40: Chapter 40

Just as he was thinking, a furious shout suddenly exploded, enveloping the entire villa and piercing their eardrums.

"Red Dragon Emperor, get out here!"

The three people doing morning exercises—Tsubaki Shinra, Tsubaki Shinra, and Reya Kusaka—stiffened simultaneously.

Is someone here to cause trouble for Master again?

I hope it's not like last time.

That great war, with gods, dragon clans, devils... all mixed together in a chaotic brawl—just thinking about it made their backs run cold.

Tsubaki Shinra immediately drew her long sword, scanning the surroundings vigilantly, trying to find where the voice was coming from.

The three of them soon saw a young girl a few years older than them, hovering above the villa.

Her twin tails were fluttering in the wind, her face was quite pretty, and she was dressed in a magical girl outfit that accentuated her curvaceous figure.

But her eyes were full of fire, as if she wanted to tear someone to pieces.

"Sister?!" A startled cry came from behind, filled with shock.

It was Sona.

She stared at the woman in the sky with a look of confusion and shock.

"The President's sister?" Tsubaki Shinra and Reya Kusaka were both stunned.

Master had told them before that the President had a sister named Serafall Leviathan, one of the Four Great Satans of the Underworld and heir to the Sitri Clan.

So that meant this girl in the sky, who didn't look much older than them, was actually a Devil King of the Underworld?

Looking at her outfit again... it was far too different from the image of a Devil King that Tsubaki Shinra and Reya Kusaka had in their minds.

Could it be that Devil Kings of the Underworld were following trends now?

But the problem was, since she was the President's sister, why did she come here with such murderous intent to scold Master?

What kind of grudge could there be between the two of them?

"Serafall."

Luo Yu came out as well, frowning as he looked at the angry face in the sky, his mind churning—when had he ever provoked her?

"Red Dragon Emperor!"

As soon as Serafall saw Luo Yu, it was as if she had finally found a target for her vent.

She didn't offer a single word of explanation.

Her magical power surged violently, and the surrounding temperature plummeted to the bottom.

In no time at all, the entire villa was frozen into a block of ice.

Even the entire area of Kuoh Town was affected, as if it had been dragged into a freezing winter of extreme blizzards.

This originally peaceful little town really didn't have many days of peace.

Sona's expression changed instantly.

Her sister was serious; what on earth could have happened to make her this angry?

She wanted to stop her, but it was already too late.

Butler Izumi also rushed out of the house, looking in shock at the uninvited VIP, wondering why she was at odds with their son-in-law.

"Balance Breaker!"

The appearance of the Boosted Gear on his left hand changed abruptly; the Balance Breaker was activated, and black-red armor instantly covered his entire body, with a pair of pitch-black wings spreading from his back.

His aura soared directly to the peak of the Super Devil level.

If it were the dragon-species form of the Balance Breaker, he could rush directly to the limit of the Super Devil level.

But in humanoid form, he was a step behind.

Although he was one tier lower than the murderous Serafall in the sky, it was enough.

To deal with her, there was no need to raise his combat power to that level.

"...Master."

Luo Yu's current appearance was exactly the one most familiar in Tsubaki Shinra's memory.

"It really is you, Red Dragon Emperor. It was all you pulling the strings behind the scenes!"

Seeing the Boosted Gear, Serafall seemed to confirm something, and her rage grew even fiercer.

She attacked immediately.

With a wave of her magical girl staff, a massive ice sphere capable of crushing the entire villa into fragments smashed fiercely toward Luo Yu.

"This woman is truly willful, not even caring if her attacks hurt others."

Luo Yu frowned, raised his finger, and tapped lightly at the ice sphere.

He only spat out two words.

"Black Water."

A pitch-black giant wave surged out of thin air like a dragon; this was the ability of the Primordial Dragon of Darkness, Apophis—Black Water that devours and corrodes everything.

Because its function overlapped somewhat with the Crimson Emperor Flame, he rarely used this move in battle.

But right now, using Black Water to completely swallow Serafall's attack was the only way to prevent Tsubaki Shinra and the others from being hurt by the aftermath.

As soon as the ice sphere touched the Black Water, it was swallowed up completely in no time, and the Black Water grew even larger, rushing toward Serafall.

"The ability of the Primordial Dragon of Darkness, Apophis!"

Serafall relaxed slightly; she had been a bit impulsive just now, almost dragging little Sona into it.

But seeing the Black Water rushing toward her, she immediately frowned and hurriedly dodged.

"Getting distracted during a fight is not a good habit, Devil King."

Luo Yu had already flashed instantly in front of her, throwing punch after punch, slamming heavily into the sky.

Every punch was wrapped in Crimson Gold Holy Flame.

That was a power that was extremely effective against devils.

Serafall had lived long enough.

She had experienced The Great War, and she had survived the bloody infighting within the devils.

Being able to sit on the throne of a Devil King relied on true ability.

She flipped and flew in the air, casting ice-type magic one after another, every move precise and ruthless.

Luo Yu's attacks were blocked by her one by one, and she countered with a torrent of ice.

The sky completely exploded into chaos.

On one side were rolling heat waves of flame, and on the other, bone-chilling cold.

The two forces collided in mid-air, neither giving way to the other.

Sona stood below, sweating with anxiety.

She couldn't make sense of the situation at all.

Why did her sister suddenly storm into the Human World?

Looking at the situation, it was clearly aimed at Luo Yu.

The two were locked in a fierce battle.

Red light and blue light collided crazily in the air; every impact seemed like it would tear a hole in the sky.

The sky was smashed into black holes, appearing in patches like tattered cloth.

Serafall was indeed a cut above Luo Yu.

But she hadn't expected the three powers Luo Yu possessed—Black Water, Crimson Emperor Flame, and Crimson Gold Holy Flame—to be so troublesome.

Especially that Crimson Gold Holy Flame.

This thing was even more overbearing than holy power; even a devil of her level couldn't withstand it.

When the flames burned over, she felt her body trembling.

That sensation was even more agonizing than the Crimson Emperor Flame.

If it weren't for the fact that the corrosion curse of the Boosted Gear wasn't easy to activate, she probably wouldn't have lasted this long.

Luo Yu didn't want to drag this out any longer.

If it weren't for the fact that she was one of the Four Great Satans of the Underworld, and if she weren't Sona's own sister, he would have wiped her out with one Eternal Paradise move long ago.

However, it wasn't too late to use it now.

"Divine Art, Eternal Paradise!"

Serafall's face turned pale instantly.

She was all too familiar with this move.

During The Great War, the God of the Bible used this move to kill countless devil warriors.

The only reason she survived was pure luck.

"Sister!"

Sona screamed in fear.

Although she wasn't entirely sure how powerful the Eternal Paradise was, she knew that Luo Yu used this move to destroy Hades, God of the Underworld, and even wiped out the entire Underworld with it.

"Second Young Lady, the son-in-law should know his limits."

Butler Izumi quickly soothed her from the side.

No matter how strong the Eldest Young Lady was, it was impossible for her to be stronger than Hades, God of the Underworld.

Serafall gritted her teeth, her face full of defiance.

Even if Luo Yu was strong, he couldn't be an opponent capable of killing a Super Devil, right?

If he really wanted to deal a lethal blow, the son-in-law should have won long ago.

The next scene was exactly as Butler Izumi had said.

A kingdom suddenly condensed over Kuoh Town, vast and magnificent, with a holy aura sweeping down and covering everything.

However, this Eternal Paradise was incomplete, only showing one layer, far inferior to the might of the nine-layered kingdom when he wiped out Hades, God of the Underworld before.

The degree of solidity was also significantly lacking.

But even so, the town residents were dumbfounded, each looking up at this scene that resembled a divine miracle.

The appearance of the Eternal Paradise also alarmed Rias Gremory and Akeno Himejima.

"It's that bastard Luo Yu again!"

Rias Gremory looked annoyed.

Ever since she came to Kuoh Town for training, she hadn't had a single day of peace.

She turned her head to look at Akeno Himejima beside her, who was full of worry and looked like she wanted to break through the window and rush out, and said irritably: "Relax, your little lover won't die. That magical power is from Serafall, Sona's sister; she won't fight to the death like before."

The more Rias Gremory talked, the angrier she got.

"I really don't know what's so good about that bastard, same with you, and Sona too... A few days ago, Sona even came to ask you, her 'love rival', inquiring about what flavors that bastard likes to eat."

"Ara ara…"

Hearing that Luo Yu was fine, Akeno uttered her habitual catchphrase again, smiling and saying: "Rias Gremory, you don't understand; this is the world of adults."

"Akeno, I remember you're a few months younger than me, right?"

Rias Gremory glanced at her sideways.

"That bastard actually looks down on me!"

Serafall looked at the single-layered Eternal Paradise in the sky, feeling severely humiliated.

Her strength was indeed not as good as this bastard's… but she didn't believe she couldn't even break this half-baked Eternal Paradise!

Serafall erupted with all her magical power at once.

The extreme cold aura exploded instantly, freezing ten thousand miles, and the entire sky was frozen solid.

Even the Eternal Paradise summoned by Luo Yu was frozen inside.

But she didn't get to be happy for long.

Luo Yu curled the corner of his mouth and raised his hand gently.

The frozen Eternal Paradise suddenly erupted with terrifying holy power, shattering all the ice with a boom.

Serafall's expression changed drastically.

Before she could react, the Eternal Paradise crashed down directly, pressing heavily onto the ground.

Boom—she was firmly pinned down by the shrunk Eternal Paradise, lying on the ground in a wretched state, unable to move even a finger.

Serafall desperately tried to mobilize her magical power, but let alone moving it away, she couldn't even shift it by a centimeter.

"Serafall, I don't recall offending you, do I?"

Luo Yu deactivated the Balance Breaker and the Boosted Gear armor, landing steadily in front of the villa.

He looked down at Serafall, who was pressed under the ruins, the other party glaring at him with a face full of anger, and he felt somewhat puzzled.

He carefully thought about the grudges between himself and the Underworld.

It was nothing more than messing with devil reincarnation technology, and then slaughtering a few pure-blooded devils.

What did these things have to do with Serafall?

"Red Dragon Emperor, you bastard, how dare you play innocent!"

Serafall cursed, her voice filled with unspeakable grievance.

"Don't you know what you've done? You really are a sinister villain!"

Seeing that she still had the energy to yell, Sona finally felt a bit more at ease.

She didn't want Luo Yu to get hurt, but she was also afraid of her sister getting injured.

"Sister…"

"Little Sona, your sister is too useless."

Seeing her sister, Serafall's expression suddenly became pitiful.

"I couldn't even save you from that hateful man."

Luo Yu stood to the side, speechless.

It was as if he had done something wrong.

It was clearly this willful and reckless Devil King young lady who came to provoke him herself, and he had already been merciful enough by not beating her to death like he did his other mortal enemies.

"Luo Yu, release my sister first."

Sona pleaded.

Luo Yu didn't say any more nonsense and directly dispelled the Eternal Paradise pressing down on Serafall.
