1046 -1033- The battle of brother and sister

"Bang!"

The sound of something shattering suddenly rang out, exposing Rozen and Avrora's figures in the air.

The magical conflict between them and Natsuki caused the "Invisibility jutsu" cast on Rozen and Avrora to be broken.

This commotion immediately caught the attention of the nearby armed forces.

"You...!?"

"Who are you...!?"

The fully armed members of the armed forces were all shocked in unison, and then without hesitation, they raised their firearms and aimed at Rozen and his group.

However, as they aimed, those guards saw the faces of everyone clearly, especially the expressionless face of Natsuki, which surprised them even more.

"I-Instructor Minamiya...?"

"That's Instructor Minamiya!"

"And that's Instructor Minamiya's brother...?"

"Why would these siblings...?"

The people looked at each other in astonishment.

The armed forces present naturally belonged to the Special Zone Security Force.

Within Itogami Island, the only administrators were the Artificial Island Management Cooperative formed by directors with various backgrounds. The ones tasked with maintaining order on the island were mostly part of the Special Zone Security Force.

As a Demon Sanctuary, Itogami Island was not allowed to have an army, but the Special Zone Security Force was equipped with state-of-the-art equipment to deal with demons, and their combat capabilities were not inferior to those of ordinary armies.

Now, since the Artificial Island Management Cooperative was preparing to block the Old Southeast Region, the armed forces mobilized naturally came from the Special Zone Security Force.

As instructors of the Special Zone Security Force, Natsuki's distinctive appearance couldn't be mistaken, leading to confusion among these armed forces affiliated with the Special Zone Security Force.

As for Rozen, the people of the Special Zone Security Force also knew him.

After all, because of Natsuki's indulgence, many members of the Special Zone Security Force had been assigned to be Rozen's drivers, picking him up and dropping him off at school every day. It would be strange if they didn't recognize Rozen.

Moreover, Rozen had often used Natsuki's permit to enter the island's library and database, reading various research, magical, and informational books. The guards stationed there were also from the Special Zone Security Force.

In such a situation, seeing Rozen and Natsuki suddenly appear, facing each other, these people couldn't help but feel confused.

However, these people obviously couldn't intervene.

"You all, step back."

Natsuki ordered coldly without looking back.

At her words, although the security forces felt puzzled, they still obeyed Natsuki's command and all stepped back.

Natsuki then spoke again.

"If you go back now, I can pretend nothing happened."

This was Natsuki's final warning.

"It seems you're determined to stop me, Natsuki-nee."

Rozen sighed softly.

As the saying goes, caring leads to chaos. In order to prevent Rozen from approaching danger, Natsuki was prepared to disregard everything.

However, this made Rozen feel a surge of anger.

"It's been like this since before. To protect me, you've always ignored my opinions, even disregarding everything, using any means necessary, blindly sacrificing."

Rozen said softly while his eyes suddenly turned cold.

"But it's time for you to stop treating me like a helpless child! You idiot sister!"

With Rozen's voice suddenly raised, the space in front of him suddenly fluctuated.

The space vibrated, and then a powerful shockwave erupted, crossing the distance in an instant and rushing towards Natsuki's direction.

However, almost at the same time, the space in front of Natsuki also violently fluctuated, emitting a shockwave that met Rozen's head-on.

"Boom!"

The shockwaves collided head-on, immediately erupting with a thunderous roar, like two invisible storms colliding and turning into violent winds, shaking in all directions.

"Ah—!"

Avrora exclaimed, but before she could react further, Rozen pulled her behind him, protecting her.

"What...!?"

"Be careful...!"

The members of the Special Zone Security Force who were watching the situation here were all shocked by the sudden onslaught of violent winds, either being blown away or knocked down by the force.

Rozen and Natsuki didn't hesitate at all, ready to fight.

Especially Natsuki, who seemed intent on forcibly dragging Rozen back from the beginning, showed no mercy in her actions.

"Save those words at least until you graduate from high school, idiot."

Natsuki remained expressionless as space in front of her turned into whirlpools, forming ripples like magic circles.

From within, countless chains emerged.

That was the magical tool forged by the gods, the nearly unbreakable "Lawbinding Shackles."

With this magical tool, Natsuki had apprehended countless magical criminals, including some pure-blood vampires.

Now, Natsuki was ready to use them to apprehend her own brother.

Once entangled, magic would be sealed.

At that moment, Rozen could only be obediently dragged back.

Unfortunately...

"In terms of knowledge and learning, I can already rival doctoral and professorial levels. Even a teacher like you can't teach me anything now, let alone waiting for high school graduation, idiot."

Rozen extended his hand, and the space in front of him also rippled, allowing numerous chains to burst forth.

Facing the magical tools forged by the gods, Rozen also wielded his own replicated weapon, the "Injunction Shackles," engraved with runes of wisdom and divine power, whose strength was absolutely not inferior to the "Lawbinding Shackles," and even seemed to surpass them.

Natsuki seemed to understand this.

"If you're not an idiot, you should know clearly for yourself how foolish it is to willingly venture into danger."

Natsuki waved her hand, and the countless "Lawbinding Shackles" shot out, gracefully evading the incoming "Injunction Shackles" like spiderwebs, scattering in all directions, then converging from all directions like spears, surging towards Rozen, surrounding him.

"So you're willing to do anything to keep your brother away from danger? Then why teach me magic? Why teach me strength? If you want to cultivate hothouse flowers, go find some elsewhere! I don't need it!"

Rozen's magic surged, turning into a continuous stream of psychic energy covering the "Injunction Shackles," transforming the countless chains into living dragons that moved abruptly and unexpectedly, turning and plunging into the numerous ripples of space that appeared just as abruptly.

These ripples of space appeared around Rozen, allowing white chains to burst forth, precisely intercepting the incoming "Lawbinding Shackles."

"Clang! Clang! Clang! Clang! Clang!"

The next moment, chains collided continuously, bouncing off each other, causing countless sparks to flicker, blindingly bright.

"Too naive!"

Natsuki immediately waved her hand again, and the repelled "Lawbinding Shackles" all twisted in midair, flying towards Rozen once more.

"Who's the naive one?"

Rozen smirked, his psychic energy moving, and the "Injunction Shackles" around him, more agile than Natsuki's, intercepted them.

The siblings engaged in a dazzling and extremely intense attack and defense amid their bickering.
