I Was Reincarnated with OP Invincibility, so I’ll Beat ’em Up My Way as an Action-Adventurer

117. Do You Want To Fight?

The morning sunlight streaming through the window is blinding.

Beside him lay Hannah, peacefully sleeping, her breath steady.

She was in her mid-twenties and worked as a clerk at the transport company where Jack was employed.

Their relationship had recently progressed to the point where colleagues referred to them as lovers.

“Mm…”

With a faint sigh, Hannah stirred.

“Ah, were you watching me sleep again?”

Her shy, bashful smile filled Jack with affection.

In his forty-three years of life, he had never felt this way before.

“Sorry, I just…”

Feeling embarrassed, Jack struggled to find the right words.

“From now on… um, I hope we can…”

“What’s this all of a sudden? You’re acting so formal.”

Hannah chuckled softly.

Bathed in the sunlight from the window, her smile looked more beautiful than ever.

Her somewhat droopy eyes and plain features might seem average to others.

But to Jack, she was the most beautiful woman in the world.

“The pleasure’s all mine,” she said warmly, drawing closer to Jack.

Their lips met lightly.

He wished this moment could last forever.

Peaceful and calm.

Happy and warm.

──It had already been more than a week since his battle with Levin.

On his way to face Levin, Jack had cut down numerous soldiers.

He even defeated four S-rank adventurers, causing quite a stir.

Because Jack fled immediately afterward, no one had yet realized it was his doing.

For now──.

The weight of having killed Levin and Miranda still bore heavily on his heart.

Considering their atrocities—controlling and dominating the wills of many—perhaps they got what they deserved.

Even so, the fact remained: Jack had taken lives.

The lingering unease wouldn’t leave him.

That’s why Hannah’s warmth brought such solace to his troubled soul.

──It was then.

A shiver.

“…!?”

An eerie sensation surged through his entire body.

“What… is this…!?”

He sensed a malevolent presence somewhere nearby.

Only Jack, with his [Enhancement] ability, could detect this faint—very faint—disturbance.

Something was there.

Far away.

Something ominous.

Something that couldn’t be ignored.

──Thump.

His heartbeat suddenly escalated.

It was a strange feeling.

Like a surge of battle lust, an inferno ignited within his chest, threatening to burst.

“…I have to go.”

He muttered unconsciously.

Getting out of bed, he began dressing.

“Jack…?”

Hannah looked at him quizzically.

“…Sorry. Something came up, and I have to go.”

Lowering his gaze awkwardly, Jack felt a pang of guilt.

This was the first morning they had woken up together.

But even knowing that, an overwhelming urge pushed him to leave.

He didn’t understand why.

But still──.

Jack sprinted through the capital, his legs enhanced by his ability.

The ominous presence came from the wilderness on the city’s outskirts.

Leaving the capital behind, he stopped after running some distance.

“…Here?”

Nothing lay before him.

Yet, something was there.

He was certain of it now.

The strange compulsion to come here had led him to face whatever lay ahead.

“Fiorega, is it?”

Suddenly, a voice echoed in his mind.

It was a majestic male voice—the war god who had granted Jack his power: Vim Forse.

“What’s that?”

“It’s a technique devised by the winged goddess Ga-Zegalia-Fio, used to manipulate alternate spaces.

The demons likely adapted it to create a special domain,” Vim Forse explained.

“So, this presence… it’s a demon?”

Jack clenched his teeth.

A fierce battle spirit welled up within him, setting his body ablaze with anticipation.

“They’re inside, aren’t they?”

“What’s this? Do you want to fight them?”

The war god sounded surprised.

“If I leave it alone, people might get hurt.”

Hannah could be in danger too.

Muttering inwardly, Jack took a deep breath.

He imagined enhancing his entire body—

His skin is like steel.

His limbs filled with power.

Grace is like a beast.

Strength like a beast.

The fighting spirit of a beast.

As he focused, his body began to transform.

A knight wearing a wolf mask.

A dark beast knight.

“So, you’ve entered Code Beast mode. Hah, you’ve grown quite eager to fight.”

Vim Forse chuckled.

“Is this the influence of that boy from the other day? In time, you’ll reach even higher levels…”

Jack didn’t understand the war god’s muttered words.

But his hostility toward the demon in the domain burned fiercely.

He would protect what mattered most to him.

Anything that threatened that would be eliminated.

“──Shatter!”

With a burning spirit, Jack slammed his fist into the empty space before him.

Unleashing his full strength, his punch resounded like clashing metal.

Cracks spread through the air.

Then, with a sound like shattering glass, the scene before him rippled and broke apart.

Jack stepped through the fractured space.

“What is this…?”

The wilderness was gone, replaced by plains shrouded in a pale blue mist.

Ahead stood a giant over twenty metils tall, accompanied by a boy dressed in black.

Floating in the air was a girl clad in a gothic-lolita dress with wings.

And opposing them were three familiar figures.

Jack recognized the boy and the girls—they were the ones who fought the Demon General Dialva during the assault on the capital.

“We meet again… Haruto.”
