Strongest in DxD - Chapter 14

And that was what was really worrying Sirzechs.

The Crimson Demon King darted towards the direction that Ren's house was and when he got there he saw that it was a completely normal house, he couldn't even feel anything inside.

All this due to a spell by Ren that prevented anyone from sensing something happening in the house and also prevented anyone from teleporting into the house, the exception of Grayfia was that Ren allowed it.

Sirzechs prepared to use his [Power of Destruction] and destroy the house but stopped when he felt his wife's magical power in the distance.

Without even thinking Sirzechs spread his twelve wings and darted towards where his wife's energy was.

...

...

Sirzechs fired as he flew at incredible speed towards where he felt his wife's power.

Sirzechs stopped when he felt the source of where Grayfia's power lay and looked around.

He was in a large forest with several mountains and lakes around, but no sign of his wife.

When Sirzechs prepared to leave there but stopped when he felt a supernatural feeling pass through him and the space around him change.

Looking around he saw that everything around him seemed to have changed, not the scenery but it looked like something was different, on the horizon a purple mist was formed preventing him from seeing ahead.

Sirzechs did not consider himself an expert on Sacred Gear, which he assumed was this mist as he did not know of any magic capable of moving him into an artificial dimension.

So since he wasn't a Sacred Gear expert like Azazel, Sirzechs still had centuries to live and so he saw a lot.

And he only knew one Sacred Gear capable of moving him into an artificial dimension and it was probably a Longinus and among the thirteen there was only one he knew had that power.

"That power? [Lost Dimension]?" questioned Sirzechs to himself.

"As expected of the Crimson Satan, he recognized my Longinus just by looking at her," said a voice that caught Sirzechs' attention.

Sirzechs quickly turned towards a part of the mist that opened revealing a handsome young man with a structured face and wearing a white t-shirt along with pants, sneakers and a black blouse on his body and he had messy black hair and pale blue eyes.

Sirzechs instantly recognized that he was a human, but what baffled Sirzechs most was the power he emanated.

It was definitely God-class, and that should have been impossible for a human.

"Are you Ren Katsuo?!" asks Sirzechs angrily in his voice.

Faced with the rage and venom that the Crimson Satan put into speaking his name Ren simply smiles.

"Exactly, my name is Ren Katsuo, and welcome Sirzechs Lucifer to my Balance Breaker with Longinus [Dimension Lost]; [Heavenly Dimension of the Gods]" said Ren calmly as he smiled.

Heavenly Dimension of the Gods also known as the Heavenly Dimension of the Gods is Ren's subspecies Balance Breaker with Longinus [Dimension Lost], which allows Ren to convert the mist into a barrier to trap his opponents in a different space. The barrier can be molded in multiple locations to allow the user's allies to more easily navigate the alternate dimension and it can be infused with various effects. The Ren subspecies also gives Ren the ability to freely manipulate space and even time allowing hours inside to be seconds in the real world. His main ability is to fully manipulate space functioning as a mix of Trafalgar Law's One Piece Ope Ope no Mi and Kakashi and Obito's Kamui.

Sirzechs realized that the situation was a bit complicated, regardless of whether he was a human a Longinus user shouldn't be underestimated.

"Where's Grayfia?" asks Sirzechs seriously about his wife.

Ren simply gives a mysterious smile: "You shouldn't worry about her, but to answer that, she's in a good place right now" said Ren with a smile that irritated Sirzechs.

Feeling his anger peak, the Crimson Demon King realized that talking to Ren was futile, so he would go for the only option left.

He would kill him.

Slowly an immense crimson aura engulfs Sirzechs' body with such pressure and power that it makes the entire dimensional barrier tremble.

Sirzechs' aura began to disintegrate everything that approached him as his [Power of Destruction] manifested itself out of his body.

Ren was not intimidated when an immense black aura, as if it were the darkness itself, emerged from the reincarnated human's body causing everything nearby to be immense in darkness.

It was a darkness that devoured everything around it, not even sunlight was able to penetrate the darkness that emerged from Ren's body, and even Sirzechs' [Power of Destruction] was completely absorbed and negated.

If Sirzechs' aura was "Destruction" itself, Ren's was "Darkness" itself that devoured everything that approached without exception.

Sirzechs was totally baffled that such a dark and evil aura was coming from a human, it should be impossible for someone to possess such a dark aura.

"What is it ...?! It's... Magic power...! It's very different... I've never felt anything like this... It's not just the strength or the size of it... There's a fundamental difference. It's so thick, so dense, that it doesn't even feel like magical power. It's almost like there's an ocean falling on me…" thought Sirzechs, perplexed by this.

With that Sirzechs had decided, the being in front of him was not only a danger to him and his family, but also a danger to the underworld itself.

And like Maou Lucifer, Sirzechs could not allow a being like him to live.

And to win he had only one choice.

Wordlessly Sirzechs dropped his armor, allowing the pieces of metal to fall from his body to the ground.

His robes followed, revealing his bare upper body.

With those out of the way, Sirzechs took a deep breath…and drew the power out of him, just waiting to break free.

The world itself shuddered and then seemed to scream in terror as Sirzechs' aura grew larger and larger.

In an instant Sirzechs was engulfed in a cocoon of deep crimson, sending shockwaves of raw power reverberating not just across the battlefield, but across the territory of the barrier, and perhaps even beyond.

It would not be surprising if even humans, generally oblivious to events in the supernatural world, were able to feel them with full force.

An entire ocean seemed to have appeared above Ren along the entire battlefield.

A loud crack caught his attention, and he looked back into the eye of that storm of pure power.

The cocoon began to open, red light coming out of the opening, filling the forest with indescribable energy from another world.

Then, with a resounding sound of breaking glass and a blinding flash of red light, the cocoon was ripped open, sending out a massive shock wave that tore down forests and destroyed mountains with its mere presence.
