DxD: Building a Demon Clan from Scratch

Fujimi Academy.

Busujima Saeko gripped her newly acquired katana and sliced cleanly through the head of a zombie.

"What has this world become?"

She flicked the blood off the katana and held it horizontally in front of her, the cold steel reflecting both her deep blue pupils and the approaching zombies surrounding her.

"Sensei, squat down."

"Eh?"

The blonde beauty with an explosive figure looked momentarily confused. But before her mind could catch up, her body reacted instinctively to Saeko's words.

Whoosh—

Saeko moved decisively, her katana tracing a deadly arc through the air.

Thud! Thud! Thud!

Three zombies collapsed instantly, unable to react.

"Wow! Saeko-san is amazing!"

Marikawa Shizuka, still crouched on the ground, clapped her hands excitedly, her eyes sparkling with admiration.

Saeko sighed helplessly and pressed a finger to her lips, signaling for silence.

Shizuka immediately covered her mouth with both hands, her large eyes blinking as she gazed up at Saeko.

"You can stand now, Sensei."

"Ah! Right!"

Shizuka nodded rapidly, picking up the medical kit she had taken from the school infirmary before following closely behind Saeko.

Saeko continued clearing the corridor of zombies, her thoughts running in the background.

These things weren't hard to deal with, but...

There were just too many of them.

She glanced through the window, her expression grim.

The dead swarmed toward the school in droves.

Judging by the sheer numbers, the first floor had likely already been overrun.

Saeko gripped her katana hilt tighter, her fingers turning white.

Even with her exceptional sword skills, she was still human.

She could get tired. She could get injured.

But the zombies?

They never stopped.

"This school isn't a place we can stay for long."

But…

"How do we escape?"

As she stared at the seemingly endless sea of zombies, for the first time, a deep sense of despair threatened to creep into her heart.

But—

Waiting for death wasn't the way of the Busujima family.

"Sensei, are you willing to move forward with the resolve to die?"

Saeko turned to Shizuka, seeking her opinion.

"Hmm..."

Shizuka placed a finger on her lower lip, deep in thought. Then, as if suddenly remembering something, her eyes brightened, and she reached into her skirt.

"Ah! Found it!"

She pulled out a piece of black parchment that radiated an ominous aura.

"Why don't we ask the Devil for help?"

Shizuka offered the parchment to Saeko like a child showing off a treasured find, her eyes full of expectation.

Saeko: "…"

For a brief moment, she regretted expecting anything serious from this airheaded nurse.

Yet, seeing the anticipation in Shizuka's gaze, she sighed and took the parchment.

[Devil Summoning Contract Document]

It certainly looked legitimate.

"Hehe."

"Saeko-san, don't underestimate this thing."

Shizuka lowered her voice conspiratorially. "This parchment appeared in the infirmary out of nowhere. No matter how many times I threw it away, it always returned to the same spot."

"Even fire couldn't burn it!"

"It's definitely a devil's prank!"

She nodded to herself as if fully convinced.

"Isn't it more likely to be some student's prank?"

Saeko wanted to say that, but before she could, a pen was already being shoved into her hand.

She silently glanced at Shizuka's bouncing figure and muttered under her breath, "Is that a dimensional storage pocket?"

Forget it.

She'd just humor her for now.

With that thought, Saeko took the pen and signed her name at the bottom of the parchment.

"Alright, let's play along—"

Before she could finish, the empty corridor was suddenly engulfed in dazzling light.

Buzz!

A pitch-black magic circle appeared beneath Saeko's feet.

Her pupils shrank, and she instinctively tightened her grip on her katana.

Step.

Footsteps echoed through the corridor.

"Are you my contractor?"

Saeko looked up, her expression blank.

A man with black hair, red eyes, and a noble bearing stood before her.

"...A real devil?"

She could hardly believe it.

But the magic circle beneath her feet was undeniable proof.

Tear—

Black wings tore through the fabric of the uniform he was wearing, unfurling majestically.

"The real deal."

Saeko's eyes widened in shock.

She opened her mouth but found herself momentarily speechless.

Smack!

Lynn's wing casually swatted away a sneaky hand reaching toward him.

"Owww! That hurt!"

Shizuka, who had been trying to touch his wings, crouched behind him, blowing on her hand to ease the sting.

Saeko's eyelid twitched. Taking a deep breath, she asked, "Sensei… what are you doing?"

"Hehehe."

Shizuka laughed sheepishly. "I just wanted to see if they were real."

Saeko: "…"

"Can't you show at least a little respect toward a devil?!"

"Be careful, he might just turn this world into a living hell!"

...

Wait.

The world was already a living hell.

As Saeko and Shizuka exchanged words, Lynn was deep in thought.

The moment he saw Saeko Busujima, he instantly recognized where he was.

One of the classic low-level worlds.

A well-worn setting.

But for him—and his Peerage—this world was perfect.

An ideal training ground.

Especially with how weak his Peerage members currently were.

Lately, Lynn had been thinking about how to help Utaha and Miko level up efficiently.

Modern society was too restrictive.

Cursed spirits were common, but they gathered in places with lots of people.

If he didn't want to draw attention, he could only hunt them at night.

But that was way too inefficient.

This summoning contract, however?

A perfect solution.

A world overrun by the undead was essentially a natural low-level grinding dungeon.

From now on, this would be his Peerage's training ground.

Besides…

This world also had potential Peerage members.

Lynn glanced at the ability displayed on his system panel—[Evil Pieces].

For some reason, he had a feeling it would be much easier to recruit new members here than in his own world.

With that in mind, Lynn turned to Saeko, a faint smile playing at his lips.

"So…"

He stared at her intently.

"Contractor, what's your request?"

Saeko took a deep breath.

She never expected that parchment to actually summon a devil.

Her entire worldview felt like it had been turned upside down.

After all, who would have thought devils really existed?

But…

Considering how the world had suddenly fallen into chaos, maybe the appearance of a devil wasn't that strange after all.

Either way—

He was already here.

She might as well ask.

Saeko's eyes flickered as she carefully chose her words.

"Then… devil."

"Can I ask you to…"

She exhaled slowly.

"...Save the world?"

(To be continued.)
