Reborn as Issei Hyoudou: The Phat to Supremacy

The night was quiet.

Too quiet.

I stood alone in the forest behind Kuoh Academy, my eyes closed, my breathing steady. The faint hum of power coursed through my veins, a strange mixture of Hakai's destructive aura and my newly acquired Arcane Energy Mastery.

I raised my hand, letting my senses expand.

For the first time, I could see it.

The flows of energy around me—mystical currents twisting through the air, weaving through the earth, pulsing beneath my skin.

This…

This was Arcane Perception.

With this, I could understand magic on a fundamental level. The mechanics behind it, the structure, the movement. It was beautiful—yet terrifying at the same time.

Because now, I knew.

I knew that if I combined Hakai with this level of precision…

I could create something far worse than destruction.

I smirked.

But that was for later.

Right now, I had a mission.

I pulled up the Chat Group interface.

[Multiversal Chat Group]

[Supreme Sorcerer]: Have you tested the arcane flow yet?

[Perverted Dragon Emperor]: Yeah. It's insane. I can literally see the structure of magic now.

[Tactician from Another World]: Then you should be able to refine your techniques more efficiently. Magic isn't just about power—it's about control.

[Demon Lord in Disguise]: Heh. Control is nice and all, but I want to see how he uses it in battle.

[God of Thunder]: Agreed! What use is power if not tested in combat?

[The Caped Baldy]: Just find someone strong and punch them. Simple.

I chuckled.

Don't worry. I won't have to look for a fight.

It's coming to me.

And sooner than I thought.

[Kuoh Town - Church District]

The abandoned church loomed in the distance.

The place reeked of fallen angel energy.

I wasn't alone.

Rias had sent me, Kiba, and Koneko to investigate reports of strange activity near the outskirts of Kuoh.

A cover mission.

But I knew what this really was.

This was the start of the Asia Arc.

I exhaled. In the original timeline, this was where Issei first clashed with the Fallen Angels, where he met Asia Argento, the exiled nun.

But this time?

This time, things would be different.

Because I wasn't the same Issei anymore.

Kiba crouched behind some rubble, his hand on the hilt of his sword. "I can sense them inside," he muttered. "At least four signatures."

Koneko, standing beside me, frowned. "They're waiting."

I smirked. "Good. Saves us the trouble of finding them."

Kiba raised an eyebrow. "You seem confident."

I rolled my shoulders. "Just a feeling."

A very good feeling.

Because tonight, I was going to show them that Issei Hyoudou wasn't just another weakling.

He was a threat.

[Inside the Church]

We stepped into the dimly lit interior. The scent of blood and old wood filled the air.

At the center of the room, a single figure stood waiting.

A girl with blonde hair, clad in a nun's habit.

Asia Argento.

She looked at us with wide, innocent eyes. "P-Please… help me," she whispered.

And then—

A voice echoed from the shadows.

"Well, well… looks like our little guest brought company."

I turned toward the sound—

And saw Raynare.

Dressed in her black trench coat, her violet eyes gleaming with amusement.

Behind her, three more Fallen Angels stood.

Dohnaseek, Kalawarner, and Mittelt.

Four-on-three.

But honestly?

It wasn't nearly enough.

Raynare smiled. "So, you devils actually came. I was wondering how long it would take before you stuck your noses into our business."

I stepped forward, cracking my knuckles. "Yeah, well… you guys aren't exactly subtle."

She chuckled. "And you… I remember you."

Her eyes darkened. "You should be dead."

I smirked. "Yeah, well… I got better."

Raynare's lips curled into a sneer. "You have no idea what you're getting yourself into, boy."

I shrugged. "Maybe. But I do know one thing."

I clenched my fist—Hakai flared around my hand.

"You're not leaving here alive."

Raynare's eyes widened.

She felt it.

The raw, primal force radiating from me.

Dohnaseek tensed. "That energy… what the hell is he?"

Kalawarner frowned. "That's not normal devil magic."

Mittelt took a step back, gripping her light spear. "That's… dangerous."

Raynare's expression twisted.

She didn't understand it.

But she knew it was a threat.

She knew she had underestimated me.

And she had just realized—

It was already too late.

[Multiversal Chat Group]

[Demon Lord in Disguise]: Oh? The battle's starting?

[Supreme Sorcerer]: Let's see what he does.

[God of Thunder]: Show them the might of destruction!

[The Caped Baldy]: Just end it quickly.

I smirked.

Yeah.

I think I will.

I stepped forward, my aura crackling with power.

"Let's get started."

And then—

I attacked.
