Chapter 22: The Old Demon King's Counterattack

On the other side.

As soon as Lucien closed the door to the student council room, he heard the system's notification.

[Ding!~]

[Congratulations, host! You have triggered a Villain Check-in!]

[Check-in Level: Colorful]

[Check-in Type: Stage Event Check-in.]

[Check-in Event: The Old Demon King's Conquest of the Current Demon King.]

[Requirement: Take possession of Serafall Leviathan and Sona Sitri's hearts and bodies, marry both of them, and succeed the Demon King's throne, completing the Old Demon King's glorious counterattack against the Current Demon King.

Note: Sona is silver, Serafall is gold. Marrying both and succeeding the Demon King's throne will reward you with a Colorful-level reward.]

...

"As expected of a Colorful-level check-in. The difficulty isn't low."

"However, even without this check-in task, this is a goal I must achieve."

"Hmph~ Did they think they could use me as a tool and then just run away?"

Lucien had always been very concerned about the phrase in Serafall's profile: "Her bloodline has been purified to its limit, resulting in an evolution."

Although there was no concrete evidence, Serafall had likely benefited from his influence to become stronger than she was in the original storyline!

...

Just as Lucien triggered Sona's task, the student council door behind him suddenly swung open.

"Lucien!"

Sona rushed out of the student council room and hugged Lucien tightly!

"Lucien, you just said you were confident you could defeat my sister, right?"

"That's correct."

"Then, is it you or your Agumon who is confident in defeating my sister?"

Sona had found the loophole. Lucien hadn't mentioned anything about Agumon earlier!

The fact that Lucien dared to say this meant that his own strength was definitely not just what he had shown so far!

"Is it me or Agumon who's confident..."

"Both Agumon and I are confident in defeating Serafall," Lucien answered truthfully.

"Good!"

"Then, Lucien, please show me that confidence!" Sona's eyes were filled with determination.

She wanted to see just how far Lucien could go!

...

A few minutes later, on a grassy field.

Tsubaki Shinra adjusted her glasses as she watched Sona and Lucien facing each other.

Sona, as her "King," had keenly noticed that Lucien had been hiding his true strength.

However, a question arose.

If he had been hiding his strength before, why was he revealing it now?

Had he achieved his goal? Was there no longer any need to hide?

What exactly was Lucien's goal?

Was it to break off the engagement with Sona? Or to marry Rias?

Lucien: My goal? Of course, it's to get engaged to Rias! Getting engaged to Rias and getting engaged to Sona are two completely different things. Getting engaged to Rias would allow me to freely use my power. Getting engaged to Sona would mean I couldn't show strength greater than hers.

As Tsubaki pondered this, she observed the battle between Lucien and Sona.

...

"Sona, if I win, I want you to become my ally and help me change the system of the Underworld."

Lucien raised his left hand and spoke slowly.

"No problem, Lucien. Our dreams don't conflict."

"Moreover, I would be happy to witness you changing the Underworld."

Sona nodded, preparing herself.

The next moment.

[Boost!]

The Red Dragon Emperor's Gauntlet appeared!

Crimson spiritual energy erupted!

The green jewel shone with dazzling light!

[Welsh Dragon Balance Breaker!]

[Balance Breaker! — 'Red Dragon Emperor's Armor'! (Boosted Gear Scale Mail)]

The crimson dragon armor instantly materialized!

...

"Such powerful spiritual energy!"

Sona's eyes widened, ripples of shock appearing in her gaze.

Such immense dragon spiritual energy had surpassed that of a high-class devil, reaching the level of a Ultimate-class devil!

Was this what Lucien had been hiding!?

"Lucien, this is..."

Sona swallowed hard and asked.

"This is the Balance Breaker form of the Longinus, 'Boosted Gear,'" Lucien replied calmly.

"A... Longinus!?"

Sona couldn't hide her astonishment.

After regaining her composure, Sona couldn't help but smile.

Lucien was truly Lucien. He had thought of using a Sacred Gear to strengthen himself before she had!

While she was still in the planning stages, Lucien had already put it into practice and even unlocked the Balance Breaker of his Sacred Gear!

He was truly the Lucien she admired!

"Haahhh!~~"

Sona raised her hands, and powerful water magic surged.

The Sitri family's exclusive magic circle quickly formed.

A torrent of water capable of crushing mountains shot forward!

There was no resistance.

The water torrent struck the Red Dragon Emperor's Armor head-on!

"Zzzzz!~"

Lucien stood firm, allowing Sona's water to wash over the armor.

[Name: Lucien (♂)]

[Level: LV184 = LV99 + 85 (High-tier Ultimate-class Devil)]

[Attribute Evaluation]

[Note: Strength within the same level.]

[Strength: B]

[Speed: B]

[Magic: B+]

[Physical Defense: B]

[Martial Arts/Magic Proficiency: C]

[Sacred Gear/Bloodline Ability: SS+]

[Comprehensive Evaluation: B-class Ultimate-class Devil]

[Overall Evaluation: Slightly above average.]

Since he needed to be compared to opponents of the same level, Lucien's attributes had dropped somewhat.

However, even so, Lucien had genuinely reached the level of a Ultimate-class devil!

In fact, he was among the best of them!

.....

"Haahhh!~~"

Sona didn't give up, using the same giant water sphere she had used against Agumon.

"Whoosh!~"

The massive water sphere carved out a hundred-meter-deep crater!

But in the center of the crater, Lucien remained unharmed!

Sona's attack was powerful enough to alter the terrain, but it still couldn't harm Lucien!

Because, in the end, water was just water.

And Lucien was a rock! Their mass and density were completely mismatched!

The Red Dragon Emperor's Armor had incredible defensive capabilities, able to block most attacks from opponents of the same level.

Let alone an opponent one level lower.

...

Over the next few minutes.

Tsubaki calmly watched as Sona unleashed various attacks.

Soon, after using all her techniques, Sona raised a hand.

"Lucien, I admit defeat."

Losing to a Longinus user who had unlocked Balance Breaker was nothing to be ashamed of.

.....

Back in the student council room.

Soon, Lucien and the others returned to the student council room.

"Lucien, the engagement has been canceled."

"From now on, we are no longer engaged."

Before the battle began, Sona had torn up the engagement contract in front of Lucien.

Now, she and Lucien were no longer engaged.

But... she felt that the distance between her and Lucien had grown closer.

She understood Lucien better now, and the distance between their hearts had shrunk significantly.

"Phew~"

Sona let out a long sigh, stood up, and walked over to Lucien, her eyes filled with determination.

"As a parting gift, Lucien, can you kiss me?"

As she spoke, Sona's face turned an unprecedented shade of red, and her slender, pale hands unconsciously intertwined.

For a proud devil princess like Sona, confessing and saying such things had taken all her courage.

"..."

Lucien didn't speak, only nodding silently.

"..."

Seeing Lucien nod, Sona's lips curled into a smile.

After mentally preparing herself, Sona slowly sat on Lucien's lap, holding his hands.

For devils, strength was the best aphrodisiac.

Moreover, even before knowing Lucien's true strength, Sona had already been unable to resist.

"Sona..."

Lucien placed one hand on Sona's slender waist, moving upward, while the other hand reached for the hem of her skirt.

Men and women were different. When intimate, men often couldn't control their hands.

"Lucien, you're such a bad person."

Sona felt Lucien's movements, her heart racing like never before, her body producing estrogen in preparation for bearing offspring.

She knew that if this continued, she wouldn't be able to hold back.

By then, it wouldn't just be a kiss.

But...

From the beginning, she hadn't planned to hold back.

Lucien's golden eyes met Sona's pink ones.

The next moment, the distance between their faces narrowed to just a few centimeters.

Their gazes intertwined, tender as water.

Their bloodlines merged, fierce as fire.

On the sofa.

By the bookshelf.

On the student council desk.

Lucien savored the taste of the Underworld's princess.

[Ding~]

[Detected that host is seizing destiny. High-dimensional Succubus Bloodline activated.]

[Ding!~]

[Congratulations, host! You have obtained: Pure-blooded Sitri Devil Bloodline (unawakened or mutated).]

[Host's level has increased by 10 levels. Current level: 109 (Low-tier High-class Devil).]

"The High-dimensional Succubus Bloodline can also increase levels?"

"Then why didn't it work when I was with Hayasaka Nao..."

[Ding!]

[Hayasaka Nao's destiny was absorbed by the host during childhood.]

[In addition to absorbing destiny and enhancing one's cheat-like abilities, the High-dimensional Succubus Bloodline can also replicate and enhance bloodlines.]

[The more connections made with the bloodline's source, the greater the enhancement for both parties.]

"So that's how it is. As expected of the High-dimensional Succubus Bloodline."

Lucien narrowed his eyes. Getting intimate with anime heroines not only gave him experience but also strengthened his foundation. Was this encouraging him to conquer the entire Underworld?

Indeed, the High-dimensional Succubus Bloodline's effects weren't just about attracting the opposite sex.

[Ding!~]

[Congratulations, host! You have completed the Villain Check-in!]

[Check-in Level: Silver]

[Check-in Type: Stage Event Check-in.]

[Check-in Event: The Old Demon King's Conquest of the Current Demon King (Stage 1).]

[Congratulations, host! You have received the reward: Divine Authority — Silver Arm That Tears Apart.]

[Silver Arm That Tears Apart: A divine authority from the god Nuada. When activated, the flesh hand transforms into a silver metal hand, enveloping a weapon with immense magical power, granting it the miraculous ability to split the earth, alter terrain, and part the seas.

In theory, using the Silver Arm That Tears Apart, one can wield a demonic sword capable of cutting through anything. The object doesn't need to be a sword; even a toothpick or a branch can become a demonic sword.]

.....

Although he had gained a powerful new ability, Lucien didn't pay too much attention to the system's reward.

Because he was busy dealing with Sona.

Sona was a formidable opponent.

Although both Sona and Hayasaka Nao were high-class devils, the physical differences between a reincarnated devil and a pure-blooded devil were vast.

How could a recently reincarnated devil compare to a high-class devil who had been nurtured by a pure-blooded devil's bloodline for over a decade?

...

And so, today, both Lucien and Sona skipped class.

Noon.

Student council room.

Sona sat on Lucien's lap, her hands clasped with his.

The bespectacled girl gently bit her alluring cherry lips, her lips curving into a sweet smile, her dimples showing.

Feeling Lucien's pulse, Sona's rhythm gradually synchronized with his.

Before long, Sona felt a new kind of energy surge.

This energy felt both familiar and foreign.

It somewhat resembled Leviathan's magic, but overall, the similarity was only slight.

After a morning together, Sona's hair was disheveled, and her usually noble and cold face was now flushed and radiant.

The princess of the Underworld quietly gazed at the young man beneath her, her watery pink eyes filled with submission and satisfaction.

Sona was very satisfied.

Mentally, physically, and even in her lower abdomen, she was so satisfied that she felt like she might overflow.

"Lucien, do you know why I did this?" Sona asked softly.

"Because..."

Before Lucien could finish, Sona answered first.

"Because I no longer plan to marry anyone else, so maintaining my chastity before marriage no longer has any meaning."

"..."

Lucien didn't speak, only reaching out to stroke Sona's sweat-dampened black hair.

"Lucien, I did this to give you more pressure too~"

"Lucien, you must come to the Sitri family and marry me."

"Otherwise, I'll never be able to marry anyone else," Sona pouted, reminding him.

"I know. What I say, I will achieve."

Lucien smiled lightly.

Although he felt no pressure, he would indeed strive to fulfill his promise.

What pressure could Lucien have?

As the heir of the old Leviathan, he had conquered the sister of the current Leviathan. Such a thing would only fill him with a sense of conquest and immense satisfaction.

Rather than pressure, what Lucien feared was danger.

Compared to the pressure of being intimate with the princess of the Underworld, the potential dangers of lacking strength and influence were what truly concerned Lucien.

Now.

Anyone who wanted to move against him would have to consider Serafall, who stood behind Sona.

So, compared to when he was thinking of how to escape, the current Lucien truly felt no pressure.

"Mm, Lucien, I believe in you."

Hearing Lucien's promise, Sona swayed her hips, expressing her approval.
