Taboo Manual for Raising a Succubus Girlfriend!

...

...

That's right..

My mission is to... kill the demon...

Since I'm going to die anyway, why not sacrifice everything for humanity till the end...?

The demons...are evil.

The demons...are evil.

what...

As long as you believe this, the noise in your brain will disappear and you will feel an unprecedented tranquility.

Yes, demons are evil.

What I just saw was nothing but a disguise of the demons.

I have not been abandoned by humans. This is the final mission they have given me.

Kill the Demon King...

In order for mankind to live a better life and never have to experience war again, I must fight to the end.

This is...

The final meaning of my life...

..

..

swish swish...

The garbage plastic bag made a noise.

"Why?"

The two demon students were attracted by the sound. After turning around, they saw blood-red eyes that made them shudder:

"Demon King..."

“Huh?! W-What?!”

"Where is the Demon King?"

"I, we don't know..."

The two demon students were terrified.

The Ye Shi in front of them was like a mad hungry wolf, with bloodshot eyes looking at them, making their bodies tremble uncontrollably and instinctively want to escape.

"Where can I find her..."

Ye Shi staggered forward, looking at the two of them through his wet black hair. A creepy atmosphere enveloped the entire alley.

"I, we really don't know... The Demon King often goes out to help people in trouble and rarely stays in one place..."

"People in need..."

“Right, that’s right!”

The two demon students nodded repeatedly, like little animals that were cornered, without even the courage to turn around and run away.

Seeing Ye Shi's silence, they thought they could finally escape, and just when they were about to breathe a sigh of relief...

"So, if we cause trouble, she'll show up?"

"Eh?"

Poof——

After a flash of cold light, blood gushed out.

The demon student didn't realize what was happening yet, he just felt his face getting hot and liquid sprayed on it.

The black-haired woman in front of him suddenly had a sharp blade in her hand, and blood was dripping from the cold tip of the blade.

Beside her, her close friend had collapsed on the ground, the blood gushing from her throat dyeing the alley red and splashing onto her face.

“Aa ...

The shrill screams broke the tranquility of the city.

"what happens!"

The patrolling police noticed the commotion in the alley. When they dropped their umbrellas and rushed inside, the two demon students had already fallen to the ground.

The black-haired woman held a sharp knife, her clothes were stained with blood, and the bright red blood mixed with the rain water, flowed past her feet and into the sewer.

As long as you create a commotion, the Demon King will appear.

So, what we need to do next is actually very simple...

That is..

Killing

..

"Ahhhhhhhhhhhhhhhh, someone's gone crazy, run!!"

Streets, shopping malls, schools, parks...

It's like a drop of red ink falling into clear water.

Ye Shi swung the blade in his hand, and blood began to spread. Corpses fell one after another, dyeing the streets red, like blooming red spider lilies.

She became an emotionless butcher.

During the killing, the brain felt an unprecedented pleasure.

That's the feeling...

This is... "justice".

..

..

"stop!!"

The childish shouts stopped the massacre.

Unlike the fleeing crowd, two petite succubus girls walked against the flow of the road and appeared in front of Ye Shi:

"That's too much... Who are you and why are you doing this?!"

Standing in front was a succubus girl with light pink hair. She looked at Ye Si, whose body was covered in blood, and shouted angrily without any retreat.

"Sister, be careful, I have a bad feeling..."

The succubus girl with snow-white hair was very cautious. She grabbed the former's clothes tightly, signaling her not to be impulsive.

"It's okay, let me teach her a lesson!"

However, the pink-haired girl was so angry that she couldn't calm down at all as she watched so many innocent civilians die. She clenched her fists so tightly that her teeth were almost broken.

"Where is the Demon King..."

Ye Shi shook off the blood on the tip of the knife, drew a moon on the ground, and asked in an emotionless tone.

"I am the Devil King!"

The pink-haired girl took a step forward and admitted it openly.

Perhaps because they had lived in a peaceful environment for too long, this seemingly young "Demon King" had no idea that humans could be so cruel and crazy.

A cold light flashes..

The moment she admitted her identity, Ye Si had already started to act. Without saying a word, he threw the blade in his hand and prepared to pierce her chest.

Blood spurts.

Just as expected, the snow-white blade pierced through the girl's thin chest, and the red tip of the sword appeared from behind her.

However, the person that Ye Shi pierced was another girl.

"Don't...hurt...my sister..."

The white-haired girl blocked the blade with her body, spitting out blood from her mouth, then fell to her knees on the ground, dying.

"what..."

The Demon King was stunned. Things happened so fast that she couldn't react.

She opened her eyes wide, her sister's blood dyed her face red, and the real smell of blood made her gradually realize something.

"W-why..."

When she touched her twin sister again, she was no longer able to respond and the light in her eyes was disappearing.

die...

This is....Death....

It's as easy as breaking a twig.

In just a moment, the only relative who had just been playing and frolicking with him died.

why...

Why do you do such a cruel thing...

The Demon King reached out and touched the crimson-stained sword, feeling the dark magic power and recalling the events of decades past.

(This is....Magical Girl....)

That was the first human-demon war.

No, that wasn't a war at all, it was just a one-sided invasion of the demons by humans.

At that time, this pink-haired girl was already the "Demon King".

Several magical girls with similar powers suddenly broke into the demon world and began to wreak havoc in the name of "justice", turning the entire demon world upside down.

It was an unwinnable war.

This weak "Demon King" could only kneel down and beg for mercy, using his own life as the price, begging the group of magical girls to spare his sister and the civilians of the demon world.

Originally, the demon king was ready to be killed, but he didn't expect that a girl shining with starlight just smiled, did nothing, and led the other magical girls and humans away.

Since then, humans and demons have been separated by unknown forces.

The war is over.

The demons were not completely slaughtered, but they still suffered heavy losses. Many demons lost their families and could only rebuild their cities in the ruins.

Originally, I thought peace could continue.

But now, the claws of mankind have once again extended to the demon world.

How many times must this be repeated before humanity is satisfied...

"Why do you do this? Why hurt us..."

The devil touched his loved one's wound and continuously injected magic power into her to heal her, but the blood still kept flowing out and could not be stopped.

"We just want peace, why do you humans always want to hurt us to be satisfied?!"

Feeling the death of her loved ones, tears as big as beans fell from her cherry-colored eyes, mixing with the scarlet blood.

but..

At that time, Ye Shi had been swallowed by the voice in his head.

She was completely unable to hear any sounds from the outside world, nor could she understand other people's emotions.

Dark magic power gathered in her palm, and a long sword appeared again, ready to assassinate the demon king.

"No matter how many times, I will stop you..."

The Demon King wiped the tears from his face, gently placed the body of his loved one back on the ground, and let the magic power condense into a staff in the palm of his hand, his cherry eyes showing determination.

The next moment...
