Endless Shadows

'Damn it!' Nacht cursed as the storm cage raged on in front of him.

With his hair blowing from the wind, he bit down on his lip hard enough that the taste of blood spread through his mouth. With the way things were going right now, it was only a matter of time until Grim's mana levels fell to the point that he could no longer maintain the [Storm Cage] and those devils escaped!

'If those devils were allowed to run loose...'

With no real way to damage the twins, the moment the [Storm Cage] fell it was GG for the rest of them.

'I can't let that happen.'

*BADUMP*

'I must destroy evil...'

*BADUMP* *BADUMP*

'I must stop the devils...'

*BADUMP* *BADUMP* *BADUMP*

'I must save us!

*BADUMP!!* *BADUMP!!* *BADUMP!!* *BADUMP*

*Stares at the [Storm Cage]*

'No matter the sacrifices...'

"Plumede... Wagner... Come to me."

*FWAAARP*

Crawling out from deep in his shadow, the cat and chicken mask wearing devils stood on his shoulders. Now in their small familiar forms, the two were ready to serve.

""Master Nacht."" They said in union.

*Exhales*

'Just this once... I'll put my faith in Yami's ideology.'

Now that all the pieces were in place, it was time to end this.

Clenching his fists tightly, he poured his all into the bond that existed between him, Plumede and Wagner.

"HAAARGHHHHHHHH!!!"

Allowing an insidious amount of devil mana to build up inside of him and then letting it run rampant through his body, the pain it caused felt like a million ants were crawling all over his body and tearing away at his flesh.

"HAAAAAAARGGHHHHH!!!"

Screaming out at the top of his lungs, it took all he had to not pass out from the pain as malicious looking black shadows burst out from beneath him and submerged the three in its inky darkness.

If a devil union with one mid-ranking devil isn't enough to face a Supreme Devil, then I'll add two!

If that doesn't work I'll add three!

If that doesn't work then I'll add four!

I'll add and add until I can't add anymore!

I'll keep adding until my body breaks!

Because right here, right now!

I'LL SURPASS MY LIMITS!!

With his teeth clenched down against each other, he forcibily formed a three-way devil union.

[Devil Union: Gallus x Felis]

*CAAAAAWW!!!*

Breaking out of the shadows that submerged him with terrifying might. An unnatural amount of power that surpassed everything he was capable of before displayed itself. With pain filled bloodshot eyes and looking like an unholy fusion between his [Devil Union: Felis] and [Devil Union: Gallus] forms, he let out a loud caw as his bird-like wings unfolded from behind and took him to the sky.

*FWOOSH!!*

Not wasting any time and soaring high into the air, his eyes locked onto the [Storm Cage] below.

Inhaling deeply, his grimoire pulsed with demonic power as its cover fluttered open.

[Shadow Magic: Monument of Atonement]

As he was now, with the combined power of himself and two mid-ranking devils, he could temporarily boost the potency of a single spell to the level of a supreme devil.

Raising his right hand up and lowering his left so that it lay below his waist, two halves of a massive black tomb shimmered into existence. With the Storm Cage in the middle of both halves, Nacht slowly brought his seperated hands together.

'Grim... Since you're so adamant about fighting those devils all by yourself, I'll fulfil your wish and trap you in a world of endless shadows! In a world without light, life and death. Fight to your heart's content for the rest of eternity!'

Not having any positive feelings towards Grim in the slightest. Nacht didn't hesitate to bring both the bottom and top halves of the tomb together and trap the three inhuman beings in a world of darkness.

"This battle..." Having forcibly used a spell beyond his means, sweat trickled down Nacht's face as he tightly clutched at his chest and breathed heavy. "It's my win." He smiled slyly as he watched the tomb fade from this world.

Unfortunately, fate seemed to have different plans.

*BOOOM!!*

Not even three seconds after declaring his victory, the violent mana of Grim and the two devils reappeared.

'T-This is impossible!'

Returning with renewed vigor, a violent discharge of powerful lightning, flames and ice burst out from the endless void as the three returned to the material world.

"My spell..." Nacht muttered falling to his knees as his transformation undid itself and his mana slowly dispersed.

"My endless world of shadows... They broke something that doesn't physically exist."

'What kind of monster am I looking at.'

Powerful was no longer enough to describe them, they had reached a level that he couldn't even fathom. Elves and Devils... This strength... it was a domain that humans couldn't tread into.

Devil Flame Magic...

Devil Ice Magic...

Magic capable of burning and freezing everything without question. Even shadow and light... and even invisible concepts...

"Ha...Ha...HAHAHAHAHAHAHAHAHAHAHA!!" Discharging even more lightning and crushing the surrounding icicles, Grim gripped his sides and started laughing alongside the twins.

"Fuuuun!! This world is so fun!" "Mooore! I want you to entertain us even more!!"

Listening to the laughter of the three, the light of hope in Nacht's eyes was slowly starting to fade as he realised-

This whole time... They were only playing...

'We've lost. No matter how strong Grim is, if he's unable to hurt them nothing will change.'

But just as he was about to fall into despair, a hand suddenly landed on his shoulder.

"Grim..."

Grinning like a fool and not even bothering to even spare him a glance. The only thing in Grim's eyes at the moment were the two devils. Opening his mouth, he spoke with a voice that rippled with excitement. 

"I get why you did what you did shadow guy." He grinned. "Since they're invulnerable to all forms of physical attacks, you thought I would lose right?"

*Grins grows even wider*

"But didn't I say it when we fought earlier - I'd Win"

"You... You still think you can win?!"

"Of course." He smirked.

Removing his hand from his shoulder and walking forward, with every step he took the lightning rippling around his body grew more and more intense. Looking like a true storm god, his presence only seemed to grow.

"You said I can't hurt them physically?"

Continuing to walk forward, the lightning around his body began to fade as his outfit started glowing white and white flames manifested out of nowhere and began to consume his entire figure.

"Well then *smirks* watch me."

[Breath of the Kitsune]

Allowing the flames to completely engulf him, he continued onwards as he stepped out from the flames in a completely different outfit and with white colour fox ears sitting on his head.

'This... Its the form he used to beat Conrad.'

"Oh?" Sensing a change in the world, both Nahamah and Lilith were drawn to the transformation.

"This human... He's truly interesting."
