From the ashes of Morioka's body energy began to gather and his hagio began to transform into yoki, signifying that he's transforming into an akuma. The yoki began to take shape from the core where the akuma's heart is located.
The rest were still in shock as of what just happened to their beloved friend (except for Amanogawa).
With tears in Seras eyes, she turned her attention to the tentacle akuma, "Hey, bitch!"
The akuma turned to face Seras.
"I'm going to make you pay for what you've done to Morioka-sama," Sera with lightning flickering on her feet lunged towards them. "With your fucking life!!"
"Tch," They flicked their wrist and sent t5entecles at Seras. Her fist and the tentacles collided sending sparks of electricity flying off her fist.
"Ah, she's going without us," The green-haired demon slayer said.
"What do we do?" The doll demon slayer asked meekly.
Riku got up from the ground and charged towards the tentacle akuma.
"Isn't it obvious, we fucking get revenge!" The black-haired demon slayer charged forward and the rest followed his lead.
'What... no... this can't be happening... this isn't real!! It can't!' These thoughts flooded the minds of Seras and Ciara as they stared at him.
Farasha was as still as rock crippled with both fear and shock of her oldest friend is now technically dead. 'He dies trying to save us and one of us could be next! No! I don't want to! Please, someone, save us!' Tears rolled down the side of Farasha's face.
Amanogawa raised his hand and the card slipped out and trained them for Morioka, Ciara grabbed his arm, "Argh! what are you doing!?"
"What am I doing...? What the fuck are you fucking doing?!!" Small sparks erupt on her palm burning Amanogawa arm.
"Ack! We need to kill the akuma before it forms, right?" He said wincing in pain.
Immediately after saying this he regrets it as more sparks erupted from her hand and he could feel the malice and killing intent coming from the other demon slayers.
"Wait, all I'm saying is that we need to take care 'the akuma' before it attacks us as well." He said.
'Take care of the akuma...!?' Ciara raised a fist and punched Amanogawa in the face, he fell to the ground.
"You self righteous insignificant degenerate! You want to erase Morioka's existence!? His soul will never reincarnate in that 'impure' state!!" She gestured to Morioka's form. "And you think I'll let a jizz stain like you do that to him!! Over my dead body!"
"I-I didn't kno-" He was cut off by Farasha blasting him in the chest, he got knocked back coughing and whizzing.
"Just get the fuck out of here you waste of genes," Farasha's hands dropped, and she rose to her feet. The sight of Amanogawa about to erase Morioka woke her up. "Just count your stars that Ciara got in the way before Seras blasted you from oblivion," They gestured at Seras brimming with electricity as she was finding it hard not to kill him. She deflected the tendrils that the akuma fired at her.
"Now get the fuck away from here," Ciara said calmly as she could muster.
"B-but..." Amanogawa said, trying to reason with them.
"Fucking now!!"
While all this was going on the tentacle akuma watching and a thought came to them, "hmm, that's a waste I could only manage to hit one of those brats with my spell.' She sighed heavily. 'And the one I hit was a weak one, what a waste of my precious yoki. Well, they are all fairly weak compared to the demon slayers but they won't let me hit them, obviously. I've tried a few times.
They glanced at the demon slayer who momentarily distracted after what Amanogawa did, 'And there still that mysterious fist that attacked me earlier, no one has that asha here.' they shut their eyes and could sense no living human able to do that. 'Well at least I can turn the rest and use as an escape, they are all pretty big Hagio, I think I'll take the angry one with purple hair first. She's bound to cause some damage.'
They raised their hand and the asha symbol appeared again and they fired at the Ciara, Farasha screamed right before it was got destroyed by Seras.
"I won't let you turn another civilian," Seras panted.
The demon slayers were busy with the tentacle asha the akuma was using to distract them but only seemed to slow them down but not enough to buy them time to flee.
"Hmm, so you can still dodge my tentacles very good.
"You monster, I'm going to fucking kill you!!!" Seras roared.
"Hmm, I'd like to see you fucking try!!" They sent more tentacles Seras's way.
Seras leapt from the wall bounced off the ceiling rebounded off two walls and shot at her the tentacle demon at the same time the black-haired demon slayer shot them with asha and Riku swung his sword sending sword slashes at them.
The tentacle akuma easily deflected the demon slayers attacks and using one hand block's Seras attack, "Oh, what's this you don't use a spell, to attack. Are you perhaps running low on hagio?"
"Fuck you," Seras grumbled. "Lightning rod!" Seras chanted her entire was covered with runes and she let out a powerful stream of lightning that did huge damage to the tentacle akuma.
They screamed in pain and agony before slamming Seras on the ground and smacking her in the sides with one of the steel tentacles, they got blasted by a powerful gale of wind.
Seras tumbled on the ground and caught by Riku, She looked up at Riku face, "Thanks, Riku." She said.
Riku looked down at her and smiled lightly. 'Wow, this is so unlike Riku to not make a sex joke, but I like this Riku better though, he's a lot more helpful at least...wonder why he's so quiet though?' Riku dropped Sera on the ground. 'Okay, I take it back, he's still an ass. a helpful ass. But an ass all the same.'
Two of the demon slayers ran back to the Seras and Riku, "Captain!" They called out to her.
"Hey, guy-guhfyu!" She coughed out blood.
"Cap!" They slid next to Seras and tried to aid.
"Captain, we got to move now, we are almost out of Yoki!" The jasper-haired demon slayer said. "We Can't last much longer."
"Well, nice observation, point Dexter," She put a hand on her knee. "But I'm not going anywhere until I put that bitch six feet under or finally send Morioka."
The jasper-haired demon slayer was finding this hard to say, but he had to say it, "Boss, this is no time to be thinking about that stuff. We got to be real, we should cut our losses and leave. Morioka-kun was a good kid, but we should focus on keeping the people here alive."
Seras got to her feet and stared at him, 'Did any of that get into her head, why is she responding...' Seras punched him in the face.
"Oy, you want to fucking run so badly, but that bitch isn't going to let us all go scot-free," Seras said. "And that kid is very important to me so I'll die a thousand times for him if I have to." She gestured to Morioka's form. "And don't forget your still fucking alive because of what he did."
The jasper-haired demon slayer gritted his teeth, 'I fucking know that already, but still!'
"I'm going to finish her up then Morioka and then get the fuck home?" Seras walked pasted him. "You can run if you want to!"
"What?" He looked at the black-haired demon slayer and Riku. "Guys, say something."
They both looked at each other, "You want to make Morioka-kun proud by cutting off a few tentacles," The black-haired demon slayer said.
Riku nodded, and they followed Seras. 'Seras was covered in blood, bruises, cut and had severe Riku was no better off. Why the hell am I still licking my wounds!'
The japer-haired demon slayer stretched out his hands, "Volcanic rain!" He chanted.
An asha seal appeared and shot a magma ball that split into hundred of small fireballs.
The aquamarine demon slayer, the green-haired demon slayer and the doll demon slayer were holding off the akuma. They fired tentacles at the demon slayers.
The aquamarine demon slayer put up a wall of a crystal wall to block the attack and only managed to block a few before it smashed to pieces, this bought them enough time to jump out of the way.
"Damn, she's too strong," The aquamarine demon slayer said.
She planted her hands on the ground did a double backflip dodging the tentacles and shot crystals at the tentacles that went after her ripping through them.
The green-haired demon slayer glided backwards on using her cyclone asha, while the doll demon slayer jumped backwards doing somersaults dodging the tentacle.
"Cyclone gust!" The green-haired demon slayer chanted and shot a gust of wind at the tentacles ripping them apart.
The aquamarine demon managed to dodge the attacks that came her way from the green-haired demon slayers attack, "Whoa, ne, watch where you are shooting that thing!" She raised a fist at her.
"Sorry!" she yelled back.
"This is bad, we need to close the gap!" The doll demon slayer dropped to one knee. "We're almost out of hagio!" she huffed.
She looked down at her friend as she was huffing and nearing her limits. "Got it, I have just the thing!" The green-haired demon slayer clasped her hands. "Cyclone mist!"
There was an asha seal under her and a heavy covered the entire area the akuma couldn't see past her hands but they couldn't run away because they can still sense where they were.
The aquamarine demon slayer knowing what she was thinking shot her crystals at the akuma at the same time the doll demon slayer fire an attack at her, the akuma seeing the energy signatures blocked their attacks. from the side, the green-haired demon slayer managed to get a few shots on her.
As they flew backwards, the marine and doll demon slayer leapt in the air and fired at them. They managed to dodge this attack and they shot tentacles at the demon slayer, knocking them against the wall.
"Fools! Did you really think that you could get me with an attack like that!" Then she noticed the fireballs coming at her. "Ah, crab cakes!" They got a direct hit on her but also hit the other demon slayers in the process.
Riku, Seras and the black-haired demon slayer managed to jump out of the way of the attack into before the got in the mix of it.
"Whoa! what the actual fuck, Dude!!" Seras yelled.
"Ahh, sorry I got cut up in the heat of the moment." He scratched his head nervously.
"Next when you get 'caught up in the heat of the mother fucking moment' leave me the fuck out of it," Seras said as Riku tapped the fire off Seras's body.
the black-haired demon slayer put a hand over his eyes, "Hey, cap', I think that he did some damage to the akuma."
"Oh, that's nice... well at least." Seras sat cross-legged while Riku put her out of the fire. "Wait, what the fuck! It took some mother fucking damage!!!"
"Yeah, so what's the..." His question was answered for him when multiple tentacles filled the entire area.
Farasha and Ciara were still by Morioka's side, Ciara still wiping the tears from her eyes as she looked at Morioka forming into an akuma. Amanogawa was already gone before Ciara or Farasha killed him.
"It's okay to cry, Ciara." Farasha finally said.
Ciara fidgeted, "What? Crying? I'm not crying, it's just akuma dust. Yeah, that's it. If anyone..." She turned to see tears rolling down Farasha's cheeks.
"Yeah, they don't stop coming down, it's kinda hard to see now." She sniffled. "You know it's funny, you'd think that having so little hagio, that Morioka-chan will be the first to crack, but he's always the first to act."
"Yeah, he w-was!" She chocked at the words, it was still hard to accept his death.
"Ciara-chan, you know what we have to do once that thing takes form, don't you?" Farasha asked.
Ciara avoided eye contact with Farasha, 'I already know that damnit! It's not fair, we are all almost out of Hagio and these damn akuma keep coming!' She punched through another akuma. 'Damn why are they all so weak, aren't there any humans alive,' She looked around. 'Hang on there should be humans under debris even if the humans that Farasha and Morioka saved got away there should be some here, why aren't they going after them, it's not possible...could it have turned them all into akuma. But, why that doesn't make any sense.'
"Ne, Ciara, what do you think goes on in there when they turn to akuma. Do you think they have a little bit themselves in there?" Farasha asked.
"Don't be dumb, Farasha-chan. They die and then reborn as akuma. Now get off your ass and come help me!"
"Aye!" Farasha got up from the floor.
In an empty space filled with nothing further than the eye can see, Morioka opened his eyes, he looked and then right.
"Huh? so this is my mindscape," He heaved a sigh of relief. "Oh, thank goodness I was right, otherwise that would have been the end for me!" He slumped over.
A powerful voice crept in with the darkness in the deepest corners of his mind saying: "Join us!"
'Hmm, nope!' He snapped his finger and almost immediately the voice and darkness disappeared and he was left alone again. 'Hmm, something's not right here... oh, right!' He clapped his hands and naked busty women and men flew all around him. 'Ahh... now that's better!!' He put a hand to his chin as his nose bled.
Seras and Riku were bouncing off the walls and ceiling trying to get the akuma but they were too strong for them. The akuma sustained some damage from the earlier attack but nothing they couldn't work through.
"Damn, it's getting even hard now!" Seras grumbled. "Oy, I don't suppose you have any more attacks you can use to pin it down," Seras yelled.
"No, that was the last of my hagio," The magma demon slayer said.
"Seriously, you used up all of your asha in one attack?" The wind demon slayer said.
"You should have brought some ergo," The doll demon slayer said.
"Oh, I'm sorry, next time I'll bring out all my akuma fighting equipment with me in case a crazy akuma attacks!" He yelled.
"Wait, why didn't we?" The earth demon slayer asked.
"I've so relaxed with these weak akuma's these past few months that I forgot what a powered out battle is like and now we are so ill-prepared," The crystal demon slayer said. 'Hang it's been an hour since she started attacking, why is there no backup, shouldn't civilians have made it to the surface by now?'
Riku zipped through the slashing and hacking through the tentacles that blocked their path while Seras conserving her hagio dodged as many tentacles as she could.
'Damn this is getting endless, how do I land a decisive blow on it?' Seras thought.
"Hmm, Your becoming slower, maybe I should turn those other kids as well!" The akuma grinned.
"I won't let you!" Seras launched off a steel tentacle.
The akuma lunched tentacles at Seras, she dodges the attacks and they trade flew blows, Seras trying her hardest not to use her Hagio when she got caught in the chest by a tentacle. Riku lunges forwards and cuts the tentacles that come his way and slashes his chi swords at them.
The tentacle akuma deflects this easily but then he picks up speed and his chi swords become more powerful as he hacks at her. He took a few steps back and swings his swords wildly chi slashes sent at them cutting through their defence.
They jump out of the way and get hit in the face by a fist made out of the darkness.
'What? again with farce!?' She thinks as the punch sends her flying.
In mid-air Seras charges with a knee, they block it hit Seras in the face and Seras kicks them on the sides as they both get sent flying.
The akuma get up first and lunges at Seras Riku intercepts, "Die!" They shot tentacle at Riku but he manoeuvres around it and slashes at them.
They deflect it then Seras punch her in the face with an electric filled punch, the akuma returned the favour and began trading blows like that until the akuma noticed that Seras was slowing down and kicked her in the chest at that moment Seras poured all of her remaining hagio into the pulse she place in the palm of her hands and slammed it on their shoulder.
The attack stunned her long enough for Riku to lunge forward and stab her in the chest.
"Ahh!!" they cry out and kicked him in the chest. He flew back past Sears and slammed against the wall and slumped on the ground coughing up blood.
"Riku!" Seras yelled and ran to his air.
At that same moment, the akuma got hit in the face by the fist of darkness. As she flew in the air and saw the rest and fired her demon curse at them.
The demon slayer managed to get out of the way, but Farasha and Ciara were petrified and couldn't move.
"Move you dumb fucks!" The wind demon slayer said.
Back in Morioka's mindscape, he looked annoyed at this fruitless attempts by this unknown entity.
'You... uh, ready to make a bargain...?' He said.
'And why would I bargain with the likes of you?' It asked.
'Because you've been trying for some time now no headway, plus you're invading my mind. So do you want to make a deal or not.'
'....' There was silence.
'Hello? you still there?' He asked, unsure at this point.
'You have such a strong mental fortitude... you have gained my respect, so what do you wish for? Freedom? You know they would never accept you.'
He grinned, 'Hmm, I'm actually pinning after something else, actually.'
As the curse was about to hit and everyone else was either too weak to move or out of hagio to reach them in time Morioka's form completed and he was able to.
He got in the way of the curse and took it all, which did not affect him anymore, "Yare, yare, you guy's are a handful." He said the asha peeling off of his form.
