A Grim Revelation

"Ice spears!!"

"Boulders!!"

"Storm of swords!!"

*BOOM!!*

*BOOM!!*

*BOOM!!*

"Haah... Haah..."

*CRACKLE!!*

*ZOOM!!*

Blitzing through the purple underworld magic and the bombardment of new attacks through the use of [Thunderclap and Flash Eight Fold], Grim found himself breathing heavily as his [Hyper Focus] was pushed to the limit.

"ARE YOU FUCKING KIDDING ME!!" He yelled at the devil who was seemingly enjoying the show.

"WHY ARE YOU BEING SO FUCKING EXTRA!! WASN'T THE UNDERWORLD MAGIC ENOUGH FOR YOU?! YOU SICK BASTARD!!"

'And what the fuck happened to Yami and the elf bitch inside captain Charlotte's body?'

After unleashing this magic, the entire area had quickly been overrun by the purple underworld tentacle thingys and he had lost sight of the others in all the chaos.

"Fufufufu." Zagred laughed watching him struggle in vain. Despite the hellish pain in his body that made it feel like he was being torn apart, seeing Grim desperately run around in an attempt to survive caused the smile on his face to deepen to unfathomable levels.

From all the pain and humilition he was forced to suffer by his hands, he'd make sure to pay him back a 100 fold!

To that end, he would continue to bombard him with these "extra" attacks just to piss him off.

Was that petty of him?

Yeah, but fuck you he's a devil.

[Breath of Wind]

Dashing through the sea of underworld magic, the yellow hue on Grim's body slowly transformed into that of a pale green as slashes of violent winds began to surround his body.

[Dust Whirlwind Cutter]

*BOOM!!*

With his body surrounded by a raging cyclone that tore through all the underworld magic around him, he charged forward at blinding speeds and dove straight into the heart of Zagred's spell.

Using his elemental affinity to create ultra violent winds that surrounded his body, he drilled through the solidified magic and kept diving until he was deep enough that all sound had vanished.

[Breath of Blue Flames]

---

While Grim was busy diving in the underworld magic, everything on the surface had quietend down.

"Hmm" Zagred hummed thinking that Grim had chosen to give up on living after seeing him jump into the heart of a magic thats only function was to steal someone's magic and lifeforce from them.

'Was the spell to much for him to handle? *sigh* And I was really looking forward to breaking hi-

*BOOM!!*

!!!

Before he was able to finish his thought, in that moment of stillness where the world had fallen silent, a blinding pillar of blue flames errupted from beneath the surface of the devil's underworld magic. Bright blue light lit the room as a deafeaning sound ripped through the otherwise tranquil environment.

Feeling his eyes go wide at the sight of the sudden explosion, Zagred couldn't hide the shock on his face when he saw the pillar of blue flames rise from the ground. From its flames came an intense sense of danger. It was something akin to an instinct. A feeling so strong that he couldn't ignore it. He didn't know if it was because he took a smaller explosion to the face earlier today, but right now, something inside of him was being born. Something that made him uneasy.

And it was at that moment that he understood what it was. Scattered by the explosion and shockwave, chunks of solidified underworld magic rained from the skies. But on these pieces that had been separated from the rest clung embers of blue flames... Flames that burnt away at the chunks until they became ash.

'Impossible... Impossible! He's burning magic... my magic! Underworld magic! Something not of this world shouldn't be destroyed so easily and yet...'

Watching the pieces of the underworld magic become ash before even managing to touch the ground, that uneasy feeling in his chest grew heavier as he began to understand what Grim's magic was all about.

*Flashback to Grim landing attacks on him*

His magic... It didn't target devils, it never did, it does something worse, far worse.

It destroys what we're made of.

What we're born from.

What we live in.

And what we survive off of!

His magic... it destroys negative mana.

---

It all made sense.

The reason his mana was supressed from the moment they fought.

The reason why his spells were only half effective when he focused on him.

The reason he was able to feel such long lasting pain despite healing.

It all made sense. And to further confirm his point. The magic he summoned from the underworld was the solidified form of negative mana... For Grim's fire magic to turn it into ash...

"Oi." A voice suddenly sounded out from the area the flame pillar appeared from.

With the explosion gone and the dust cloud disipating, the sight of Grim's infamous smile reflected off of Zagred's eyes. Covered in wounds he got from the solidified underworld spell touching his skin and draining his lifeforce, he stood tall gripping a sword thats blade was completely covered in blue flames.

"Haah..." He released a breath and swung his blade shaking the flames off before looking up at the devil who was flying above him.

'W-What is this feeling... My body... Its trembling...'

"Devil." Grim voice sounded out again as his feet slowly left the ground and his body entered the air.

'Something's wrong... This guy... His entire vibe's changed!'

Gritting his teeth and refusing to believe that a crossbreed of two inferior races could make him feel this way, he opened his arms and used his [Hell Language] to summon creatures from the underworld into this dimension. These creatures had long snake like bodies and besides the visible sharp teeth in their mouths, they had no other features on their bodies. No eyes. No noses. No ears.

"DEVOUR HIM!!" Zagred screamed.

*ROARR!!*

Hearing his order, the creatures bolted towards the motionless Grim who was chilling in the air.

"DIE!!"

*Grins*

[Thunderclap and Flash]

*Crackle*

*ZOOM!!*

Turning into a bolt of lightning, he flashed forward and appeared right in front of the leading monster. But right before he could be turned into the creature's snack, the glow around his body suddenly became a calm blue.

[Breath of Water: 3rd Form - Flowing Dance]

Utilizing the special properties of this form, his manuverbility skyrocketed allowing him to easily perform a twisting dodge that had the creature shoot right past him while he plunged his blade into its side and carried on flying towards Zagred.

[Breath of Flames: 1st Form - Unknowing Fire]

With his blade still in the creature's body and this spell active, Grim's blade began burning with a savage light as violent flames burst out of the other side of the creature's body. Looking like he was covered in flames and shooting up at blinding speeds, the flames burned the creature from the inside out as he made a long horizontal slash that completely split it in half before charging the other descending creatures.

*SWOOSH!!*

*SWOOSH!!*

Feeling the wind push back against his face, his expression became harder and harder to read. Besides the smile he had, it almost looked as if he was expressionless.

'What focus!'

*SWOOSH!!*

*SWOOSH!!*

Weaving through the falling underworld monsters, the hue on his body rapidly changed colours as he shot past them and let his spells do the work.

[Eight Layered Slash]

[Crazy Cutting]

[Flame Tiger]

[Claws Purifying Winds]

Destroying them as they came, the distance between him and the devil drastically shortened to the point that Zagred was starting to feel some pressure.

'I can't let that blade touch me.'

*Clenches fists*

[Hell Language]

Using his [Word Soul Magic], a weird looking trident manifested in his hands.

'Yes. With this trident that's capable of dismantling everything it touches, I should be able to kill him! Even his swords will be destroyed once they come in contact with it and it'll be my victory!'

[Thunderclap and Flash]

With flashes of lightning dancing across his body, Grim turned into a bolt of lightning and shot towards the devil.

Feeling confident now that he had this trident, Zagred grit his teeth and shot downwards.

'I have a physical body, I finally have my own grimoire, nothing in can kill me. NOTHING CAN KILL ME!!'

*BANG!!*

Clashing into each other head first, the smile on Zagred's face grew wider as he realized that Grim had defended with his sword. Unfortunately that smile didn't last.

*SHATTER!!*

'I-Impossible...'

While what he was using was an object that destroyed what ever it came into contact with, Grim's Beast Swords had the special properties that allowed it to cut anything made of magic. The moment both weapons clashed with the other, Zagred's trident began destroying the blades while Grim's swords began slicing through the trident ultimately leading to the destruction of both weapons the moment they touched.

'He destroyed a weapon capable of distorting space and destroying everything.'

*Grins*

'BUT I CAN JUST CALL FORTH ANOTHER!!'

Using [Hell language] once more, Zagred called forth another trident and struck down at the now defenseless Grim.

"DIEE!!"

*SHATTER!!*

'What!!'

Although he had been right in his assumption that Grim was defenseless, he underestimated the speed in which he was able to materialize new swords.

'Again!'

*SHATTER!!*

'Again!!'

*SHATTER!!*

'AGAIN!!'

*SHATTER!!*

'AGAAAAAIN!!!'

*SHATTER!!*

Clashing with Zagred's trident over and over again, Grim subconsciously racalled his fight with Asta in the Witches Forest.

Remembering this fight caused the smile on his face to widen to a scary degree that it made the literal devil in front of him uncomfortable.

[Crazy Cutting]

Since Zagred was capable of materializing weapons as fast he could speak, Grim tried attacking faster than he could talk.

[Flowing Dance]

And since he still had to watch out for that trident, he used a spell that gave him the greatest manuverbility.

With both spells blending into each other thanks to his extreme level of focus brought along by his ability [Hyper Focus], he was at a completely different level compared to the time he fought Asta.

---

"No, no, no, no, no, no, no, NO!!"

"This shouldn't be possible!"

*Slash!!*

"Arghhhhh!!! HEAL!!!"

Feeling one of Grim's Beast swords slice him thanks to [Crazy Cutting], Zagred wasn't able to hold back his screams as he was forced to heal for the nth time.

'My regeneration... Its getting slower! I... I have to run.'

Realizing that the tables were beginning to turn, Zagred did the smart thing and turned tail.

*BOOM!!*

Executing the fastest speed he was able to produce, he ran. He ran as fast as he could.

"GET BACK HERE!" Grim roared using [Thunderclap and Flash] to chase after him.

"GET AWAY! GET AWAY!! GET AWAY!!" Rapidly spouting off the same phrase over and over again, Zagred prayed that it would slow him down long enough for him to escape.

With nowhere else to go other than the lower levels he had escaped from earlier, he flew down towards the hole in the ground that had been covered by the purple underworld eating magic he had summoned earlier.

"MOVE!!" He screamed forcing the underworld magic to give way.

But just as he was about to re-enter the lower levels, Asta, Yuno and Patri who was no longer in his dark elf form burst out from the hole.

"We got you ya sleezy bastard!!" Asta yelled as the trio charged towards him.

'NOOO!!! WHY'D YOU APPEAR NOW!!'

Unfortunately, the surprises weren't over just yet.

*BANG!!*

'What now!!'

Exploding out from a large clump of the underworld eating magic, Licht finally appeared again.

'How is he still here! And why is it that only his clothes have taken damage?!'

*BOOM!!*

'NO! WHY DO MORE AND MORE PEOPLE KEEP APPEARING!!'

"DEVIL!!" An unfamiliar voice sounded through the area as a man made of stone and a black haired girl with two small horns at the side of her head broke through chunks of underworld eating magic from above.

Surrounded by light magic, they naturally caught everyone's attention, including Grim's.

'Tch, and I was finally getting into it.'

So... Grim's magic actually targets negative mana. Bet a lot of you guys didn't figure that out lol.

And forget devils, since even the underworld is made from negative mana, the underworld and all it inhabitants are his prey. I mean did you see how he destroyed the underworld creatures like they were nothing?

Anyway, we're approaching the arc's endgame.
