-in-arms... and you just leave me... for dead..." He shook his head, "I deeply apologize for what I'm about to do, Aoki, but I do what I must." he said as he shot forward, claws digging into Aoki's shoulders. "My first to feast on... not sure if I'm happy, I just wish you didn't condem me to death, it too late for what-ifs now."

Douma opened his mouth and bit down heavily on Aoki throat, eating at the flesh as blood dripped down. Douma had move far to quickly for them to stop him, so when Aoki's lifeless body fell to the ground, Douma was in the yard, clothes bloodied. They tried to catch him but they failed horroribly, he was just to quick. After all he was the fastest hashira.

"Now, I bid you all farewell." Douma said as he dashed away. The other hashira ran after him in attempts to slay him, "This is all you fault, Yoriichi." Takeshi said, sword raised high, going to strike in attempts to kill Yoriichi.

Yoriichi's eyes narrowed as he unseathed his sword and deflected the strike. Yoriichi struck quickly, preventing Takeshi from blocking. Yoriichi had cut Takeshi arm off.

With his arm gone, Takeshi was forced to use his left hand. Yoriichi, who was faster, kicked him in the back of the knees and forced him down. Takeshi's was lying on the ground, Yoriichi came and stood over him and grabbed him by his hair and placed his sword up against his neck. "You all know damn well Douma would have never attacked if you hadn't condemned him to an eternity in hell." Yoriichi gave an unamused snort and let go of Takeshi. Yoriichi turned away walked away.

When Yoriichi and Kokushibo met again sixty years later...

Kokushibo walked calmly through the open path, unaware of the blind eyes that stared at him. "Brother." Upon hearing this Kokushibo turned around and saw Yoriichi, except now old. "Yoriichi." Kokushibo said cooly, "This is heartbreaking, brother." Yoriichi said as he started to cry. "Prepare brother" Yoriichi called as he took his stance and surged forward, slicing Kokushibo's neck, but not a killing blow.

This angered Kokushibo further. He unsheathed his sword thinking, "I must be cautious, or the next blow could very well be my downfall." But the next attack never came, which confused Kokushibo. When he looked at Yoriichi, who's head was down, shoulders slumped, his blade in the ground, and moving and inch.

Yoriichi had passed away right then and there.

This only made Kokushibo angrier, out of spite, he swung his sword and cut Yoriichi's dead body in half. When he sheathed his sword, he noticed the wooden flute he carved for Yoriichi when they were kids. Seeing this, Kokushibo realized that Yoriichi saw him as a higher figure, this caused all three eyes on his left side to start crying.

Kokushibo rubbed the back of his hand over his eyes, when he opened his eyes he saw a cloaked Douma. "Stop." This made Douma freeze. "Who are you?" Kokushibo asked, his hand resting on the sheath. Douma turned around. Kokushibo noted the cloaked demon's eyes were giving off a strange glow, while his eyes flashed different colors like an LED light strip.

"What's it to you?" Douma quickly snapped back which made Kokushibo flinch slightly. "Douma?" Kokushibo questioned, only Douma had dared to snap at Kokushibo like that back then. "Congrats, you found me." Douma said, removing the hood.

Kokushibo flinched once again, after hearing the heavy sarcasm lacy in Douma's voice. Kokushibo opened his mouth to speak but nothing came out. "Stop gaping like a damn fish." Douma said, he words like a whip. "If we're done here, I'm gonna go bury Yoriichi next to his unborn daughter." Douma said turning away, "Oh, and here." he continued, throwing the wooden flute over his shoulder.

Kokushibo rushed and caught it. He followed Douma and assisted in the burial.

Later, Douma is now at Sumiyoshi's place...

Douma snuck in and walked 'till he saw the slumbering Sumiyoshi, deciding to leave a letter and his hair pieces. When Sumiyoshi woke up, he saw the letter. When he picked it up, a snowflake hair tie, and two hair pins, a Sun and Moon, fell. He picked them up and read the letter.

Dear Sumiyoshi Kamado, I hope you're doing well.

The hair accessories I want you to keep. I'm also writing this letter to let you know that Yoriichi Tsugikuni had passed away. I have already buried him next to the graves of his friends, unborn daughter, and older brother. I'm very sure that he would have want you to keep living life to it's fullest. I'm writing to hopefully allow Yoriichi to rest peacefully despite not having said goodbye. From the bottom of his heart and mine, we say goodbye and wish you prosperity.

Respectfully, Douma.

When Sumiyoshi finished reading the letter, several tears fell down his face as he grieved the loss of a friend and someone who fought and protected him and his family.

Two hundred years passed and its time for the placement blood battles...

Douma had been summoned like plenty of others, he first bowed before Muzan than went to the side to wait for his turn in battle.

When his time came he stood up and walked over, he was met with Akaza, shock written on both of their faces. Akaza shook his head and raised his hand, "I refused to fight my brother, even if you tempted me I wouldn't fight." He said as he limped to the side. Kokushibo came over, rather he wanted to fight. "Finally, someone I want to fight." Douma said, growling.

Muzan stood watching, "Begin."

Ice exploded everywhere, Douma had his golden war fan raised, "Chiri Renge" Douma said generating the projectials. Kokushibo unsheathed his sword, and readyied himself, "Ni no Kata, Shuka no Rogetsu" Kokushibo said as he created three slashes. Blows like this continued, but soon enough, only Douma knew he was slowing down. "Kessho no Miko" Douma cried, creating five mini ice copies.

Douma scruied away to find his sword and bow, which they other demons thought he was running away. When Douma found the loose board, he pryied at it before kicking his heel down and destroyed it, pulling out the weapon he quickly strapped them on. When he came back, three of the mini Douma were destroyed, the remaining two ran and hid behind Douma's leg.

This made Douma furious, "Who are you to destory my ice children?!" Kokushibo shrugged, "They were in the way." This infuriated Douma further, drawing his sword, he charged forward, "Hachi no Kata, Kurisutaru Kasukedo" Douma said as he swung at Kokushibo, he managed to cut Kokushibo's face, just barely missing the lower eye. Frostbite started to claw at Kokushibo's face but the blows rained down on him like an icy waterfall. Kokushibo struck forward, swinging his sword, he modified his sword. "Ku no Kata, Kudarizuki - Renmen" Kokushibo cried, swinging his sword.

Douma knew at this rate, he was going to lose, he was going to have to use Sun Breathing. But, he needed energy, "Muhyo - Suiren Bosatsu", ice exploded up, creating a giant ice Buddha, Douma sat on the shoulder and began meditating to recover energy. Kokushibo was starting to sweat, swinging his sword, "Ju Shi no Kata, Kyohen - Tenman Sengetsu." Kokushibo cried, using the form multiple times over.

Soon Douma stood up again, when he opened his eyes, blood started to enter his eyes, he had popped the veins in his eyes. Inhaling, "Ku no Kata, Nichiun no Ryu Kaburimai" Douma called out, swinging his sword in a livid movement, the flames that came off his sword took the shape and form of a dragon. Douma moved swiftly and left no time for Kokushibo to protect himself.

When Douma finish the form, blood started to pool from his mouth. Kokushibo was standing shocked, "No one could perform Sun Breathing... why was Douma able to?" Douma turned around and looked Kokushibo in the eyes. "I've waited for the moment that I would defeat you in a battle." Douma said, his face betraying no emotion. Douma jumped into the air and began to preform the thirteenth form of Sun Breathing.

Kokushibo's eye's widen known that could very well be the end of him, "Hachi no Kata, Getsuryu Rinbi" Kokushibo shouted, panicking, swinging his sword. Dust rose and covered them, however two tendril swept through and the dust was gone. The two sheathed their swords, before blood surged out from their collars, they both collapsed.

Akaza dashed over to Douma and lifted him up and bit, Douma's eyes were glittering and glowing, his eyes sadden and pained. "Did... I do good?" Douma asked before coughing up blood. Muzan stood nearby, his expression hardened but sad, "You did perfectly, my son..." Muzan said softly, gently reaching out to place his hand on Douma's face, before closing Douma's eyes. "Rest," Muzan had to close his eyes to prevent himself from crying, "Daddy... keep away the monsters..." Muzan's eyes snapped open and he turned to Douma, who had shrunk down in size, who was know the size of a toddler.

Inner Muzan broke down and started crying out loud. While outer Muzan stayed strong and didn't cry, he took Douma in his arms and cradled him. Kokushibo had dragged himself over and was watching. Akaza helped him up, while Muzan stood up and cradled Douma. "The placements have been decided. Uppermoon six- Daki and Gyutaro, Uppermoon five- Gyokko, Uppermoon four- Hantengu and others, Uppermoon three- Akaza, Uppermoon two- Douma, and Uppermoon one- Kokushibo."

Muzan took a breath then turned over to Nakime, "Send them to where they were before the battles. Take me and uppermoons one through three to an infurmary like room." Nakime nodded and strummed her biwa.
