Chapter 21

"Ara ara, unexpectedly pure."

Himejima Akeno, who witnessed the whole process, narrowed her eyes with a motherly smile.

Kasumigaoka Utaha's body stiffened slightly.

Just now, her mind was full of Lin En, and she had completely forgotten the existence of others.

Damn it!

Wouldn't she have been watched by everyone the whole time?

This is social death!!

Kasumigaoka Utaha felt a bit frantic inside, but she still had to force a calm appearance on her face.

She took a deep breath and suppressed all her emotions.

However

Her heart was still beating so fast.

She glanced at Lin En quickly and muttered, "My first kiss, I guess it was cheap for him."

"How is it?" Rias asked with concern, "How is Kasumigaoka-san recovering?"

"Should be, okay?"

Kasumigaoka Utaha smiled awkwardly.

Rias looked back and forth, then smiled, "It seems Mr. Lin En's magic replenishment effect is quite good."

Kasumigaoka Utaha's face stiffened.

She really had to bring up the sore spot.

Rias looked at Kasumigaoka Utaha with emotion.

"I didn't expect Kasumigaoka-san's ability to be able to master even Ultra-Class magic so quickly. It's truly an incredible ability."

Just with this one ability, Kasumigaoka Utaha's potential was extremely high.

Once she grew up, her strength would definitely be no less than Akeno's.

Such a subordinate made even her envious.

After Rias said this, Kasumigaoka Utaha remembered what she had done before.

Only then did she turn around to look at the pit caused by the lightning strike.

Kasumigaoka Utaha pondered, "Although the power is not bad, I always feel it's still lacking a lot."

This was also the reason why she had staked all her magic power just now.

"Of course."

As a lightning expert, Himejima Akeno explained:

"The full release of the power of Lightning Strike can affect the weather. With Kasumigaoka-san's current magic power, it's not enough to support the maximum output of Lightning Strike."

"I see..."

Kasumigaoka Utaha nodded in realization.

Indeed.

As an Ultra-Class magic, although the completion was very high, Utaha had not exerted its full power at all.

However...

This was enough.

Lin En raised his index finger, and black lightning snakes danced on his fingertip.

The moment Kasumigaoka Utaha's Grimoire recorded the Lightning Strike magic, Lin En had also silently completed his mastery of the Lightning Strike magic.

As a High-Class Devil, he could perform many operations with Lightning Strike magic in his hands.

For example, this silent lightning.

No sound, no magic power fluctuations.

Everything was firmly locked within this tiny black lightning.

Only when it hit the enemy would it release everything.

Therefore, no one present could perceive Lin En's actions.

Except...

Himejima Akeno, who was abnormally sensitive to lightning elements.

Himejima Akeno opened her eyes and stared tightly at the black lightning on Lin En's index finger, horror flashing in her heart.

That black lightning, it seemed like Rias's magic power.

Is it lightning containing the aura of destruction...

Lin En smiled at her slightly, closed his palm gently, and dissipated the lightning.

Seeing this, Himejima Akeno also smiled and withdrew her gaze.

However, her heart could not calm down no matter what.

Although it was black lightning.

But without a doubt, it was the Lightning Strike spell.

Black, it was not strange either.

Although she didn't want to mention it.

But that bloodline that disgusted her also made her lightning unusual.

What she found strange was, Lin En, he only looked at the Lightning Strike scroll twice, right?

Why did he look so proficient?

The control over Lightning Strike just now, even she couldn't do it.

Lin En Vapula.

This only bloodline of the Vapula family doesn't seem simple at all.

On the other side.

Rias was still sighing, saying with regret, "It's a pity, even with Ultra-Class magic, I couldn't test the upper limit of Kasumigaoka-san's ability."

Lin En smiled and said, "It's okay, if Miss Rias wants to test it, you can contact me anytime."

Rias rolled her eyes at him and said irritably, "Forget it, this time an Ultra-Class magic was lost, who knows what will be lost next time."

"Tsk, what a pity."

Lin En looked regretful.

With the foundation of the Gremory family, Lin En didn't think one Ultra-Class magic was everything.

Not to mention Rias had a Demon King brother with Transcendental strength; he could definitely farm a lot of gold coins.

Having squeezed Rias almost dry, Lin En prepared to leave.

Before leaving, Rias arranged for Toujou Koneko to take them around Kuoh Town.

"So, why is it an arcade?"

Kasumigaoka Utaha looked at Lin En and Toujou Koneko speechlessly.

"K. O.!"

"Lost again."

Toujou Koneko watched the character she was controlling fall to the ground, her expression slightly stunned.

"Senpai, so strong."

Although Toujou Koneko's tone had no ups and downs, Lin En could hear her seriousness.

"I say, we've played enough, right? If we don't hurry, we won't catch the bus back."

Kasumigaoka Utaha looked at the time, her right leg shaking constantly.

For some reason, seeing Lin En and Toujou Koneko playing so happily, she felt a bit irritable.

"That's true."

Hearing Kasumigaoka Utaha's urging, Lin En gave up the idea of starting another round with Toujou Koneko.

Although he had learned 'Magic Circle Jump', he hadn't placed coordinates at home yet, so he could only continue to take the bus back.

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

"Senpai."

Toujou Koneko pulled Lin En's clothes and then took out a flyer, "Please accept this."

Lin En took it and glanced at it.

Devil Summoning Contract.
