I, The System Maker

In an instant, Fate weakened the protective clothing and armor on her body to its thinnest, then—

"Sonic Move!"

Combined with Blade Form, Fate turned into a golden lightning bolt, darting around the battlefield.

"Jet Zamber!"

In a flash, golden slashes filled Serafleur's vision. Countless spears and ice orbs were sliced in half like watermelons under Fate's swings. Then, these bisected ice orbs and ice spears fell, gouging out massive craters in the ground.

"Amazing! Is this form focused on speed? Hmm?"

Suddenly, Serafleur found her hands and feet bound within the space.

"Lightning Bind!"

"Chain Bind!"

The restraints set by Nanoha and Fate together were something even Serafleur couldn't break free from quickly.

"This restraint is a bit troublesome!" Serafleur couldn't help but frown. The main issue was that brute force alone was insufficient to break free.

You see, countless chains extended from the magic circles beneath Yuno and Elf's feet, binding them tightly.

With the combined restraint magic of four people, Serafleur was temporarily helpless.

The next moment, a dazzling cherry-blossom glow erupted from the sky, drawing Serafleur's gaze upwards.

Nanoha, now mid-air, wore an excited smile. She raised her staff with her left hand, and a massive cherry-blossom magic circle began to form before her. Nanoha's mental energy continuously extracted magical power from the air, with dense, visible points of magical light streaking as they were absorbed into the magic sphere before her.

Finally, the magic sphere, about two and a half times Nanoha's size, was fully gathered in the air, floating steadily in front of her. Nanoha couldn't help but show a hint of surprise on her face.

Nanoha's technique gathered all the magical power on the battlefield, which also contained Serafleur's magical power.

This magical power was more exaggerated than any Nanoha had gathered before…

"This magical power has actually touched the threshold of a Demon Lord level…" Serafleur was driven to distraction.

Is the level jump too much? Your normal state is only at the level of a high-ranking demon, but your maximum burst can touch the threshold of a Demon Lord, a jump of two whole levels. Are you cheating?!

Of course, if Nanoha could hear Serafleur's thoughts, she would surely say, "Yes, I am cheating!"

"Starlight—" Nanoha coldly uttered two words, the incantation for activating the magic. She pointed her staff at the magic sphere before her: "—Breaker!!!!!"

A cherry-red trajectory shot out from the center of the magic circle. Immediately after, magical power as vast as the ocean surged along that trajectory, carrying an aura that seemed capable of destroying everything, covering the area where Serafleur was.

"Sister!" Asuna cried out anxiously.

Serafleur, with a wry smile, was silently engulfed by this magic cannon.

At this very moment, in the Underworld, Lucifer Demon Lord—Sazex frowned, his gaze fixed on the Sidi territory.

"An unfamiliar Demon Lord-level aura, is it from Serafleur's side? It seems something has happened…"

Muttering to himself, Sazex headed towards the Sidi territory.

Chapter 66: Serafleur: Magical Girls are Invincible! ()

"So amazing, so amazing, so amazing!!!"

At this moment, Serafleur was entangled with Nanoha and Fate, her face filled with excitement.

Nanoha and Fate looked uncomfortably at Serafleur fumbling all over them, even trying to examine Raising Heart and Lightning Axe. The two artificial intelligences were so scared they hid inside Nanoha and Fate's clothes…

Asuna sighed as she looked at Nanoha and Fate, a hint of sympathy appearing on her face.

Her sister's clinginess was something only she, as her sister, was qualified to comment on.

Whenever she had to return home in the past, Asuna's biggest headache was always dealing with her sister.

Not only that, but every time there was a parent-teacher conference, she also dreaded her sister coming to school.

This was because their parents weren't interested in her school affairs. After all, they were demons, so how could they be like her, who was still serving as student council president and was so responsible? Therefore, her sister usually attended parent-teacher conferences.

Although her sister was responsible for diplomatic issues concerning demons, she always made time for her younger sister's affairs whenever possible. This was Serafleur's love for her sister.

However, this love was too overwhelming. Every time Serafleur came to school, Asuna felt like crying.

She was too clingy, so clingy that it felt like everything she had built up at school would be ruined.

"As expected of Magical Girls! Magical Girls are invincible! Hey, hey, hey… What's the deal with your transformation? Can you teach me? I'll help you with anything you need, as long as you teach me how to become a Magical Girl! That's my only request, please…"

Nanoha and Fate had underestimated Serafleur's desire to become a Magical Girl. After exchanging glances, they couldn't help but give a wry smile. You want to be a Magical Girl? There's nothing we can do about that… We're not exactly experts in manufacturing magical devices…

Or perhaps Serafleur should study Raising Heart and Lightning Axe? Nanoha and Fate rejected the idea after just a moment's thought.

Who knows what you might do to our Raising Heart and Lightning Axe… We don't know you well enough!

However, after seeing Serafleur like this, Nanoha and Fate felt that Chu Chen's words made a lot of sense…

She really is a Magical Girl fanatic… Nanoha and Fate felt a sense of helplessness.

"Um… we don't have any other way either. The reason we can transform is actually thanks to the power of our magical devices!"

If she threw away her magical device, Nanoha wouldn't be able to transform either… After all, it was equivalent to a transformation device…

"Oh, right, I see. That magical device is like your transformation device. I guess I need a Magical Girl transformation device too… Do you have anything like that for sale? I can pay for it! No matter the price!"

Human world currency wasn't a big problem for Serafleur…

If there was something like this for sale in the human world, she definitely wouldn't refuse it! Even if it cost a lot of money!

Seeing the troubled expressions on Nanoha and Fate's faces, Serafleur knew it was probably hopeless, but—

"Or you could lend me your magical devices. I can have someone research them!"

Serafleur intended to take them to her world's research fanatic, Achuca Beelzebub, for study.

In Serafleur's memory, Achuca was the only one she knew who was skilled at research.

"This..." Nanoha and Fate exchanged glances, unsure how to answer.

They weren't so open-minded as to hand over their magical devices to someone they had only just met.

"That's enough, sister... Can't you see your enthusiasm is a bit overwhelming for them? No matter how strong they are, they still look like children in elementary school..." Asuna could tell at a glance that they were still elementary school children.

Although the fact that elementary schoolers possessed such combat power dealt a severe blow to Asuna, through Serafleur's conversation with them, Asuna also realized that the temperament of these two girls hadn't matured much.

So, as Nanoha and Fate wore expressions of utter bewilderment, Asuna quietly shielded them behind her.

This also made Nanoha and Fate breathe a sigh of relief, finally escaping the situation.

"Asuna-chan! How can you say that! I'm just welcoming our guests..."

Nanoha and Fate fell silent. Does your family beat up guests before researching their weapons?

Yuno and Elf also breathed a sigh of relief and quietly followed Nanoha and Fate.

"By the way, how did you two end up at our family's base?"

Originally, Asuna thought they were intruders, but seeing the state of these two children now, Asuna dismissed that idea. What could these two children do? Although they were strong, with the Four Great Demon Lords in the Underworld, these two children couldn't stir up any significant trouble, let alone with the Leviathan Demon Lord from the Sidy family.

Serafleur also looked at Nanoha and Fate with curiosity. She was very intrigued by them.

"U-um... Actually, we're magical girls from another world..."

Nanoha hesitated for a moment, then realized she was an undocumented resident in this world. If they wanted to investigate, they could find out her origins instantly, so she decided to state her origins directly...

However, the moment Nanoha uttered these words, an extremely majestic voice suddenly rang out.

"People from another world!"

Instantly, Serafleur's eyes lit up, and she quickly looked in the direction of the voice.

"Yo! Sazex-chan! Why are you here too?"

"With such a huge commotion from your fight, how could I not notice? You can fight, but can you keep the noise down a bit?"

Sazex was speechless, which made Serafleur chuckle sheepishly.

Rolling her eyes, Sazex decided not to bother with Serafleur and focused his gaze on Nanoha and Fate.

As an Over-Regressor, Sazex could naturally sense the immense magical power within Nanoha and Fate... Well, for humans, possessing such power at this age was indeed exceptionally gifted, and they could even unleash Demon Lord-level combat power.

Sazex had never seen a human with this level of combat capability at this age before.

"You just said you're from another world, is that true?"

Sazex was more concerned about this question now.

If people from another world already possessed the strength to cross dimensions, then Sazex's concern was understandable.

"This..." Before Nanoha and Fate could speak, Chu Chen's voice rang out, making their eyes light up.

"Lord Lucifer Demon Lord, could you please not trouble my children here?"

Chapter 67 Chu Chen: I'm helping you out of a tight spot, and you want me to wear a dress?!

"I'm sorry, Chu Chen-niichan, for blurting out our identities like that!"

Nanoha looked at Chu Chen with a face full of guilt, and a hint of remorse also appeared in Fate's eyes.

For them, their first mission had turned out like this, and they felt like they had messed up this time.

In response, Chu Chen waved his hand, not taking the matter to heart.

"Don't worry, it doesn't matter whether you say it or not. There are no strict regulations regarding this here! Besides, I really didn't anticipate this random teleportation issue. Who knew it would send you directly to a place like this!"

Chu Chen considered it an accident. Regardless, Nanoha and Fate being undocumented was beyond doubt.

Nanoha and Fate were completely unfamiliar with this world. If they were to fabricate a lie in this regard, they might arouse Sazex's suspicion. Therefore, rather than fabricating a lie to conceal something from a Lucifer Demon Lord, it was better to tell the truth.

No matter how powerful Nanoha and Fate were, they were still nine-year-old children...

Of course, even if Sazex suspected something, as an Over-Regressor, he wouldn't hold it against nine-year-old children. However, house arrest and surveillance would certainly be involved. He was a Demon Lord of the Underworld, no matter how amiable he seemed usually, a Demon Lord must have ruthless methods! Therefore, Nanoha and Fate's approach was the most suitable...

Besides, even if it wasn't suitable, Chu Chen would never blame the two children, Nanoha and Fate.

"Is it really okay?" Fate looked at Chu Chen with concern, worried that they had caused trouble.

In response, Chu Chen simply chuckled and slowly walked up to the red-haired Demon Lord before him—Sazex.

"My name is Chu Chen. Please take care of me, Lord Lucifer Demon Lord of the Underworld..."

"People from another world?" Although his tone was questioning, Sazex somewhat confirmed their identity.

He could feel that the person before him possessed an astonishing amount of magical power, which even surprised him to some extent.

With such immense magical power, it was impossible for him not to have heard of this person in this world, yet Sazex had never heard this name before. He hadn't even heard descriptions of Chu Chen's appearance.

If Chu Chen was from another world, it would be normal for him not to have made a name for himself in this one.

In this world of DXD, there were legends of people from other worlds, like the EXE from next door. Furthermore, there was someone named Lizevim who was solely focused on invading other worlds, so Sazex was aware of other worlds.

He just hadn't expected any other world to invade, as their own world's internal conflicts were already chaotic enough.

Now that someone from another world had actually appeared, Sazex immediately took it seriously.

He had to figure out the other party's intentions...

"Nanoha, Fate, and I are indeed from another world. Rest assured, Lucifer Demon Lord, I've only come to this world to experience the mysteries of different worlds, not to invade. Besides, have you ever seen an invader bring children along?" Chu Chen said, his gaze unintentionally sweeping over Nanoha and Fate beside him.

Sazex glanced at Nanoha and Fate. His judgment in this regard was not wrong.

He didn't feel any malice from Chu Chen, but the other party might also be trying to test the combat strength of this world. In any case, he would be cautious during this period...

"Since that's the case, how long do you plan to stay in the Underworld? If you need anything, I can arrange for a guide or something!"

As the saying goes, one shouldn't hit a smiling person. Sazex wasn't the type to attack without a word, so he decided to observe first!

"I might stay in the Underworld for a while, and then I'll head to the human world. During this time, I'll trouble Leviathan to act as a guide. Besides, Leviathan has already fought my two younger sisters, so they're acquainted..." Chu Chen said, his gaze falling on Serafleur. At the same time—

A card appeared in Chu Chen's hand. Under Serafleur's curious gaze, he waved it in front of her.

"This card is a random Magical Girl Transformation Card. I can transform into any Magical Girl to fight, and during the transformation, I can possess all of their abilities and strength. I can offer this as payment!"

"Really?" Serafleur's eyes lit up, and she immediately reached out to grab the Magical Girl card in Chu Chen's hand.

But unfortunately, Chu Chen quickly put the card away, and Serafleur couldn't help but feel a hint of disappointment.

"Then I'll trouble you, Serafleur. Please show them around the Underworld..."

"Yes, yes! Just leave this to me! Sazex-chan, you go ahead and be busy!"

Serafleur understood Sazex's intentions. She hadn't let her hobbies cloud her judgment.
