Use the power of the Demon King to destroy those reincarnated in another world

"I did not become a human being. Thanks to everyone, I became a human being from a fool." Nia slowly turned his eyes to Allen, "Once you said that I was weak. Yes, I am weak, pitiful, and helpless. The eye-catching presence remains today.”

Allen seemed surprised by what Nia said, with a dissatisfied expression on his face.

"But it's because of everyone that I'm here. It's because of everyone that I can stand, and because of everyone that I can keep moving forward. Because of everyone, I can be 'Nia Fultzbelt.'

There was no anger in his eyes.

However, Allen's eyes were full of anger: "This is just some beautiful nonsense." Allen said, glaring at the other party.

Nia responded with a smile: "You are such a fool. Isn't it the job of us 'scientists' to turn these beautiful nonsense and lies into reality?" Nia condensed the darkness in her palms and looked at Alan and Rai. La also drew the bow and prepared.

"Come on, let's do it. I'll show you my weakness." Nia said.

"Don't be kidding!" Allen shouted, and the darkness suddenly flew out from the feet of Nia and others, forming a sharp blade. Raila immediately jumped back with Nia.

"Why do you get frustrated every time things don't go according to my plan? Haven't you gotten over this habit yet?" Nia was deliberately provocative.

Allen slapped his tongue and disappeared into the darkness. Nia looked around calmly.

"First is preparation. We are not in a hurry." Nia said to Raila, gradually spreading the darkness in her palm to the dark area where Allen was.

Raila was still flying with Nia in her arms, staring into the darkness below. In an instant, many sharp arrows flew from the ceiling. Raila dodged dexterously while looking for Allen who had disappeared.

However, the scattered magic power makes the real body's location confusing and difficult to track.

"Raila, it's okay. Unless he uses transposition, the object will not disappear from there. Allen is not good at hiding, he just narrowed the room and created a hiding place by expanding the darkness." Niya was pulling Ila whispered in her ear.

"This is the evidence that the magic power of the spread darkness is balancing. Now, let's force him out first."

Raila nodded. Raila moved Nia behind her, and Nia turned around and wrapped her arms around Raila. Raila drew her bow and immediately started shooting.

"snapshot!"

The arrow that left the string suddenly exploded in the center of the room and scattered in all directions. Nya and Raila watched as the arrow was swallowed up into the darkness, but nothing changed.

Raila immediately turned and looked back.

"Strong bow!"

Arrows faster than sight penetrated the darkness behind. Immediately afterwards, Allen, who was shot in the abdomen by an arrow, emerged from the darkness and collapsed. Allen smiled slightly, grabbed the tail of the arrow and said, "It's not bad. After all, the arrow didn't even fly to our side."

Allen said confidently, Nia left Raila and flew towards Allen. Allen pulled out the arrow and looked up at Nia, who was about to fly down, with a smile.

At that moment, darkness suddenly appeared next to Nia, and several sharp swords struck Nia.

"Swap transposition!"

Nia and Allen's positions were reversed, and the sharp thorn pierced Allen.

"Besides, I also know very well that you will let your guard down and wait for opportunities." Allen looked down at Nia, but Lale was aiming at his forehead at zero distance.

"A strong bow with one arrow!"

The arrow penetrated Allen's head. However, Alan had a smile on his face. Nia suddenly felt panicked. When he turned around, the darkness behind him seemed to be spreading.

Then a hand suddenly reached out and grabbed Nia's neck. Raila squinted her eyes and watched this scene, watching Allen, who seemed to have been hit, recover, and that Allen had melted into the darkness.

Nia, who was grabbed by the neck, struggled, but the dark arm did not let go, and it turned into the form of Allen.

"Is that it?" Allen said to Nia, but Nia twisted her face into a smile, and the darkness began to seep in.

"Prankish little devil!"

Nia caused an explosion and black smoke spread everywhere.

"Bindfold your eyes."

Alan was startled and looked around. Then arrows flew from the smoke. Allen shook his head slightly to avoid the arrow that was about to approach his face, and then fired darkness from his right hand in the direction of the flight.

Raila, who was avoiding the darkness that struck him like lightning from the smoke, drew her bow tightly while flying.

"Powerful Arrow!"

The released arrow instantly becomes larger. It approached Allen at high speed, and even Allen looked embarrassed. The darkness was roiled by the impact, twisting the entire room in waves.

Allen felt uncomfortable while dodging arrow attacks. Now is not the time to launch a powerful attack with such a huge arrow.

Covering your field of vision is obviously not a wise choice. In fact, Raila, who had released the arrow, could no longer see Allen, and her eyes were moving around.

Allen narrowed his eyes as he considered her intentions, noting Nia's disappearance.

Obviously, this unwise choice was deliberately made by Nia.

Well, Nia is definitely onto something.

While he was thinking, the darkness on Allen's right side shook. His eyes turned in that direction, and Nia popped out from there.

Allen quickly fired a black arrow from his left hand, stabbing Nia.

“Night Tour!“

After Nia turned into darkness and disappeared, something entangled Allen's left leg and arm. If you look carefully, it's pure black darkness based on Nia's appearance.

The grinning creature made Eren narrow his eyes, and then Nia, who had multiple bodies on his right arm, right leg, left hand and back, grabbed Eren tightly.

Allen stared at them impatiently, protruding dark thorns all over his body to get rid of them, but his vision suddenly shook.

"what!"

Allen showed an anxious expression for the first time, a feeling he was familiar with.

"Was it injected with magic factor? When did it start?"

This is a technique he used against Raila in the Republic.

The trembling vision shook, the spreading darkness disappeared, and Allen reluctantly landed on the floor. But he was on his knees, his labored breathing showing pain.

Turning their eyes, Nia and Raila slowly landed on the floor, surrounded by countless shadows of darkness condensed into spheres.

"...That's right." Eren said with a wry smile, "Merge my darkness into your own. Everything else is a bluff. That's a funny way to go, Nia." He said as he revealed Satisfied expression.

However, Allen slowly stood up and said: "But..." He only suffered for a few seconds before he regained his calm expression and replied to Nia: "You are still too young."
