DXD: The Villainous Devil Signs-in into the Mash-up Anime World

Katerea was right.

The reason she sought out Lucius was to stop his marriage with Sona.

But.

There was a second reason.

That was... to claim Lucius for herself!

To take him, to break him, and to bear his children!

This—was Katerea's true purpose for coming.

During the war between the Old Satans and the New Satans,

the Old Satans had sent many spies into enemy territory.

One of these spies, an old man, managed to send back a final message before failing his mission.

"If you want to defeat the New Satans and reclaim the Satan throne, you must obtain Lucius Leviathan."

"He himself may be useless now, but Katerea, if you conceive his child, you may birth an extraordinarily powerful heir."

"Your child, inheriting his original talent, could be the key to overthrowing the New Satans."

Because of this elder's final words, Katerea could not allow Lucius and Sona to marry!

First, if Lucius and Sona had a child, it might expose the secret of his bloodline.

Second, once married, Lucius would grow closer to the Sitri family and Serafall, making it even more difficult for her to get close.

Thus, the moment she heard that Lucius had received Evil Pieces, Katerea wasted no time in rushing to claim him.

She... had no more time to hesitate!

Previously, Katerea had always been proud and hesitant.

She believed she could handle things on her own.

Why should she need Lucius?

She, Katerea Leviathan, could overthrow the New Satans with her own power!

But as time passed, her confidence crumbled.

She realized that, unlike her great ancestor, she was not a genius.

Even breaking through to Satan-class was proving incredibly difficult.

With no other choice, she resorted to using rare resources to forcibly push herself to Satan-class.

And then... tragedy struck.

After her forced breakthrough, she found that her potential had been completely locked.

She was permanently stuck at low-tier Satan-class.

She would never grow stronger.

Left with no other choice... she had to activate the backup plan.

If she couldn't do it herself, then...

She would start a new account!

Even though she had to accept reality, Katerea remained proud.

Who was she?

And who was Lucius?

A discarded failure!

Even if he had some use, it was only as a breeding tool.

And yet, this tool had dared to strike her face?!

Unforgivable!

Katerea was furious, and the consequences would be severe!

She didn't even realize that her activation of Ophis' "Snake" was not an accident—

Lucius had deliberately triggered it!

With terrifying chaos energy erupting, Katerea pushed back, nearly shattering Seekvaira's defenses.

Seekvaira bit her lip, casting Lucius a guilty glance.

She felt she had failed him.

Even with the Boosted Gift, she could not defeat the enemy before them.

Now, because Lucius had transferred his boosts to her, he could no longer use his Sacred Gear.

She had to protect him at all costs!

"Lucius-kun! I've tried already, and I can't send a message out."

"But... with my increased strength, I've found a weak point in this dimension."

"I'll focus all my power on breaking that weak point. When I do, you have to escape immediately!"

Seekvaira offered a solution—an imperfect solution.

"And what about you?" Lucius asked.

"..."

Seekvaira fell silent.

To create an exit, she needed to hold the weak point open with all her strength.

Naturally, she would not be able to leave with him.

"I'll stay behind to hold off the Old Satan."

"Lucius-kun, your task is to escape and immediately contact Grayfia."

"She has the power to manipulate dimensions. She can reach this place quickly and support me!"

Seekvaira spoke with determination, hoping Lucius would accept her plan.

Lucius, however... refused.

"No, I don't agree."

"If I leave, the Boosted Gift will wear off quickly. Then, you won't be able to hold off Katerea!"

"You must go, Lucius-kun! There's no more time to argue!" Seekvaira shouted in frustration.

As everyone knew, when facing danger together, a man and woman's bond would deepen.

Lucius refusing to leave her behind only made her heart race faster.

Though his decision was illogical, it made her fall for him even more.

Which only made her more annoyed.

"Why must such a perfect Lucius-kun refuse to listen to me?!" Seekvaira inwardly cursed.

Watching her frustration, Lucius smiled to himself.

Time to reel her in.

"Seekvaira, do you trust me?" Lucius asked, his voice steady.

"Trust isn't the issue right now!" Seekvaira snapped.

"No, this is exactly the time for this question."

Saying that, Lucius retrieved a pet collar.

This was why he had provoked Katerea.

To have an excuse to collar Seekvaira.

"Seekvaira, I have a way to deal with Katerea—but I need your full cooperation."

"You have to completely trust me."

"..."

"Fine... I'll try your method, Lucius-kun."

Seekvaira sighed, reluctantly agreeing.

Lucius stepped behind her, holding the collar.

His warm fingers brushed against her soft, white neck.

Seekvaira's entire body trembled.

"Click."

With a soft sound, the collar locked into place.

From this day forward.

Lucius' faction had gained yet another Princess of the Underworld.
