No one's POV

In a dark, mostly empty room lit by only candles in the four corners, three men stood around the place. Two of them were guards with devil wings on their backs with war axes in hand. The other was a man in his early twenties. He has shoulder-length crimson red hair and blue-green eyes. He wore some kind of armor over his clothes.

This male was none other than the leader of the devils, Sirzechs Lucifer.

He stood at the back of the room behind a desk. All three were staring at the double door exit in front of them, as if expecting someone or something, especially the guards. The guards were visibly nervous, their bodies trembling in fear as they sweat profusely. They had their axes up and aimed at the doors in case something tried to break into the room. However, their leader had an almost blank look on his face, his eyes glued to the doors.

No one said anything, not even a peep. The air was tense and stiff. The only sounds that could be heard were the three's breathing, mostly the two guards breathing heavily through their noses, too afraid to move. Even the creaking in the floor under their feet as they readjust themselves made them tense up and grip their handles tightly, almost breaking them. 

Eventually, that would change. Suddenly, the sound of a muffled shotgun blast was heard behind the door. This causes the guards to gasp silently in horror as they get into fighting stances. As they did, Sirzechs's eyes squint at the door, keeping the blank look on his face.

A second later, they all heard the sound of another shotgun blast along with a scream of pain under it. The sounds of chains clanking around and a thud soon followed by explosions were also heard. After the explosion, the noises lapped over each other as rapid gunshots and screams were added as though a very graphic battle was taking place. One of the guards swore he heard a faint humming under the carnage, but the others didn't hear it.

In the span of a few minutes at most, all the gunshots, explosions, and screams fade. The two guards glanced at each other in dread before looking back to the doors while gulping from the sudden silence outside.

A few more minutes of silence passed. The tension of the stillness made one of the guards quiver and silently sob. The other grit his jaw tightly as he grips his handle harder than before to hide his fear.

Soon, a pair of muffled footsteps were heard approaching the doors. The three stayed in their positions anxiously waiting for someone to walk into the room. However, just as the footsteps were behind the doors, they stopped, confusing everyone. Another pause filled the air while the person just stood in front of the room. After becoming impatient, hesitantly, one of the guards cautiously approached the doors and slowly lifts a hand to grab one of the handles.

Sirzechs caught this in the corner of his eyes and glanced at the guard trying to open the door. "Don't-." He tried to stop him.

Just as the guard turned to look at his leader in confusion, the doors suddenly burst open as something flew into the middle of the room and one of the doors even flew off its hinges and exploded into the wall. The other slammed into the guard's face and sent him stumbling back from the sudden wave of pain.

The other two look down to see what burst into the room. They saw the decapitated corpse of another guard, with both of its devil wings torn off as one was shoved up its rear and the other missing. Not only that but there was a massive gaping hole in its chest, allowing the carpet to be seen through it. This causes blood to ooze out from the wounds and soak into the carpet.

"W-what the-?!" The unharmed guard mutters in horror, while Sirzechs glares at the corpse.

Before the first guard could recover, within the darkness of the hallway the sounds of chains clanking quickly approaching the room was heard and caused everyone to stare just as a blur flew at the guard. He had no time to dodge as the blur stabs and impales him through his chest and armor, cracking it while going through his back. The guard looks down in shock and horror as the other gasps loudly seeing a blade penetrate through the guard's armor.

On the bottom of the blade's handle, chains were connected like a rope.

Just as quickly as the blade was thrown, it was suddenly pulled back violently with the guard being pulled with it. The other tried to reach out to grab him, but it was way too late as he was consumed in the darkness.

"No!" He shouts in horror as he heard his partner scream in terror.

"Get over here!!!" A deep rough voice shouts from the darkness of the hallway, almost sounding demonic.

Almost immediately after, the guard's screams were cut off as a loud thud could be heard, followed by the sound of a chainsaw revving up and cutting through flesh and metal. The guard screamed at the top of his lungs for help but that quickly ended and everything became silent again.

Knowing what happened, the second guard screams in rage as his wings flapped open. He then hovers in the air and quickly flew into the hallway with his axe over his head ready to slice whoever the attacker was. "YOU BASTARD!" He shouts in rage.

Just as he was about to leave the room, a flash of a green helmet's blue lens was visible for a brief second. Afterward, an armored hand grabs the guard's axe by the blade before crushing it in their palm, bewildering him. "H-huh-?!"

A second armored glove grabs his mouth before immediately pulling back and ripping his lower jaw off of his face. The guard's eyes widen as he tries to scream, but his tongue dangles as blood spews out from where his jaw once was, causing him to only gargle now. Then the sound of metal shifting was heard and a blade from the arm suddenly expands and stabs into the guard's right eye and out of the back of his skull, making more blood spew out as the blade pierces through with his eye stabbed into the tip. The person forces the guard to drop to their knee by kicking into his knee with their armored boot while using enough force to snap their knee backward and cause the bone to snap in the other direction. The person then yanks their blade out from the guard's skull and finishes him off by grabbing both sides of his head and violently twisting it so his head was facing Sirzechs on the other side of the room with a loud snap.

Sirzechs saw this execution with a hint of shock on his face as he tried his hardest to not throw up from the graphic scene. 

The person then kicks the guard onto his back as a soft hum was heard. The person steps out of the darkness with a massive metal war hammer in hand as the heads were made of red demonic energy. He lifts his hammer over his helmet before slamming it onto the guard's head, smushing it as his head explodes into millions of pieces onto the carpet, chunks of bones, flesh, and brain matter getting everywhere and the hammer. On said hammer, there was a symbol engraved into it on both sides.

"..." Sirzechs doesn't say anything as he watches the person with the hammer stand up and rest their hammer on their shoulder. Because the person was now in the room, Sirzechs could see who they are, though he already knew.

The person was an extremely tall and muscular male. He wore green armor with brown parts on his left arm, boots, and his abs. He had an extendable blade on his left wrist along with a grenade launcher on his shoulder that was folded onto his back. The lens on his helmet blocked anyone from seeing his face, but that doesn't matter as he had an aura of rage radiating from him, giving him an ominous and frightening look. The only parts that were exposing his skin were his arms, which showed off veins popping out from his skin. On his helmet was the same symbol on his hammer, though this time made from blood.

"...Y/n..." Sirzechs starts, causing the male to grip his handle tighter. "I understand that you're angry with us- the supernatural, and you have every right to be. But this isn't going to bring back those you've lost. You're only spreading innocent blood and causing more grief and pain. How can you explain all the blood you've shed to your wife and-?"

"Fuck. Off." The male in green armor, y/n, demands coldly. He glares at Sirzechs under his helmet and through his lens, under it was clear that he was pissed off. He effortlessly slides his hammer off his shoulder and slams its head onto the ground beside him, snapping the wood under its weight.

He then cracks his knuckles and neck under his armor as he approaches Sirzechs slowly, who starts to sweat in uneasiness. "The only good devils are dead ones..along with the rest of you bastards."

Before Sirzechs could respond, y/n grabs the edge of the desk between them and effortlessly flung it into the wall with a single hand while keeping his enraged eyes on the king. The desk crashes through the wall and explodes upon impact, sending dust flying through their room and the room the desk flew into.

"You let this happen. The pack between the supernatural and my family was broken. And now, you all suffer the consequences." He sneers while continuing to approach Sirzechs, who starts to step back in response. But he was soon met with the wall behind him and was now cornered as the enraged armored male continues to step forward.

After a few more steps, y/n pulls out a pair of claws from his hips that matched his armor. He puts them on his hands before clenching his hands into fists. When he did, two fiery orange claws of energy burst out of his claws and hummed softly.

"We both know that killing me won't solve your problems." Sirzechs states as the male was now within arm's reach.

"It's not about me, "Lucifer"..." Y/n trails off before grabbing Sirzechs by the neck, choking him tightly. The latter tried to grab his hand to get him off, but his grip was too tight to let go. His face started to turn purple from the choking and he tried to gasp for air desperately, but he wasn't able to. Not only that, but the energy blades burned him from a single touch, causing him to pull back in pain. "...It's about sending a message." Y/n finishes. He slams Sirzechs into the wall as he reels his other arm behind himself and above his head and gave him the death glare. Once Sirzechs saw this, the male thrusts his arm forward quickly before everything fades to black.

To be continued...

Hey, everyone. I know that I haven't updated this story in nearly a year and I deeply apologize for that. I never really had time to update this story despite me actually wanting to desperately. But now I want to get some work done for this story.

I'm just going, to be honest with you all; I will most likely not finish this story. HOWEVER, I do have my reason. That being I am quitting Wattpad soon. If you are unaware, I made an announcement saying that I plan on retiring in 2023. And in that time, I will be focusing on two stories, but I want to also update a few unfinished stories that I have a few unpublished chapters left or want to see some more progress on. This is one of them.

While I may not finish this story, I at least have several chapters that I want to release. I actually really like the premise of this story as it's very different than most High School DxD x DOOM crossovers and even HSDxD stories in general that I'd like to see get some more love by me. And I may work on a one-shot spin-off to this if it goes well. I know that because I left this story to collect dust for almost a year, not a lot of people may see this. So I'll need to see how well this does. 

So, yeah. That's my plan for this story. I wanted to make this teaser to say sorry for the wait and that I'm not done yet. Hopefully, I can work on the official first chapter within the next two weeks. I don't know about any other chapter schedule yet as college is starting in a few weeks and I want to work on other stories. But do expect me to continue making a few more chapters soon. 

So, yeah. I hope you all enjoyed the teaser and understand my reasoning for the long pause as well as let me know your thoughts. Despite not planning on finishing this story, I hope you guys can stick with me with the chapters that I do upload. And don't worry, I won't be leaving this story off on a cliffhanger. There will be something coming. Lastly, I hope you all have a wonderful day/night. See ya.
