DxD: Building a Demon Clan from Scratch

The so-called magic replenishment is a method of restoring magical power through the exchange of bodily fluids.

Among devils, magic replenishment is considered a reward from a master to their followers.

Utaha felt Lynn's tongue roaming around her mouth like its owner.

"Why are you... ngh~ sticking out your tongue like that...?"

Utaha's eyelashes trembled slightly. Her cheeks were flushed, and she pursed her lips. Her crimson eyes seemed to be focused on Lynn, yet at the same time, they drifted past him, as if staring at the scenery behind him.

"To maximize the effects of magic replenishment."

Lynn responded righteously.

He was seriously committed to replenishing magic.

It was just that Utaha had consumed too much magic power, so the replenishment process had to be… a little more intense.

"Oh my, how pure."

Akeno, who had witnessed everything, narrowed her eyes and smiled with an amused expression.

Utaha's body stiffened slightly.

Just now, she had been completely focused on Lynn and had momentarily forgotten the presence of others.

It's over.

Had she been surrounded by people this whole time?

This was social death!

Utaha nearly exploded with embarrassment internally, but outwardly, she forced herself to remain composed.

She took a deep breath, suppressing all her emotions.

But…

Her heart was still pounding rapidly.

She stole a quick glance at Lynn and murmured, "My first kiss… I let him take it for free."

"How is she?" Rias asked with concern. "Has Kasumigaoka-san recovered?"

Utaha smiled awkwardly.

Rias studied her expression, then smiled knowingly. "It seems that Mr. Lynn's magic replenishment is quite effective."

Utaha froze on the spot.

W-What kind of joke is this?!

Rias, however, was looking at her with admiration.

"I didn't expect Kasumigaoka-san to grasp even super-tier magic so quickly. That's quite the remarkable talent."

With such an ability alone, Utaha had immense potential.

Once she fully developed, her strength wouldn't be inferior to Akeno's.

Rias was honestly envious of having such a capable peerage member.

After hearing this, Utaha was reminded of what she had just done.

She turned to look at the crater left by her previous lightning spell.

Utaha contemplated, "The power was decent… but I still feel like it wasn't enough."

That was why she had gambled all her magic power on that one attack.

"Of course."

As an expert in lightning-based magic, Akeno explained,

"The full power of a Lightning Strike can affect celestial phenomena. With Kasumigaoka-san's current magic reserves, she wouldn't be able to sustain its maximum output."

"I see…"

Utaha nodded in understanding.

Indeed.

Even though she had managed to execute a super-tier spell, she hadn't fully unleashed its potential.

However…

This was already a big step forward.

Lynn raised a finger, and a flicker of black lightning danced at his fingertip.

The moment Utaha's Devil Tome recorded the lightning spell, Lynn had simultaneously grasped full control over it.

As a High-Class Devil, lightning magic in his hands could be manipulated in countless ways.

For example, this Silent Thunder.

No sound, no visible magical fluctuations.

All of its power was tightly compressed into a single strand of black lightning.

Only upon impact would it unleash its devastating force.

Thus, no one present noticed what Lynn had just done.

Except…

Akeno, whose sensitivity to lightning was exceptionally high.

She widened her eyes, staring at the black lightning on Lynn's fingertip with shock.

That energy… it felt eerily similar to Rias's Power of Destruction.

Lynn simply smiled at her, then lightly clenched his palm, dispersing the lightning.

Seeing this, Akeno smiled as well and looked away.

But internally, she was anything but calm.

Even though it was black lightning…

There was no mistaking it—it was lightning magic.

Its color wasn't the strange part.

Although she didn't like to dwell on it, her own bloodline had also tainted her lightning with an unusual hue.

What was strange, however, was how quickly Lynn had mastered the spell.

Hadn't he only glanced at the scroll for Lightning Strike twice?

Yet the level of control he had just displayed…

Even she couldn't achieve that.

Lynn Valefor.

The sole surviving member of the Valefor bloodline…

He was definitely not simple.

On the other side.

Rias sighed regretfully. "It's a pity. Even with super-tier magic, we still couldn't gauge the upper limits of Kasumigaoka-san's abilities."

Lynn smiled. "It's fine. If you ever want to test again, Rias, feel free to call me anytime."

Rias rolled her eyes at him. "Forget it. This time, we only put in one super-tier spell. Who knows what kind of magic we'll end up using next time."

"Tsk, what a waste."

Lynn clicked his tongue in disappointment.

With the Gremory family's deep foundation, he doubted that a single super-tier spell was all they had to offer.

Besides, Rias had a Maou-level older brother. Surely, there were plenty of powerful techniques waiting to be borrowed.

After practically squeezing every benefit he could out of Rias, Lynn prepared to leave.

Before that, Rias arranged for Koneko to take them on a tour around Kuoh Town.

—Later, at the Arcade—

"…So, why did we end up at an arcade?"

Utaha looked at Lynn and Koneko in silent disbelief.

K.O.!

"…I lost again."

Koneko stared at her defeated character on the screen, her expression slightly stunned.

"Senpai, you're strong."

Though her tone was flat, Lynn could tell she was serious.

"Are you two done playing yet? If we don't hurry, we will miss the last bus back."

Utaha glanced at the time, her right leg tapping impatiently.

For some reason, watching Lynn and Koneko enjoy themselves irritated her a little.

"You're right."

At Utaha's urging, Lynn gave up on playing another round.

Since he had yet to place a teleportation marker at his home, he still had to rely on the bus to get back.

"See you next time, when you're free, Koneko."

"Senpai."

Koneko tugged on Lynn's sleeve and handed him a piece of paper. "Please accept this."

Lynn glanced at it.

A Devil Summoning Contract.

Specifically, one exclusive to Koneko.

"Senpai, I want to learn how to fight."

Koneko looked up at him, her golden eyes full of determination.

Lynn glanced at the nearby Street Fighter arcade machine.

Got it.

This was the kind of fighting she meant.

"No problem. If you have time, I'll invite you over to my place."

After parting ways with Koneko, Utaha crossed her arms and followed beside Lynn.

"You're calling her by her name."

Lynn looked at her oddly. "Why do I feel like you're a little jealous?"

"Hah? As if I—"

Utaha was about to deny it when her brain suddenly stalled.

Wait.

She was jealous.

Utaha looked at Lynn, her gaze unconsciously drawn to his thin lips.

Damn it.

She might be falling for him.

But… they had only known each other for two days?!

Memories of the past two days flashed through her mind, stopping at the moment of magic replenishment.

Her heart pounded.

"Why are you just standing there?"

Lynn stopped, waiting for her to catch up.

Utaha collected herself, brushed back her wind-blown hair, and walked forward, linking her arm with his.

"I admit… I'm a little jealous."

Lynn blinked, then grinned. "Well, you should control yourself. I'm a devil planning to build a harem."

"…You really are a shameless devil."
