DxD: Building a Demon Clan from Scratch

Fujimi Academy.

Lynn and his group walked leisurely toward the parking lot.

Whenever zombies appeared along the way, Saeko swiftly beheaded them before they could get within three meters of Lynn.

Rei and Saya followed behind like frightened quails, their necks shrunk as they cast wary glances at Saeko, then at Shizuka, before finally settling on Lynn.

It was obvious now, both Saeko and Shizuka were no longer ordinary humans.

Especially Saeko, who was terrifyingly strong.

And yet… both of them willingly followed that man's lead.

Just what was he?

No one would tell them.

Even now, they didn't even know his name.

And they didn't dare to ask.

Parking Lot.

"Ah! Found it!"

Shizuka waved at Lynn, standing next to a yellow-green school bus.

"Let's go."

The group boarded the bus.

The area was eerily quiet, as Saeko had already cleared out the zombies nearby.

"Uh…"

Shizuka sat in the driver's seat, fidgeting with the keys, momentarily confused.

Just then—

Footsteps sounded from outside.

"Quick! There's a bus here!"

The vehicle suddenly rocked as several people climbed aboard.

The first to step in was a man in a purple suit.

It was him.

Rei's expression darkened with disgust.

Then, she spotted Komuro Takashi behind him—and her eyes widened.

How could Takashi be with this scumbag?

So, he wasn't a good person either.

She recalled how Takashi had pestered her years ago, and thankfully, she had ignored him.

Her gaze turned cold as she shut her eyes in irritation.

She despised Shido Koichi.

But this school bus already had an owner.

Because of her connection with Saeko, she and Saya had been allowed to board this safe, reliable vehicle.

She wasn't about to jeopardize that by causing unnecessary trouble.

However, she did wonder…

Had Shido somehow evolved as well?

Shido glanced around and found only a handful of students on the bus.

The only authority figure was a female teacher.

Instantly, he felt emboldened.

"Ahem!"

Clearing his throat, he prepared to deliver one of his usual manipulative speeches to seize control of the bus.

But before he could.

"Saeko."

"Yes, Master!"

In an instant, Saeko vanished from her seat and reappeared in front of Shido.

His pupils shrank in shock.

Before he could react, a sharp pain struck his abdomen.

And he was sent flying off the bus.

Rei's eyes lit up with joy, and a weight lifted from her chest.

Good. Shido was still just an ordinary human.

Lynn remained indifferent.

He had already sensed Shido's group approaching.

Thanks to his earlier lightning strike, the butterfly effect had taken hold.

Far more zombies than in the original timeline had swarmed Fujimi Academy, yet this cockroach had still managed to survive.

As expected, scum like him always clung to life.

But then.

Lynn's gaze shifted to Komuro Takashi.

…Ah.

So that's how he made it.

He was leeching off the protagonist's luck.

"Hiss—"

Shido clutched his stomach, taking a sharp breath as he looked up at Saeko in disbelief.

Then, he straightened himself up and scowled.

"I am a teacher at Fujimi Academy! You dare attack a teacher?! This is outright defiance of authority!"

Takashi's expression hardened.

"Senpai, please apologize to Shido-sensei!"

He was furious.

Shido had gathered so many people under his leadership during this apocalypse, Takashi respected him for that.

As long as they followed Shido, he believed they would make it through this crisis!

If the people on this bus had simply handed over control, they too could have joined the group and survived together.

Instead, they had attacked Sensei Shido for no reason!

Takashi clenched his fists.

And to make things worse.

His first love, Rei, was sitting right there on this bus.

If this incident caused him to lose the chance to be with her, then…!

He wouldn't accept it!

But before he could act.

Saeko shot him a cold glance.

Then, she ignored him and turned back to Shido.

Standing over him, she unsheathed her blade.

Clang—

Shido froze.

A single bead of cold sweat dripped down his forehead.

"I didn't kill you on the bus because I didn't want your filthy blood staining it."

"Wait—"

His eyes widened in terror.

The next second.

A crimson line formed across his neck.

Bang!

His head hit the pavement, his lifeless eyes staring blankly ahead.

Silence.

The students who had followed Shido moments ago now stood in stunned confusion.

Takashi was frozen.

"Shido…Sensei…?"

Dead?

"You…!"

Overcome with rage, he lunged forward, reaching for Saeko's collar.

But before he could even touch her.

Slash.

His arm was severed.

It hit the ground with a wet slap.

"AHHHHH!!"

Blood sprayed everywhere as Takashi screamed.

Saeko's expression remained unchanged.

Saeko raised her blade once more.

Slash.

Takashi, dead.

Lynn tapped his chin in thought.

It seemed… something about the relationship between Rei and Takashi was different in this world.

Meanwhile, Saeko calmly wiped the blood from her sword before scanning the others.

"Anyone else want to step forward?"

No one answered.

Saeko sheathed her blade.

With that, she closed the bus door and took her seat.

The school bus started, leaving the academy behind.

No one dared to cause trouble again.

The lesson had been effective.

Saeko felt nothing about killing two humans.

No matter what someone's identity was, they needed to know their place.

That was one of her principles.

Now that she was her Master's sword, it was only natural to eliminate annoying pests for him.

Those people had bad intentions.

Saeko had merely shown mercy by only killing two.

On the Bus.

Rei stole a glance at Lynn.

Shido's death had completely relieved the weight in her chest.

She felt grateful to Saeko.

But she also understood…

Everything Saeko did was because of this man.

Her gaze lingered on Lynn's handsome face.

Her heart pounded faster.

A man worth relying on…

Saya sat beside her, barely daring to breathe.

All her past arrogance and pride were gone.

Meanwhile, Saeko patted her thighs and smiled sweetly at Lynn.

"Master, do you need a knee pillow?"

Her tone was gentle, completely different from before.

Lynn didn't hesitate—he lay down immediately.

His head sank into softness.

Saeko's eyes softened as she gently massaged his head.

Lynn, enjoying her service, pulled out his phone.

There was no signal between worlds, but thanks to [Demonic Summoning], he could still connect.

A cross-world chat system.

Unfortunately, he hadn't brought extra phones.

Next time, he'd prepare in advance so Saeko and the others could join the family group.

For now, he @mentioned Utaha.

Sigma Man: @Kasumigaoka Utaha, I won't be back tonight.

Kasumigaoka Utaha: ?
