The group were charging at the Demon King ready to fight him

DK: Really, you guys amaze me... but you have not learned your lesson

Ban proceeds to try to take the Demon Kings power but collapses from his strength being stolen

DK: Trying to steal my power that much. Will only make me stronger

Wild charges at the Demon King as it only becomes ineffective

DK: Trying to pierce me that much. Won't even scratch me

Meliodas then goes to attack only for a barrage of black lightning strikes him

(Y/N): CAP

Meliodas: REVENGE COUNTER

Meliodas sends a massive amount of magic at the Demon King only to do nothing as the Demon King goes to punch Meliodas as (Y/N) gets in the way, but the two still get hit far away.

DK: your technique is just a fake, less powerful copy of chandler's. Without using your original magic power, you don't stand a chance against me. But this is impossible. Because you are afraid.

The four got blown away from the Demon Kings attack as they sit around only for Meliodas to wake up

Meliodas: where is the Demon King?

Ban: very far from here

Wild: to be exact, we were the once that were blown away very far from him.

(Y/N): just like every other time

Meliodas notices the huge amount of blood covering (Y/N) left side

Meliodas: Fire... this wound?

(Y/N): oh this, it's just a flesh wound

Ban: He got it from protecting you Cap'n

Ban hits (Y/N) side making him wince in pain, as Meliodas looks sad that he got another friend hurt.

Ban: let me take a look there

(Y/N) feels a strange sensation as his body starts to close all of his wounds

(Y/N): wow, that was new

Wild: the wound has healed?

Ban: Oh, really?

(Y/N): seems that way

Meliodas: Ban, what did you do?

Ban: in the last 60 years I tried to steal the Demon Kings power and physical strength using all means I could, but instead my power was absorbed. Thanks to that I could learn to "steal" ... no, to "give" sensation. And I wanted to give it a try.

Wild: But sir Ban, will you really be okay?

Ban: sure! I'm immortal after all. (Ban looks at his hand) with this power, I could-

Wild: even so, "the ruler" is really scary. How are we supposed to pierce him?

(Y/N): we can't even land an effective attack at this rate

Ban: So, Captain, is it true what the Demon king said?

Meliodas:!

Ban: when he told us that you cannot beat him without your original magic power? It's it true what he said about the full counter being a technique that you learned from that demon geezer? So, your original power is completely different, Captain?

Meliodas: ....

Ban: ....

(Y/N): ....

Meliodas: Well, well, well? Are you really that worried about me?

Ban starts giving Meliodas a death glare as Meliodas avoids eye contact.

Wild: (spinning in circles) anyway, if we can't beat "the Ruler". I won't be able to see Mild again. KUOOOH! Is there nothing we can do?

Ban: even if I use "snatch". I'll only end up fortifying him instead of weakening him. If we use the full counter, that is capable to rebound all magic attacks, everything will be absorbed.

(Y/N): even mine and Wilds attacks have been in vain

Meliodas: Obviously that doesn't apply to things that he cannot rule...

(Y/N): something he cannot rule, hmm

Meliodas: you got something?

(Y/N): well, the power I mentioned is close to complete now, the only problem is that there is not really a way for me to use it properly. I mean, I could use a weapon made here, but it will just disintegrate.

Meliodas: hold on, that's it.

Ban: what's it?

Meliodas: I have an idea, listen up.

The group after hearing Meliodas plan head to the Demon King, as Ban gets ready to steal his power.

DK: I am so impresses that I cannot even sigh. Did you really try to steal my powers again?

Ban: Ha. If I cannot steal your power, I will just give it to you right from the start.

Just then the Demon King dropped to his knees as is strength vanished

Wild: ooh

Meliodas: Demon King. The true identity of your magic power, "the ruler", is "inversion" you convert all attacks and weakness you receive into healing and fortification.

DK: listen well, emotions of Meliod- rather of my son. I will never allow you to return to the real world.

Meliodas: THEN WE'LL FORCE OUR WAY THROUGH

The group runs pas the demon king, only for him to regain some of his strength allowing him to raise his sword.

DK: I won't permit it

Ban: oh, o think you will

Ban starts to give some of his strength to the demon king making him lose his own strength in the process

(Y/N): Ban what are you doing

Ban: don't worry about me. Just hurry up and find the gate. I'll hold him off

(Y/N) reluctantly follows Meliodas and Wild as the find a hole with no bottom

Wild: Sir Meliodas, Sir Fire, it really was here after all, the door to the other world

Just then Ban sound to be in pain. They turn around to see the Demon King holding onto him

Ban: he. Got his strength back?

DK: I simply deactivated a few spells, that's all. In other words, I let the damage you were trying to inflict upon me heal me instead...

Ban: DAMNIT... DON'T UNDERESTIMATE ME

DK: OOOOHH? A mere human is able to struggle against me

Just then an explosion occurred behind him taking the Demon Kings attention away from Ban, only for him to be punched in the face with a giant fist. The Demon King drops Ban as another giant hand catches

Ban: what the

Ban sees the hand is connected to that of a giant ape, the ape then places Ban on the ground.

???: you better get out of here you need to go and revive Elaine remember

Ban: Fire?

(Y/N): yup, now get out of he-

(Y/N) proceeds to be hit by the Demon Kings blade, digging deep into his side

DK: I won't let you escape

(Y/N): you don't get a choice

(Y/N) sledgehammers the Demon King head sending him to the ground as the Demon King with his sword strikes (Y/N)'s legs sending him to the ground. As the Demon King rises above him

Meliodas/Ban: Fire!

(Y/N): don't worry about me. RUN

They hesitate of a few seconds giving the demon King a second to strike in their direction cutting the land open

DK: I have decided that you won't escape and that is finale

(Y/N) uses this as an opportunity get behind to put the headlock on the Demon King preventing him from doing another attack

(Y/N): go, I will be right behind you

As Ban, Meliodas and Wild were about the escape a bolt of lightning strikes the Demon King and (Y/N) causing (Y/N) to let go. (Y/N) collapsed to the floor as the Demon King turned quickly to strike (Y/N) down but missed as (Y/N) rolled to the side before he punched the Demon King, only for the attack to be ineffective.

(Y/N): oh no.

DK: you thought that that would work

(Y/N): sort of

A sudden barrage of slashes cut open (Y/N) body causing him to collapse

DK: this form of yours is strong, but your body becomes weaker. It is clear that this is used for intimidation, but that won't work on me.

(Y/N) body slowly reverts back into what he once was

DK: but this ends for you

The demon King was about to slash at (Y/N), but was stopped by a tremendous force, as Wild could be seen covered in lightning

Wild: Wild Full Throttle, this is my final resort... my ultimate technique. I explode the life force I have within me and strike down my foes

(Y/N) slowly rises covered in his own blood

(Y/N): Wild what are you doing

Wild: Sir Ban, Sir Meliodas! Get in front of the door

Ban: what's he planning to do

Meliodas: don't know

Wild proceeds to kick (Y/N) sending him flying towards Ban and Meliodas

(Y/N): coming in hot

(Y/N) hits Ban and Meliodas as the three fall into the hole

DK: you're not getting away

As the Demon King tries to grab onto them, Wild gets in the way knocking the Demon King off course doing damage to him in the process.

Wild then feels as if he can't move any more

Wild: it appears this is as far as I go.

Blood explodes from Wilds body as he drops

(Y/N)/Ban/Meliodas: WILD!

The three slowly fall

Ban: damnit... my body won't move the way I want to.... CAP'N! GRAB MINE OR (Y/N) HAND OTHERWISE WE WILL BE SEPERATED!

Meliodas: we're being separated? So that's it. We're both being pulled towards different objectives. You two came to purgatory through Hawk... meanwhile I... am returning to my true body that's becoming a cocoon for incubating the commandments

Ban: ...

(Y/N): ... you know, I wish Wild got to meet Wild at least for a moment.

Meliodas: yeah

Ban: Perhaps I should let master hear that song once I get back, how did it go again? *Cough* *Cough* Goood niiiight~ my sweeet little brotheeer~

Meliodas: I wonder if he'll remember at all? This is Hawk we are talking about that here

(Y/N): that may be true, but I bet that song will trigger him to remember, even a long-lost memory from a time long forgotten by most

Meliodas: yeah, I guess so

Ban: even if he remembers or not, I'm sure that Wild would be happy

Meliodas: yeah

(Y/N): true

Just in that moment a large hand enters from the exit point grabbing hold of Meliodas

Ban: CAPTAIN

DK: HAAAH, HAAAH, HAAAH I've got you. I told you, didn't I? That I won't let you get back to the real world.

Just then a yellow whip wraps around the demon king's arm as it then flicks a red light that flies out the hole as it strikes the demon king in the head causing him to let go of Meliodas as (Y/N) could be seen in his red-haired form.

(Y/N): you two better get going

Meliodas: Fire what the hell are you doing?

(Y/N): getting you two morons out of here

Ban: what the hell, we were supposed to get out together

(Y/N): I won't let Wild's sacrifice be in vain.

Meliodas: Fire

(Y/N): thanks for everything. I'll see you around late

Meliodas/Ban: FIRE!!

The two fell through the gate returning them to the other side

(Y/N) simply smiles before returning to face the demon king who if furious by what just happened

DK: YOU DARE LET MY SON ESCAPE, YOU WILL PAY FOR THIS

(Y/N): I know I will.... but I don't regret my decision, not in the slightest.
