Taboo Manual for Raising a Succubus Girlfriend!

If the Demon King never existed from the beginning, what exactly is the power that separates the two worlds?

"I don't know how long this one-sided massacre will last. Perhaps... the demons will no longer exist. So, I have something to ask of you, Miss Ye Shi."

Maria shifted her gaze to the other side, looked into Zero's hazy eyes, and said in a trembling voice:

"I hope you can protect this child and use your identity as a magical girl to keep her alive as long as possible. She has only just gotten back on her feet. There are many beautiful things in this world that she has yet to witness."

"Maria..."

Zero's nose felt sore and tears welled up in his eyes. He walked forward and hugged the bruised Maria.

"Sorry, this is the only way."

Maria whispered an apology and gently stroked her head.

Zero, who was born from the void, is as important to her as family.

She was well aware of the strength of the Demon World, and knew that if things continued like this, they might be completely destroyed, so she wanted to entrust Zero to Yoshito. Even if the Demon World was completely destroyed in the future, the child would be able to live a happy and free life somewhere else.

This was the last thing Maria could do.

"..."

Ye Shi's expression was solemn, he wasn't sure if he had the ability to do it.

She is indeed a magical girl, but just an exiled magical girl who has lost her usefulness in the eyes of humans.

Whether she is still qualified to negotiate with humans and protect Yu Yi and Ling remains unknown.

But...

The development of the situation did not give her any time to hesitate.

“Boom—————”

A loud explosion sounded from above my head, something dangerous was about to appear.

There was an explosion, and huge rocks covering the sky and the sun fell from above, engulfing everyone in an instant.

...

"what happened..."

Half a minute later, a foot kicked away the smoothly cut boulder, and a black-haired werewolf woman appeared in the ruins.

It's Ye Shi.

She used a sharp blade to split the stone, turning the two-meter-diameter space around her into a safe zone without even a rubble.

"Are you guys okay?"

After Ye Si put away the knife, he turned around and asked about the situation of the two succubus girls behind him.

"Ahem... ahem... ahhh... ahhh... ahhh... ahhh... ahhh..."

Yu Yi was choked by the smoke and started coughing. Faced with this sudden situation, she covered her heart, which was about to jump out, with her little hands and was still in shock.

"I-I'm fine too."

Ling covered his chest and gasped for breath. He didn't know why, but he always felt a little weak and sweat covered his face.

"Why did it suddenly explode? What happened just now..."

Yu Yi turned her head to look around. There were gravels and dirt everywhere, and the dust had not yet completely dissipated, so she couldn't see the surrounding situation clearly.

However, when the floating dust slowly settled, a shocking scene appeared before our eyes.

“This, this is…”

Yu Yi's pupils contracted violently, revealing an expression of disbelief.

All the flames in the room have been extinguished. The only light source is the sunlight above the head, which penetrates from the surface into the ground and illuminates the foreign object that suddenly broke into this space.

That's... iron.

Giant iron.

After receiving a huge impact, the shape of the giant iron ship became distorted.

"Why, why did the falling iron appear here..."

Yu Yi looked up at the falling giant ship, her knees went weak, and she sat down on the floor, her body shaking uncontrollably.

"It came from above."

Ye Si's mind was very calm. Based on the deformation of the metal at the bottom of the hull, he analyzed that the ship must have fallen from the sky, then smashed through the ground and directly penetrated into this underground space.

If the falling point had shifted a little bit, it might have hit them directly on the head.

Is this... lucky?

"By the way, where's Maria?!"

Zero suddenly realized that Maria was missing.

She turned her head and looked around, trying to find Maria among the ruins, and was so anxious that she was about to cry.

"fine...."

A huge rock was lifted up, and Maria stood up from the ruins. Small pieces of gravel fell along the black feathers at her waist. She looked fine, except that her maid outfit was slightly stained.

"Very good..."

Zero slowly breathed a sigh of relief, but at this moment...

「Click」

The hatch on the falling iron made a sound.

It looked like someone was turning the rotary doorknob from inside, preparing to open it.

“....!”

Ye Shi and Maria realized that something was wrong and immediately took a fighting stance, becoming more alert.

The road they came from was buried in mud, and they couldn't go back the same way.

At this moment, this space was like the ancient Roman Colosseum, and they became beasts trapped in the venue with no way to escape.

“Crack, crack—”

The sound of orderly metallic footsteps rang out.

The densely packed mechanical soldiers were like a swarm of ants pouring out of a cave, instantly filling up most of the venue, standing in formation, with the guns in their hands reflecting a cold light.

"Humanity...humanity's army..."

Yu Yi looked at the emotionless mechanical soldier in front of her, her breathing trembling.

This is... a pure killing weapon.

"Be careful."

Ye Si gripped the hilt of the knife tightly in his hand, like a wild wolf on the snow, protecting Yu Yi and Ling behind him.

Facing such armed enemies, they could be dealt with one by one in street fighting, but in open terrain, facing large groups of troops and dozens of black gun muzzles, even Ye Shi did not have the confidence to easily eliminate these tough guys while protecting Yu Yi and Ling.

but...

If a battle breaks out, this is the only thing to do.

"clang"

The sunlight passed over the tip of the knife, and behind the dark edge, the sharp red eyes seemed to be able to cut off everything.

Ye Shi prepared to strike, and the atmosphere gradually became tense. Just when the two sides were about to fight...

“Beep—”

A mechanical electronic sound rang out.

Suddenly, the mechanical soldiers lowered their guns in unison, giving up their intention to fight.

"...?"

Ye Shi felt a little doubtful.

Swish swish swish...

The mechanical soldiers began to move again.

They marched neatly to the left and right, forming two lines, leaving a path in the middle.

"I didn't expect to see you here."

A hoarse mechanical voice sounded.

Among the dense black soldiers, a white alien slowly walked out.

It raised its right hand to signal the soldiers not to fire. Its face without a mouth or nose gave the inexplicable illusion that it was smiling, which was creepy.

"It's been almost a year since we last met..."

The white alien slowly stepped forward, its light green eyes looking towards this side, and it said a name in a nostalgic tone:

"Number 133."

The moment he heard this special number, Ye Shi's expression darkened, and dark memories emerged in his mind.

"Number 133, remember... Demons are evil."

This was Ye Shi's former name...

Perhaps, it would be more appropriate to call it a code name.

Not many people know this name. The "Artificial Magical Girl Project" was a secret experiment. After the project was terminated, the relevant personnel had been almost cleared out, and only a few high-level human beings still knew this secret.

But this robot in front of me, no...the person operating this robot is the one who started all this.

The guy who kept whispering in Ye Shi's mind, instilling distorted values, controlling her brain, ordering her to go to battlefields around the world, killing in the name of "justice", and finally exiling her to the demon world after squeezing out all her usefulness.

"I didn't expect you to be alive. Is there something wrong with the 'device'? It makes no sense..."

The white alien seemed particularly surprised that Ye Shi was still alive. He put his hand on his chin and observed Ye Shi carefully.

"Ok?"

Suddenly, it noticed the two demon girls behind Ye Si, and the light in its eyes dimmed slightly.

Could it be...

The white alien shook his head, quickly denying the thought in his mind. He turned to look at Maria, who was covered in bruises, with a smile in his eyes:

"Finally found you. You single-handedly wiped out more than ten of my troops. As expected, I can't let a potential danger like you get away."

"hateful...."

Maria covered the wounds on her body and gritted her teeth like a beast cornered.

"You, you are..."

Yu Yi noticed this strange robot, grabbed the hem of Ye Si's clothes with her little hands, and asked in a tone filled with fear and anger.

"I?"

The white alien blinked, thought for a moment, and then spread out his hands and said:

"To put it in a way that even a child can understand, I should be... a 'hero', right?"

"Brave.....one..."

Yu Yi was stunned, repeating the inexplicably familiar words.

"Yes."

The white creature raised its hands high. A ray of sunlight shone through the broken dome and focused on it. It looked like a descended god and shouted:

"I am a 'brave man,' but also a 'pioneer,' a 'hero,' an 'adventurer,' a 'scientist,' a 'leader,' a 'great man,' a 'pioneer of the times,' a 'God,' a 'divine,' and so on. You can call me whatever you like, but I prefer to be called... 'Justice.'"

Like a fanatic who has lost his mind, it keeps chanting its own title.

"Justice...are you worthy of being called justice..."

Maria clenched her fists, wishing she could destroy the robot immediately.
