Chapter 45 - Mirror Force

Leaving a trail of fire in his wake, Grim shot forward with explosive power as he closed the distance between him and the monster.

"D..ie.. You... will die..."

*BANG!!*

Dodging the fist of the giant mud monster, Grim charged forward with a smile on his face.

*BANG!!*

*BANG!!*

*BANG!!*

[Dust Whirlwind Cutter]

Switching breath styles, Grim launched himself high into the air until he was at a height that surpassed the monster.

"DIE!!!"

[Breath of Flames - 9th Form: Rengoku]

*BOOM!!*

Releasing the high powered [Rengoku], Grim watched in satisfaction as a hole appeared in the monsters ċhėst.

"Fuck Yeah!!"

"Hehehe, that's not enough Grim." The girl laughed as the hole in the monster's ċhėst started regenerating.

"D...IE!!" The monster shrieked as it attempted to swat Grim out of the sky.

Using [Dust Whirlwind Cutter] again, Grim avoided getting hit and shot towards the ground.

'It can regenerate... I guess that means this is a battle of attrition... I wonder who'll last longer?]

Realizing that this monster could only regenerate due to the now massive amount of mana it had, Grim wanted to force it to use up all that newly gained mana and kill it once it ran out. The only issue was that this plan depended on him not getting hit and being turned into paste before its mana ran out.

'Guess I'll keep injuring it and force it to use up all its mana healing itself.'

---

"Give up Grim!! Just let me capture you and Asta." The girl yelled watching Grim evade every attack.

"PISS OF OFF YOU NERDY LOOKING CUNT!!"

"Aha, I really like you!!" She grinned.

"English muthafucka! Do you speak it!?"

[A/n: I know they don't actually speak english, but that line was to good to pass up]

Clenching its muddy fists, the monster looked down at the white haired Neige that was still alive despite losing quite a bit of blood.

"B-Baro..." He looked up at the mud monster with tears in his eyes. "I-Its me Neige."

*SWOOSH!!*

Not understanding his little brother's words, the monster swung its fist downwards.

"Oh for fuċks sake!!"

*Slash!!*

*BOOM!!*

"Y-You saved me." Neige stuttered in shock.

"Saved you? I'm just making sure that I'm the one that kills you and not this thing."

"What?"

"Just think about how humiliating it'd be if I failed to killed you but this giant piece of shit did? I can't have that."

"Y-Your still going to kill me?"

"Obviously."

"Oh..." A forlorn look appeared on his face.

"Now then, back to the monster."

*RAAWWRRR*

Grinning at the sight of the mutated Baro, the glow around Grim started to change from orange to a gray color.

"Hmm? Is that another magic type?" The girl wondered after seeing two jagged swords appear in his hands.

Closing his eyes, Grim stood proudly as he took in a deep breath.

While [Breath of Flames] seemed to be the most effective magic type to use against Baro, [Breath of the Beast] was the magic that he was most proficient in and felt comfortable using.

Taking a step forward, he watched as the monster healed its hand and threw another punch down at him.

*Deep Breath*

*BOOM!!*

Pushing mana into the soles of his feet, Grim combined the physical enhancement he gained from the Breath to push himself up from the ground and shot towards the approaching fist.

*BANG!!*

"Oh wow." The girl raised her eyebrows seeing the mud arm getting whittled down.

'Faster!'

'Faster!!'

'FASTER!!'

*SLASH!!*

*SLASH!!*

*SLASH!!*

Pushing the muscles in his arms to the absolute limit, a look of joy and madness flashed through his eyes.

Swinging his arms wildly, the gray glow on his arms and his swords started to solidify as his grimoire started glowing brightly.

*Slash!*

*Slash!*

*Slash!*

'Faster!! I have to be FASTER!!'

As if hearing his declaration, the light coming from his grimoire intensified as new words started appearing on the [Breath of the Beast] page.

'FASTER!! I'LL GO EVEN FASTER!!'

[Breath of the Beast - 5th Fang: Crazy Cutting]

"ARRRRGHHHHH!!!" Grim screamed as the gray aura around him became solid and transformed into rotating gray blades swirling around his body.

"NICE!!" The girl yelled and gave him a thumbs up.

Having activated a brand new spell, Grim's cutting speed increased as he practically tore through Baro's arm cutting even the smallest bits of mud into nothing.

"A-Amazing..." Neige's eyes lit up as he watched the scene.

"To think you'd actually cut its arm into nothing... Now I really want you Grim." The girl grinned as she watched Baro's arm grow back.

"I'm not done yet!" Grim shouted as he kicked off the cave wall and shot towards the creature's back.

[Crazy Cutting]

Crashing into Baro's back, Grim's blades violently hacked away at it from the inside to the point that he tunneled his way to the front and burst out from its ċhėst.

"WOW WOW WOW!!! You're seriously amazing!!" The girl laughed as the wound slowly closed up.

'Tch, even with my new spell I'm not depleting its mana fast enough.'

"GRIM!!" A voice sounded out from the entrance.

"Huh?"

[Mirror Magic: Reflect Refrain]

*BANG!!*

*BANG!!*

*BANG!!*

Turning back, Grim saw Gauche and Asta running back inside.

"We're here to help!" Asta yelled.

"I'll save you in order to receive Marie's love!" Gauche added.

'Tch, I said I had this.' Grim smiled and turned back to face the monster.

Bringing out his second anti-magic sword, Asta slashed at the monster sent out a flying slash in its direction.

"EAT THIS!!"

*RAAAWWWRR!!!*

The monster screamed before healing up again.

"EH!!!" Asta reacted with surprise after seeing not even that worked.

"COOL COOL COOL!!" The girl cheered. "Hey Asta!! What was that? A long range anti-magic projectile? How did you do it!? How does it work!? AHH! I can't wait to open you and Grim up!!"

'Dammit!!' Gauche grit his teeth. 'The only way to beat this thing is to either deplete its mana or damage it faster than it can regenerate!'

Clenching his fists, Gauche realized that this wasn't an opponent that he could defeat.

'FUCK!!!' He screamed internally remembering that this was the thing that kidnapped Marie.

Before arriving in this area with Asta, both of them had seen Grim tear through its ċhėst and deplete some of its mana.

'Wait a second... I've always used a double of myself to fight... What would happen if I used it on someone else?'

After seeing the damage that both Grim and Asta were able to do to that monster, Gauche had no choice but to acknowledge the two of them.

'Tch, to think that I'd have to rely on someone else...'

Looking into his grimoire, Gauche was surprised to see new words forming on one of his pages.

"ASTA!! GRIM!!" He called out and drew their attention.

*BANG!!*

Dodging another blow from the Baro, both boys turned to look at Gauche who was revealing a small mirror embedded in his left eye.

"What the hel-

[Mirror Magic: Mirror Brigade]

Flashing brightly, 4 new Grim's and Asta's appeared out of thin air.

"WHAT!!" The glasses girl exclaimed in shock.

"GO!!" Gauche yelled.

"ON IT!!" The brigade yelled as they launched themselves towards mud Baro and tore him apart.

'Heh.' Gauche smiled.

Combining Grim's ability to cut the monster's body into nothing so it wasted more mana and Asta's ability to nullify magic, the large amount of Grims caused the monster to expend its mana reserves and allowed the vast number of Asta's to deliver the final blow.
