An Antagonist's Revenge(Remake)

The Hero's Downfall(2)

Beneath the ground, I can perceive the movements of something large and long sliding.
*PSSST!*
A vicious white worm-like monster with a large hole at one end, presumably its mouth, blast out of the sand. The aftermath hurls me away as it gulps Kazuki.

Haha...of course, fate won't sit back and let him die.

Its mouth, filled with sharp teeth from the inner circumference to the tip, is said to consume even a dragon. They are called Deathworms and a single one can destroy an entire city. Additionally, they are mostly attracted by the scent of blood but a Deathworm shouldn't even be here.

The Deathworm then swiftly lunge itself away, seemingly to move away from me.

...

I sigh and leap at the Deathworm throwing a slash of mana. However, it dissipates upon contact with its hard outer shell.

"That didn't work huh...fine," I mumble.

My body appears above the Deathworm with my arms up high, slamming my hand down.

*BAM!!!!*

The wiggling creature's body falls to the ground and lifts tsunamis of sand, a barrier of wind preventing any from touching me.

!

A large deadly purplish beam shoots through the sky vaporising anything in its path. When the spell finishes, nothing is left at my original location.

"Fuck...where did that bastard come from?" An old man with a hunched back says. He wears full black ragged cloth across his wrinkled frail body. Only having a few strands of white at the side of his head and diluted blind pupils, nobody can see at first glance that he is a twentieth-star black magician.

The old man walks to the Deathworm and caresses its exterior. Heaving a sigh of relief, the old man mumbles "Good, the Deathworm isn't dead."

His finger glows in purple and it leaves behind violet carvings of mana in its path. The old man draws random haphazard symbols and runes in the air before it lights up and vanishes.
"The attack will be delayed a few days, some brat came and attacked the Deathworm-"

Suddenly, the old man can see knuckles in front of his face.

*BAMMMM!*

My punch throws the old man back. He enhanced his body before I touched it...

His arm is raised, guarding his face. Part of the cloth was ripped off and revealed his arm bruised by my attack.

"Who are you...?" The old man asks.

"..."

"Not a big talker huh...tell you what, the Blood Order needs your strength. We will grant you anything you want, fame, power?"

...

I ignore all of his questions. From the tenth star onward, a magician can passively produce mana inside their body so removing atmosphere mana is useless; I could only kill Rienni and Ceaser because they were distracted.

But I have one trump card that can instantly end this bastard... I just need him to strike first with his guard down.

Veins appear on the old man's face when I ignore him and walk to the Deathworm. "Are you ignoring me?! How dare a foolish brat!"

The air turns bleak and a reaper materializes behind the old man. "A pity but ignorant fools are not called for."

The reaper swings its scythe aiming for my heart. The scythe slashes across my body like tofu yet no damage was done to me.

Instead, the old man's body splits into two separating his upper torso from his waist.

"Phew...that worked..." I mumble.

I simply rebounded his magic back to the caster. However, if his guard was up he could simply cancel his magic and consecutively launch another to kill me.

Skill Devour activate
------------------------
A rush of Dopamine strikes my body. Intense energy tries to fit itself into my tiny physical vessel. I take a deep breath and form the sixth circle around my heart. Exhaling, shiny blue mist travels with my breath. In addition, the old man had "Mana Outburst" as a skill. Good, I will need this.

I turn to the Deathworm and burrow my hands into its body, pulling out the hard shell.

"GRAAAAAAHHHH!!!!" The Deathworm squeals. 

The tip of my finger glows and it cuts through the creature's skin easily. Yellow blood sprays out with some organs. I punch the mushy lump of meat into a hole and finally see a human's body, pulling that body out it is Kazuki, passed out.

"RAGRHHHHHH!!!" 

"Shut up!" I shout and kick the Deathworm, hurling the Deathworm up in the sky to shortly rolling across the sand. I take a deep breath and pry the majestic sword from his only remaining limb, his left hand.

I nonchalantly cut his hand off, making it levitate in the air as my hand rises. With a clench, Kazuki's limb crushes by the atmosphere into a pulp of mess.

...

"Hah..." I sigh.

Killing Kazuki no longer sends me into ecstasy because I've done it so many times. Yet every time, he is somehow resurrected. That's why I cannot wait for the day his mind is finally broken. With his destroyed and wanted reputation, it will be difficult for him to hide or receive help when he is resurrected. 

Using a single mana sword, I stab his heart and pull out the sword before decapitating him and waiting.

...

...

...

My devour skill isn't activating. Kazuki isn't dead yet, how the fuck is he still alive?

I store his corpse inside my Mana storage as a precaution. This is also where Jade steps in.

I take her out and place her lying on the ground. Repeating the slavery magic I cast on Rias, previously Rienni, a strip of scar appears around Jade's neck.

In addition, I stack a layer of mind control magic.
"You were my close companion that lost touch with me during the war 4 years ago. Your name is now Ema, you were an orphan for as long as you can remember and have extreme short-term memory, leading to gaps in your recollection. You don't think too much about it though." I say.

As an extra coating of defence, I need Jade to stay by my side frequently.

I am not going to die to Kazuki again.
