As Kokushibou tried to regenerate from the attack, he was shocked as multiple flames in the shape of a dragon were launched straight at him; as he sliced them away, they exploded on impact as Kokushibou avoided them by jumping back as Neo laughed.
"Upper Moon 1 Kokushibo being afraid! hahahahaha, what's wrong? Michikatsu Tsugikuni, I thought you were stronger!"
He had a wide grin as 8 eyes sprouted out of his head as they had lizard-like features. He then sliced the smoke in half, only for Kokushibou to be at his face and slice at his throat, only for it to be blocked by the hilt of his blade as his grin got wider as the hilt and blade touching made a thud noise as he used his other blade to drive it into his liver. Kokushibou saw the attack coming as he stomped his katana down on the ground, ripping out Neo's arm. Neo was shocked by the sheer strength as Kokushibou launched a 5th form at him as his cheeks and eyes got sliced away alongside his arms as he backed up and chuckled as Kokushibou smiled.
"Upper rank 2 Neo Garcia, you're nothing but a pussy and a cheap fucking knockoff!"
Kokushibou spoke out as Neo heard these words his grin disappeared he appeared Infront of Kokushibou decapitating him instantly as Kokushibou was shocked as he then woke up as it was Neo's blood lust alone that made him feel like that as Muzan was reminded of the time with Yorrichi as he just growled in anger and fear as Neo charged at Kokushibou only to be pinned down by a sixteenth form as Neo Regenerated back he dashed towards him slicing at his legs only for Kokushibou to jump up and avoid the entire hit as he then fell down and would bring down another 16th form alongside him as Neo looked at him as he took in a breath and sliced upwards as Kokushibou blocked the attack with his sword as there swords clashed as Neo had a big smirk
on his face as Kokushibou was smiling as well, as he hadn't faced an opponent who could rival him in power. Usually it would be him dominating them or just Yorrichi and Muzan who would dominate him in battle as their blades clashed. Neo tried to overpower him but failed as he then just backed off and looked at his surroundings as there was a wall as he charged into it landing on his feet on the wall as he took a breath as steam came out of his mouth as Kokushibou prepared his own breath style as well as Kokushibou launched a moon dragon ringtail towards Neo as Neo would jump of the wall straight towards Kokushibou as a flame dragon appeared as it let out a roar as Kokushibou was left shocked as the attack he launched was disintegrated into ash by Neo's blood demon art as small dragons flew Straight into the moon blades exploding on impact as Kokushibou launched a fourteenth form as Neo kept charging he lost one arm by one of the moon blades as he then launch the giant dragon at Kokushibou with one arm as Kokushibou just sliced it in half while Neo also gets sliced into bits by the attack as he smiled as Kokushibou was declared the winner Kokushibou just stared down at Neo, who was unable to regenerate quickly enough, as Kokushibou thought to himself,
"This was a battle I could've lost if I were inexperienced and didn't have the ability to use my techniques over and over again. This guy really is something; he has the potential to surpass me."
as Neo regenerated back and got back up and smiled
"You truly are quite the foe, Lord Kokushibou."
Neo spoke as Kokushibou just chuckled and turned away and disappeared as Muzan stared at Neo with a big grin as he thought to himself.
"This Neo guy is truly quite the catch, being this strong to almost match equally to Kokushibou at such a young age. Nakime, play a song; I'm in a good mood today!"
he said as he closed his eyes and hummed a rhythm as Neo was in a cave full of pillars and flames surrounding the area as he was sitting on a throne of Nichirin blades with a crown made out of human teeth as he was relaxing his face on his arm as he chuckled.
"I could've beaten him, but I didn't want his dignity to be lost in front of Lord Muzan. I would've erased him."
he said as he sighed and got up and practiced his sword skills, creating new forms for his dragon breathing as the scene shifted to Jason kneeling down in front of Kagaya Ubayashiki as Kagaya spoke to him.
"Jason, your brother betrayed us, betrayed the Demon Slayer Corps. Anything you want to say about it?"
Ubayashiki spoke to him as Jason just sighed and spoke.
"Forgive me, master, for his betrayal, but you don't need to worry about anything; I shall take care of that imbecile and kill him if I find him."
he said as he closed his eyes and opened them as his eyes started to glow light blue as Kagaya just smiled and patted his head.
"You're free to go now, Jason. Sorry for wasting your time."
Kagaya said as he left with the assistance of his daughters as Jason would get up and take a deep breath.
"Well, I guess I'll be training till midnight then."
he said as he walked away as the scene shifted to Emilia hearing the news of Neo's betrayal as she began to concoct different types of poisons mixed with other poisons and wisteria as she poured them into her scythe's chamber and made wisteria bombs as she growled in anger and smashed the table where she was walking, breaking the vials as glass shards pierced into her hands as the venomous fumes got into her lungs and body as she began coughing out blood as Shinobu entered the room in a rush as she heard her coughs as she looked at what was
going on as Emilia looked back at her as veins were popping out of her head as the poison escaped from her mouth with the coughs as she reached out to her as Shinobu rushed to get 3 syringes and extract the poison and stem the blood flow by tearing parts of her haori as Emilia was still coughing in agony as everything stopped as Shinobu injected her with antivenom as it managed to cure her of her poison in her body but not her lungs, as they were damaged beyond repair, as Shinobu looked around as she found a weird mask that looked futuristic as she was confused about what it does as she then snapped back to reality and placed it
on Emilia as she took a deep breath as the mask latched onto her mouth and nose as it now helped her breathe as she would gasp for air as she looked at Shinobu, who was relieved as the mask let her breathe, as Shinobu then took her to the resting area and lay her down there as she took out the glass shards from Emilia's hands and injected her with a tetanus shot and more to have her live as she groaned in pain as she tried and got up but passed out as soon as she did
Shinobu sat beside her, holding her hand like her older sister, as the scene shifted to Jason in a forest covered in blood with his blade covered in blood as well. His eyes would glow a light blue as a demon would be running away from Jason as he reached the tip of the cliff as Jason pursued slowly, his face never changing, as the demon would be shivering while shouting.
"STAY AWAY. GET AWAY. PLEASE, I'LL DO ANYTHING; JUST STAY AWAY FROM ME!"
the demon said as it would fall into deaf ears as Jason would disappear and reappear Infront of the demon with the blade on his neck as the demon's eyes be shown as he was the current lower rank 1 as Jason would take a breath and would go for a slice but would miss as the demon slipped down the cliff as Jason chuckled and walked away as he went to go hunt more demon's as he was then face to face with the upper rank 5 and 4 Gyokko and Hantengu as Jason just stared at them with a cold stare as they both felt the stare as they turned around to see who it was as the next thing they felt was there head flying in the air as blood splashed everywhere as Gyokko instantly dies as Hantengus clones appeared as they we're all instantly dealt with as Jason then slice of Zohakuten's neck as well as he saw the little Hantengu running for his life but with no effort as Jason's eyes we're extremely sharp as he sliced of Hantengu's neck in one sweep as he released steam from his mouth as he looked around as he was now surrounded by demon's who thought he was too tired now but to there disappointment they we're killed instantly before they even Realized anything as Jason sliced down to clean his katana as he walked away as the sun came up as he cleared the area he was in from demon's by the time the sun fully came up as he arrived at the headquarters covered in blood as Tengen would approach him
"You don't look so flashy. What happened? Did you fight an upper rank who kicked your ass?"
Jason giggled and shook his head no.
"I did meet 2 upper ranks, but they were nothing but show-offs. I killed them off in one sweep, but one of them regrew its head and grew out 4 other demons, but still no match for me, and this blood is from all the demons I killed in one night."
he said as he walked away from Tengen, as Tengen was left in shock as he looked back in shock as he just chuckled and went back home as Jason reported back to Ubayashiki as he smiled and patted his head as Jason smiled as well and walked away and took a shower, as he would then go rest after his shower till it was night. As night came, Emilia would be out trying to find demons as she found a lake as she approached it, but it backed away instantly after taking one step as a tentacle would slice off the trees in front of her as she chuckled and looked around at what was happening as there was a red and orange-colored demon as it would lick its lips and say,
"My prey has finally arri—"
before he could complete the sentence he felt something enter his mouth and go down his throat as it would explode as it was a wisteria bomb that just exploded in the demon's stomach but he Regenerated quickly as he groaned as the kanji in his eyes showed upper rank 4 as Emilia was confused as she thought the upper rank 4 was just killed as she just shrugged and charge towards it as the demon sent a black ball flying towards her as she avoided the attack by side stepping as the attack would just erase all the trees it hit as the demon threw another giant black ball at her as she managed to dodge it and scratch it as it opened and began leaking out a black substance that was like acid as Emilia threw one of her chains connected scythes towards the demon as the demon covered himself in a black ball as it hit the black ball with a loud clang as if metal met metal it released wisteria gas as she took a deep breath with her mask as she used
"Breath of poison, fourth form: Scorpion tail strike!"
she said as she threw her left scythe as it made contact with the black ball and released wisteria gas as she threw the right scythe at it as wisteria gas was released as she did this, getting faster and faster with each hit as the whole area was covered in wisteria gas as the demon spun around in the ball as the ball spun as well as it blew away the gas as the demon came out of its ball as Emilia was already in front of it as the demon would be shocked as it trapped her in a black ball as it would laugh and shrink the black ball, thinking of crushing her, as she would just sigh in annoyance as she sliced open the black ball as she stabbed the
demon's neck once with her scythe as she tried to slice through it but failed as the demon let out a roar of anger as Emilia pressed a button releasing poison into the demon's neck as she was then pushed back by a black ball hitting her in the ribs, breaking them, as she coughed out blood through the mask as she dragged her feet on the ground to stop her from flying further as she breathes heavily she couldn't move as the demon laughedbreathed heavily. She and launched himself at her as Emilia ducked down as the demon crashed into a tree as she then stabbed it once more with both scythes as she injected a large dose of wisteria poison.
straight into the demon's head as it became weakened enough to the point it was melting as it let out a roar and whipped her with its tail as she went flying into a tree on her back as the demon let out a roar of anger, charging at her but melting away in front of her as Emilia giggled and passed out from the injuries she faced as a bunch of Kakushi were sent to her location as she was carried away in a stretcher with the Hashira Gyomei by their side as Gyomei was there to kill off any demons coming their way as she was being carried away and reached the butterfly mansion to heal as she woke up and took a deep breath as she
Then she laid back down and groaned in pain as her ribs were still healing as Gyomei would sit next to her and pray as she would stare at him for a moment before she started to pray as well as the scene shifted to Jason in a train alongside Tanjiro, Zenitsu, and Inosuke as they were going to another place to go hunt demons as the train stopped abruptly as there was a silence before it started moving again as Tanjiro and Jason had a delightful conversation about having demon siblings, but one is partners with humanity and one is actively trying to kill humanity and find the blue spider lily.Jason then gave Zenitsu some advice on how to overcome his fears and get Nezuko to like him back as he tried to teach Inosuke basic math but in his own way.
"If there are 3 demons and you kill 2, how many are left?"
Jason asked Inosuke as Inosuke thought and replied with
"GONPACHIRO!"
only to be karate chopped gently on the head
"Wrong, it's 1 here. I'll give you some homework you can do to learn all the names of the numbers, you damn idi—I mean, my dear junior."
he said with a smile as he patted his head as they all go to sleep as the journey was 3 hours long Jason could run faster than the train but he'd rather relax a bit as he started to fall asleep as well before he felt something as he woke up immediately and escortd everyone out of the middle cart every single passenger and the kamaboko squad as the middle cart was sent flying out of the tracks as it broke as the train was stopping as Tanjiro woke up immediately as he smelt the scent of danger as he looked around for anything as the cart would explode as Tanjiro got ready as Jason got Infront of Tanjiro ready to kill the demon Infront of him as he took a breath as he could see 2 orange draconic eyes in the smoke as he was in shock as he took a step back as Tanjiro was also shocked as the 2 draconic eyes then reveal the kanji upper moon 2 as the demon laughed
"LONG TIME NO SEE, BROTHER! I SEE YOU'VE BEEN FAVORITED BY THE SUN BREATHER."
The demon let out a cackle as Jason unsheathed his blade as he then looked back at Tanjiro and said,
"Run now, young Kamado. Live to fight Muzan and kill the upper rank 3. Now go and run away; I'll hold him off."
he said as he chuckled and held his blade tightly as the demon laughed as Tanjiro declined running away as Jason yelled
"GET OUT OF THE WAY, BRAT. THIS IS SOMETHING YOU CAN'T HANDLE. GO TRAIN AND BEAT GYOMEI, THEN TRY AND FIGHT UPPER RANKS ALONE."
he said as Zenitsu grabbed Tanjiro and Inosuke and ran away with them as Tanjiro tried to resist but was overpowered by both of them dragging him away as Jason was left behind. Jason smiled.
"At least they're safe now."
he said as a huge explosion occurred in the area where he was standing as Tanjiro looked in shock and yelled out Jason's name.
