Sorry If The Book Is Too Long. I Want To Kill All Of THe Demons In This Book So I Can Get Back To My Original Story.

All of the demon slayers formed a huge dragon formation. The leader of the Demon Slayer Corp walked to the front of the formation and said, "Since Akaza was defeated, Muzan the demon king will send all forces to kill the spies. Without their guidance, we will not be able to kill Makuta. They're our only hope. If we can stop Muzan, then the spies would be able to guide us through how to defeat Makuta. Do you understand?"

"Yes," replied all of the demon slayers including the Hashira.

We were walking through the Icy Plains, the place where Makuta and a masked good guy battled for the world. We were expecting to find Makuta's mask there, but because of the snow, we didn't find a single thing. We walked down the mountain, towards our base when something caught my attention. In the corner of the mountain stood a person, all alone in the mountain. The person gazed up and leapt towards us. Surprisingly, the person flew so far that he landed behind us. I turned around and realised he was Doma Upper 2. I took out my sword but I was a second too late.

Doma hammered the ice with his mighty fists that cracked the ice and separated us. Doma dashed toward me and used Barren Hanging Garden. Doma took out his fan and with a few slashes in the air, he completely froze my sword and I was injured severely. Iguro, Gyomei, Shinobu and all of the other spies came to the rescue. Doma used Rime - Water Lily Bodhisattva. Multiple giants made of ice attacked us. Gyomei used Arc of Justice and broke all of the ice giants. Shinagaziwa jumped from the sky and sliced Doma's neck. He flung Doma across the snow.

Doma jumped back towards us and used Frozen Lotus Vines. Gyomei took out the Mace (which was a mace attached to a chain) and shattered all of the ice vines. Doma ripped his fans to many pieces and threw them all at us. They immediately became ice and headed straight towards Carter. Iguro sliced the fans in pieces and vanished. He appeared behind Doma and managed to slice off his arm. Doma regenerated and waited for his chance to attack. Shinagaziwa came jumping from his blind spot and sliced Doma's neck. He tried to pull his sword out, but it wouldn't budge.

Doma's arm became a sharp icicle and attempted to stab Shinagaziwa. I zoomed forward and sliced Doma's arm in half. Carter and Gyomei used a combined attack, Volcanic Spin. Carter's sword turned bright red and blinded Doma. Gyomei took out his Mace and hammered it onto Doma, crushing his head. Then, Iguro slammed his sword down onto Doma's neck and managed to sever it. Suddenly, Kokushibo fell from the sky and landed in the middle of the battlefield. Kanao used Honourable Shadow plum but it was deflected back at her. 

Gyomei used Stone Skin to block the attack but he got injured. Tanjiro jumped up and used Waterfall Basin but he couldn’t hit him because he was too slow. Shinagaziwa used Dust Whirlwind Cutter and sliced Kokushibo’s guts opened but Kokushibo’s sword sliced Shinagaziwa’s cheeks. Shinagaziwa’s cheeks immediately healed and a windmill symbol appeared. It was the legendary Demon Slayer Mark. The mark would boost all of your abilities to 100% but it only lasts till the end of the battle. Shinagaziwa charged forward and attempted to sever Kokushibo’s neck. 

Kokushibo sent a moon sickle at Shinagaziwa but because of his Demon Slayer Mark, he was able to dodge it. When Kokushibo was within striking distance, Shinagaziwa used Claw Purifying Wind. He made a few marks on Kokushibo but it regenerated immediately. Kokushibo slammed his sword into the ground, creating a large earthquake. When we were distracted, Kokushibo used Dark Moon and sliced both of Gyomei’s arms off. Gyomei’s arms immediately regenerated as he received the Demon Slayer Mark.

Meanwhile, Zenitsu Agatsuma was fighting Kaigaku Upper Five. They both knew Thunder Breathing but the only difference was that Kaigaku could regenerate. Zenitsu took out his sword and used Thunder Breathing First Form Thunder Clap and Flash Six-fold. Zenitsu dashed across the room, creating lightning on his sword. He appeared behind Kaigaku and sliced both of his arms off. Kaigaku jumped back and used Thunder Breathing Second Form Rice Spirit.

Kaigaku threw his sword at Zenitsu but Zenitsu dodged it. Zenitsu jumped up and used Distant Thunder. Zenitsu used sound and speed to create many swords that flew toward Kaigaku while Zenitsu went for Kaigaku’s neck behind him. Kaigaku immediately spun around and used Rumble and Flash. Zenitsu dodged it and threw a blow at Kaigaku’s neck. Kaigaku used his sword and blocked it. Kaigaku kicked Zenitsu on the head and sent him flying. Zenitsu recovered and used Thunder Clap and Flash Eight-Fold.

Zenitsu appeared behind Kaigaku, threw a blow and disappeared. He did the same attack for exactly nine times before he got hit by Kaigaku. Zenitsu knew he couldn’t beat him so he used his last attack, God Speed. God Speed enabled Zenitsu to use different attacks randomly at a surprising speed. First, Zenitsu severed Kaigaku’s legs. Then, Zenitsu damaged Kaigaku’s chest. Lastly, Zenitsu sliced off Kaigaku’s arms. Zenitsu was about to make the last blow at his neck when Kaigaku caught his sword. 

Zenitsu jumped back and prepared himself to use Thunder Clap and Flash. Zenitsu realized that Kaigaku was about to use the same attack. Zenitsu charged forward but instead of using Thunder Clap and Flash he used Thunder Clap and Flash Six-fold. Kaigaku went straight forward but Zenitsu dodged the attack and sliced his neck off from the back.

Tengen, Nezuko, Tanjiro, Inosuke VS Daki & Gyutaro

Nezuko is a demon but because she was hypnotized, she fought for good.

Nezuko used exploding blood to stop Gyutaro from attacking. Daki was about to use Nine Obi Slash when Tengen Uzui used Roar. Daki was paralyzed for a few seconds. Tanjiro used Sunflower Thrust on Daki but Daki dodged it. Tengen used Constant Rounding Slashes against Gyutaro so Gyutaro couldn’t use any attacks. Inosuke came charging at Gyutaro from the back and managed to slice off Gyutaro’s neck. Gyutaro’s body stabbed Inosuke and Tanjiro but turned to ash before he could stab Tengen and Nezuko.

Tengen used his last attack which was String Performance. That attack provided Nezuko an opportunity to slice off Daki’s neck. Daki saw Nezuko coming but he wasn’t prepared for Tengen. Daki used Nine Obi Slash and injured Nezuko but Tengen Uzui used String Performance and sliced off Daki’s neck.

Muichiro & Mitsuri VS Nakime

Muichiro used Black Mountain Mist to blind Nakime but it was no use. Mitsuri charged from behind Nakime and used Shivers of First Love.

Nakime was pushed backwards but evaded Muichiro’s attacks. Nakime took out his guitar and played a few songs. Suddenly, Muichiro got slashed. They realized that the guitar Nakime uses generates invisible slashes. Muichiro and Mitsuri tried to keep up with the attacks but they were too random. Tengen suddenly appeared behinnd Nakime and used his swords to slice the guitar. Nakime sent a slash towards Tengen but he dodged it because he was able to hear where it came from. 

Tengen used Constant Rounding Slash to block all of the slashes that Nakime made, creating an opportunity for Mitsuri to sever Nakime’s neck. Mitsuri charged towards Nakime and used Cat Love Shower. Nakime’s head slid off her neck and fell to the floor. His guitar fell to the floor and shattered.

Spies, Shinagaziwa, Gyomei, Iguro and Shinobu VS Kokushibo

Kokushibo used Dark Moon to block Shinagaziwa's attacks. Gyomei threw his Mace at Kokushibo but Kokushibo threw it back.

Gyomei caught the Mace and swung it at Kokushibo. Kokushibo used Pearl Flower Moongazing to stop it. Gyomei then swung his Mace upwards and it bashed Kokushibo on the chin. Shinobu used True Flutter to stop Kokushibo from attacking but Kokushibo dodged it and used Evening Palace to attack Shinobu. Iguro pulled Shinobu backwards and used Coil Choke to block his attack. Iguro then used Slithering Snake. Kokushibo didn't see the attack coming and got damaged. Gyomei used Serpentine Bipolar and destroyed Kokushibo's sword.
