Serafulu: Magical girls are invincible! ( ) / Chu Chen: I helped you out, and you want me to cross-dress?! ( )

In an instant, Fate thinned the protective suit and armor on her body to their lightest state, then—

"Sonic Move!"

Sonic Move combined with Blade Form, and Fate herself seemed to turn into a streak of golden lightning, darting all across the battlefield.

"Jet Zamber!"

In the blink of an eye, golden slashes filled Serafleur's vision. Countless spears and ice balls were sliced apart by Fate as easily as watermelons, each one split cleanly in two. The halved ice balls and ice spears then crashed down, blasting huge craters into the ground.

"So amazing! Is this form focused on speed? Hm?"

Suddenly, Serafleur discovered that her hands and feet had been directly bound within this space.

"Lightning Bind!"

"Chain Bind!"

The restraints set up jointly by Nanoha and Fate were something even Serafleur could not break free from in a short time.

"This restraint is a little troublesome!" Serafleur could not help frowning. The main issue was that brute force alone would not easily break it.

Look, even the Magic Circles beneath Yuuno and Arf's feet had extended countless chains, binding her tightly.

Faced with the restraint magic created by all four of them together, Serafleur had no solution for the moment.

The next moment, dazzling cherry-colored radiance burst forth from the sky, making Serafleur look upward.

Nanoha hovered in midair with an excited smile on her face. She raised her staff in her left hand, and a huge cherry-colored Magic Circle formed before her. Her mental power continuously refined magical power from the air, and dense, visible particles of magical power streaked with light as they were absorbed into the sphere of magic before her.

At last, the magic sphere in the air, roughly two and a half times Nanoha's size, had finished gathering and floated steadily before her. A trace of surprise rose on Nanoha's face as well.

Nanoha's move gathered all the magical power on the battlefield, including Serafleur's own magic.

The amount of magical power was even more outrageous than all the magic Nanoha had gathered before...

"This magical power has actually reached the threshold of Demon Lord class..." Serafleur could not help feeling exasperated.

Wasn't the gap between their levels far too absurd? In their normal state, they were only at the level of High-class Devils, yet their greatest burst could touch the threshold of Demon Lord class. They had directly skipped two ranks. Were they cheating?

Of course, if Nanoha heard that thought, she would definitely say, I really am cheating!

"Starlight—" Nanoha coldly spoke the two words, the activation chant for the magic, then pointed her staff at the magic sphere before her. "—Breaker!!!!!!!"

A cherry-red trajectory shot straight out from the center of the Magic Circle. Immediately afterward, surging magical power like a raging sea poured along that line, carrying an aura as though it would destroy everything as it blanketed the area where Serafleur stood.

"Big Sister!" Asuna immediately grew anxious.

Serafleur gave a wry smile and silently allowed herself to be swallowed by the blast of magical power.

At that very moment, Sazex, the Demon Lord Lucifer of the Underworld, frowned and looked toward the Sitri territory.

"An unfamiliar Demon Lord class aura. Is it over at Serafleur's place? It seems something has happened..."

Muttering that to himself, Sazex headed toward the Sitri territory.

Serafleur: Magical Girls Are Invincible Under Heaven! ()

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

At that moment, Serafleur was pestering Nanoha and Fate, her face full of excitement.

Nanoha and Fate looked unaccustomed to Serafleur touching and feeling them all over. She even intended to study Raising Heart and Lightning Axe, frightening the two artificial intelligences into hiding directly inside Nanoha and Fate's clothes...

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

As her younger sister, she was the most qualified person to comment on just how clingy her older sister was.

Whenever Serafleur was about to return in the past, the thing Asuna dreaded most was always facing her.

Not only that, every time there was a parent-teacher meeting, Asuna also dreaded having her sister come to school.

Her parents were not interested in what happened to her at school. After all, they were Devils. How could they be like her, serving as the student council president at school and even being so responsible? Thus, the one who usually attended parent-teacher meetings was her sister.

Although her sister was responsible for diplomatic affairs concerning Devils, whenever it involved her younger sister, she would do her best to clear time from her schedule. It was Serafleur's way of loving her younger sister.

It was just that this love was far too heavy. Every time Serafleur came to school, Asuna felt like crying.

She was too clingy, so clingy that it felt as if the image Asuna maintained at school would be utterly destroyed.

"As expected of Magical Girls! Magical Girls are invincible under heaven! Hey, hey, hey... what exactly is going on with your transformations? Can you teach me? I'll do my best to help with anything you need, as long as you teach me how to become a Magical Girl! That is my only request, please..."

Nanoha and Fate had underestimated Serafleur's desire to become a Magical Girl. After exchanging a glance, they could not help smiling bitterly. She wanted to become a Magical Girl? They had no way to make that happen... They were not specialists in making Magi Devices...

Or should they let Serafleur study Raising Heart and Lightning Axe? Nanoha and Fate dismissed the idea the moment they thought of it.

Who knew what she might do to their Raising Heart and Lightning Axe... They did not even know her!

However, after seeing Serafleur like this, Nanoha and Fate felt that Chu Chen had been absolutely right...

She really was a Magical Girl fanatic... Nanoha and Fate felt helpless inside.

"Um... we do not have any other way either. We can transform only by relying on the power of our Magi Devices!"

Without her Magi Device, Nanoha could not transform either... After all, it was basically the equivalent of a transformation device...

"Oh, right, I see. That Magi Device is basically your transformation device. Then I really need a Magical Girl transformation device too... Do your people sell something like that? I can pay for it! Any price is fine!"

Human currency was not a problem for Serafleur at all...

If such a thing really could be bought in the human world, she absolutely would not refuse! No matter how much money it cost!

After seeing the troubled expressions on Nanoha and Fate's faces, Serafleur knew there was probably no hope, but—

"Or you can lend me your Magi Devices! I can find someone to study them!"

Serafleur intended to find Ajuka Beelzebub, the research fanatic of the Underworld, to study them.

In Serafleur's memories, Ajuka was the only person she knew who was best at research.

"About that..." Nanoha and Fate exchanged a glance, not knowing how to answer.

They were not so careless as to hand their Magi Devices over to someone they had only just met.

"Enough, Big Sister... Can't you see that your enthusiasm is making it difficult for them to adjust? No matter how strong they are, they still look like elementary school children..." Asuna immediately saw that the two were children still in elementary school.

Although Asuna had suffered a severe blow from elementary school students possessing this level of combat power, she could also tell from Serafleur's conversation with them that the two girls had not matured much mentally.

Thus, seeing Nanoha and Fate's overwhelmed expressions, Asuna silently sheltered them behind her.

That made Nanoha and Fate sigh in relief. They had finally escaped.

"Asuna-chan! How can you say that? Your big sister is welcoming our family's guests..."

Nanoha and Fate fell silent. Did this family always beat up their guests first and then study their weapons?

Yuuno and Arf also sighed in relief and silently followed beside Nanoha and Fate.

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

Originally, Asuna had thought they really were invaders or something. But after seeing what the two children were like now, she dismissed that answer. What could these two children possibly do? Although they were strong, with the Four Great Satans in the Underworld, these two could not stir up much trouble. Not to mention that the Sitri family even had Satan Leviathan.

Serafleur also looked curiously at Nanoha and Fate. She was very curious about the two of them as well.

"Um... actually, we are Magical Girls from a different world..."

Nanoha hesitated for a moment, then suddenly realized that she was undocumented in this world. If they investigated, they would seemingly be able to uncover her origins immediately, so she simply stated where they came from...

However, just as Nanoha finished saying those words, an extremely imposing voice suddenly rang out.

"People from a different world!"

Serafleur's eyes immediately lit up, and she hurriedly looked toward the source of the voice.

"Yo! Sazex-chan! Why did you come too?"

"The battle on your side was so loud. How could I not notice? If you are going to fight, can't you keep the noise down?"

Sazex was speechless, and Serafleur could not help laughing foolishly.

Rolling his eyes, Sazex did not intend to pay Serafleur any further attention. Instead, his gaze focused on Nanoha and Fate.

As a transcendent being, Sazex could naturally sense the immense magical power within Nanoha and Fate... Well, for humans, possessing such power at their age truly counted as extraordinary talent. They could even unleash Demon Lord class combat power.

At least, Sazex had never before seen humans of that age possess such combat power.

"You just said that you are people from a different world. Is that true?"

This was what Sazex cared about more now.

If people from a different world already possessed the ability to cross worlds, then Sazex's concern was only natural.

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

"Lord Demon Lord Lucifer, could you please stop making things difficult for my children here?"

Chu Chen: I Helped You Out, Yet You Want Me to Dress as a Girl! ()

"Sorry, Brother Chu Chen. We actually revealed our identities directly!"

Nanoha looked guiltily at Chu Chen before her, and an apologetic look also surfaced in Fate's eyes.

To them, their first mission had turned out like this, and they felt that they had messed it up.

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

"Don't worry. It does not matter whether you say it or not; there are no strict regulations about that here! Besides, I really did not account for the issue with the random teleportation. Who would have thought it would send you directly to a place like this?"

Chu Chen considered this an accident as well. No matter what, Nanoha and Fate being undocumented was beyond doubt.

Nanoha and Fate knew nothing about this world. If they fabricated lies about this, Sazex might become suspicious, so rather than invent a lie to conceal things from a Demon Lord Lucifer, 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 became suspicious, as a transcendent being, he would not make trouble for nine-year-old children. But house arrest and surveillance would definitely be unavoidable. He was a Demon Lord of the Underworld. No matter how amicable he normally appeared, someone who could become a Demon Lord could not lack ruthless methods. So Nanoha and Fate's choice had been the most appropriate one...

Besides, even if it had not been appropriate, Chu Chen could not possibly blame the two children.

"Is it really okay?" Fate looked at Chu Chen with considerable worry. She was afraid that they had ruined things.

Chu Chen only chuckled, then slowly walked over to stand before the red-haired Demon Lord, Sazex.

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

"People from a different world?" Although his tone was questioning, Sazex had already more or less confirmed Chu Chen's identity.

He could sense the astonishing magical power inside Chu Chen, enough to surprise even him.

If someone possessed such immense magical power, it was impossible for them to have no reputation in this world. Yet Sazex had never heard this name, nor had he heard descriptions of anyone with Chu Chen's appearance.

If Chu Chen was someone from a different world, then it was perfectly normal for him to have no reputation in this world.

In this world of DXD, there were also legends about Different Worlds, such as the neighboring EXE. Furthermore, someone named Lizevim was obsessed with invading Different Worlds, so Sazex knew about them.

He simply had never considered that a different world might launch an invasion or anything. The forces in their own world were already chaotic enough.

Now that people from a different world had truly appeared, Sazex immediately took the matter seriously.

He had to find out what their intentions were...

"Nanoha, Fate, and I are indeed people from a different world. Do not worry, Demon Lord Lucifer. I came to this world merely to experience the mysteries of a different world, not to play at invading or anything. Besides, have you ever seen an invader bring children along for fun?" As he spoke, Chu Chen's gaze casually swept toward Nanoha and Fate beside him.

Sazex glanced at Nanoha and Fate. At least his judgment in that regard was not wrong.

He did not sense any hostility from Chu Chen either. However, Chu Chen might also be intending to first test this world's combat power. In any case, they merely had to remain cautious for a while...

"Since that is the case, how long do you intend to remain in the Underworld? If necessary, I can arrange a guide or something."

One did not strike a smiling face. Sazex was not someone who attacked without a word, so he would observe first.

"I may stay in the Underworld for some time, and then I will head to the human world. During that time, I will have to trouble Leviathan to serve as our guide. Besides, Leviathan has fought my two younger sisters already, so they can be considered acquainted..." As he spoke, Chu Chen looked toward Serafleur, and at the same time—

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

"This card of mine is a random Magical Girl Transformation Card. It can randomly transform the user into any Magical Girl for battle, granting all of that person's abilities and strength during the transformation. I can offer this as payment."

"Really?!" Serafleur's eyes lit up, and without another word, she reached out to grab the Magical Girl card in Chu Chen's hand.

Unfortunately, Chu Chen quickly put the card away, and Serafleur could not help feeling disappointed.

"Then I'll leave them to you, Serafleur. Take them around the Underworld..."

"Sure, sure! Leave it all to me! Sazex-chan, go take care of your own business!"

Serafleur understood what Sazex meant. She had not let her hobby cloud her judgment.
