High School DxD: Return of the Crimson Dragon Emperor

Chapter 333: Chapter 323 The Sniper, Returns

『——The Oppaiser!』

Sensei’s voice, announcing that name, played on repeat in my head.

Oppaiser...

I see. So it’s called the Oppaiser.

Oppaiser...

Oppaiser... Oppai... ser...

Oppai... Oppai...?

The word ”Oppai” replayed over and over again.

And then——.

”DIDN’T YOU HAVE A SLIGHTLY COOLER NAME THAN THAAAAAAAT?!”

I roared, looking up at the heavens!

That was its name?!

I’ve seen the machine a few times, but this is the first time I’m hearing what it’s called!

Why, of all things, ”Oppaiser”?!

You could have thought of anything else!

Sure, I love boobs!

I am the Oppai Dragon!

But that naming sense is terrible!

『”Terrible”? That’s rude. I was one of the ones who named it, you know?』

It was you, you Useless Goddess!

What kind of name did you give it?!

『But Issei is the Oppai Dragon! Azazel-kun and I thought really hard about it!』

That’s just taking it literally!

Your hard work went in the completely wrong direction!

Azazel-sensei’s voice came through the communication magic circle at my ear.

『To be honest, I wanted to make it smaller, but that size was the limit. The ”Nyuu-power”—the Milk Power—was just too immense. It went beyond the framework of the technology I possess.』

『Which just goes to show that the power of boobs is magnificent. But, Azazel-kun. This decides our new merchandise line, doesn’t it?』

『Right you are. This will sell. Let’s deliver this not just to the Underworld, but to every mythology’s Oppai Dragon fans!』

『Yes!』

Wait, the unmarried former Governor General and the Useless Goddess are planning a new product line?!

Your commercial spirit is way too strong!

And if you’re commercializing it, you’re definitely planning to put it in the Tokusatsu show too, aren’t you?!

Ignis spoke up.

『Come on, time to dock, Issei! Show him your true power!』

『That’s right. That’s why we adjusted it at a sprint. Go blow him away, Issei!』

The two of them urged me on.

We’ve come this far; I’ll leave the name of the machine aside for now.

Do whatever you want with the merchandising.

——Right now, what I want is the power to punch the enemy in front of me.

Asem, now in his young adult form, smiled.

”Aha♪ Now that we’ve reached this point, something interesting has appeared. ——I’ll wait until your preparations are complete. Come on, show me your full power. What I want to know, what I desire, is everything the current you possesses.”

Waiting until I’m ready, huh?

What a generous God providing such service.

But, I’m grateful he’s not attacking.

And if that’s what he wants, I have to put on a show.

——I’ll give him everything I’ve got.

I glanced at Asem once, then flew high into the sky.

I climbed rapidly, piercing through the clouds of the Netherworld.

The red machine sent by Azazel-sensei danced into the sky, following me.

When the red machine positioned itself behind me, I shouted!

”——Docking!”

The armor on my back slid open with a mechanical clack-clack.

A jewel appeared on my back.

A voice resonated from the jewels on my armor and the jewels embedded in the machine.

『Docking Sensor!』

『Oppaiser Docking Mode! Oppaiser Docking Mode!』

The machine transformed, revealing connection ports.

Those ports were also embedded with jewels, which connected to the jewel on my back with beams of light.

As the Oppaiser connected to my back and became one with me, the EXA armor began to shift into a more optimized form.

The boosters on various parts were miniaturized, and the cannons stored in the gauntlets disappeared.

In exchange, the wings on my back grew a size larger.

The EXA armor, which had been a forced amalgamation of the Solid Impact, Welsh Blaster, and Sonic Boost armors, had always felt slightly misaligned in its power distribution.

I could feel that being corrected now.

——The gears of Nyuu-power had meshed perfectly.

A dazzling radiance erupted from the jewels all over my body, illuminating the Netherworld!

On each and every jewel, the character for ’∞’ floated up.

Is this... representing infinite power?

Ignis answered my question.

『No, that doesn’t mean infinity. It represents boobs.』

It’s boobs?!

Finally, boobs have appeared on the jewels!

I mean, sure, it doesn’t not look like them... wait, if I look closely, there are dots inside the circles!

Two circles, with a dot in the center of each!

These are boobs!

『In this moment, the Nyuu-power from Alice-chan and Rias-chan that was inside you, Issei, has fit together perfectly. The powers of the Double Switch Princesses have meshed within you. This form, capable of utilizing full Nyuu-power, is——the Double Oppaiser, I suppose.』

Why did you stretch the sound?!

Why did you elongate the ”O”?!

Would ”Double Oppaiser” not have been enough?!

『Just felt like it!』

Every single time, this Useless Goddess is just winging it!

**~ Meanwhile, with the Double Switch Princesses ~**

Around the time Issei completed his docking with the Oppaiser, a change occurred in Alice and Rias as well.

The change was obvious to anyone watching; Vika, who was clashing with Alice, and those surrounding Rias could all perceive it.

That change was——.

””What is... this...?! My nipples are... glowing?!””

In the field mimicking Kuoh Town, and in the Netherworld.

Despite being in separate locations, the two girls’ words overlapped with miraculous timing.

**~ Meanwhile, with the Double Switch Princesses - End ~**

In any case, the Nyuu-power inside me has stabilized!

However... strangely enough, the moment we docked, the damage my body had taken vanished.

Not only that, my stamina has fully recovered.

What on earth...

As if reading my confusion, Sensei sent a transmission.

『Listen. The Oppaiser is loaded with the breast milk you squeezed from Alice and Rias. Thanks to that, you should have regained your strength.』

”Seriously?! It has that kind of function?!”

『Well, Ignis was the one who proposed it. I’m surprised it actually restored you. However, let me say one thing: that recovery can only be used once per docking. In other words——』

Ignis finished Azazel-sensei’s sentence.

『In other words, every time you use it, you have to squeeze Alice-chan and Rias-chan’s boobs♪』

Wh-Whaaaaaaaaat?!

I have to milk their boobs every time I dock?!

I have to drag them into the ”Restroom” again?!

Th-That actually feels like a pretty happy bonus...

I’ll probably get hit with an Alice Punch, but maybe that’s okay too...

Uh, when I get home, maybe I’ll ask them again...

As I was imagining the cute and erotic sight of the two of them, Azazel-sensei gave me additional information.

『Listen up. The Oppaiser is merely a device to stabilize your Nyuu-power. The duration of that state isn’t much different from your normal EXA form. Well, the output itself might be higher, though. Anyway, this is a battle until your stamina runs out. Be careful, because if your stamina hits zero, the docking will disengage.』

”It disengages? It’s not like the artificial Sacred Gear of the Sitri peerage?”

『The Oppaiser does utilize artificial Sacred Gear technology, but it is similar yet distinct. Furthermore, since it’s a unique item designed exclusively for the EXA form, it cannot be used with other forms.』

Ah, I see.

Well, it is just a ”Pectoral Power Stabilization Support Device,” after all.

If I think of it that way, I guess it makes sense...

Sensei continued.

『Our battle over here is going smoothly so far. But I feel bad that we can’t send reinforcements from the Underworld or Heaven...』

”It’s fine. We’ll handle things over here, so Sensei, please watch over Rias and the others. ——I’m gonna slam a hit into this guy, too.”

I shifted my gaze to Asem, who was looking up at me from below.

He was still wearing that smirk.

I took a deep breath and——.

”Here I go, Asem! This is Round Two! Ddraig!”

『Yeah! It’s a shame about a lot of things, but right now, you can use it! Do it, Partner!』

I got permission from Ddraig!

I promoted the pawn inside me to ’Queen’!

At the same time, using the promotion enhancement, I synchronized the power of this form and the piece to the highest level!

”——Trans-am!”

『Trans-am Drive!!!!』

A powerful voice rang out from the gauntlet’s jewel!

My armor turned red——emitting a crimson radiance, and a massive amount of sparkling red particles were released from my widely spread wings!

I pointed a finger at Asem and shouted.

”EXA—no, Double Oppaiser! Take everything I’ve gotttttttttt!”

Releasing red particles, I nose-dived!

I charged at Asem with speed far surpassing EXA!

In response, Asem thrust out his black gauntlet, showing me his biggest smile of the day!

”Aha♪ That’s it, that’s it! Show me your new possibilities!”

Entering Round Two with the God from another world!

When our fists collided, our auras sparked violently against each other!

The resulting lightning began to destroy the surroundings!

”Zeeeeeeeaaaaaah!”

”Ahahahahahahahaha!”

My roar mixed with Asem’s laughter.

Space began to distort around our clashing fists, creating a vortex.

The ground cracked, the clouds warped, everything being pulled into the vortex!

The moment the peeled-up ground began to float, Asem and I flew backward as if repelled.

Simultaneously, the spatial distortion subsided, and the floating debris fell back down, pulled by gravity.

I spread my wings, kicked off a piece of falling debris, and dashed forward.

Drawing a trail of light, I zigzagged through the air and swung at Asem!

Asem, flashing a smile from beneath his hood, created countless afterimages.

All of the afterimages aimed their palms at me, concentrating black aura.

”Now, can you see through this?”

As he spoke, every single one of Asem’s afterimages fired energy blasts!

The number of blasts far exceeded one or two hundred!

Judging by what Asem said earlier, some of these must be dummies.

Illusions mixed in with the real ones.

But every single energy blast feels dangerous; I can’t tell them apart!

If I can’t tell them apart——.

”I’ll just shoot them all down!”

I condensed my body, gathering power, and——unleashed it all at once!

A shockwave expanding in all directions!

The red wave canceled out the black spheres, causing a massive explosion in mid-air!

The entire sky became a sea of fire!

Scattering red particles, I flapped my wings and charged straight through the sea of fire.

Emerging from the roaring flames was Asem!

He must have charged through the fire as well; he was closing in at tremendous speed!

Fist clashed with fist once again!

Boiling with crimson aura, I launched a rush of attacks!

Asem wore a smile of composure, dodging everything——or so it seemed.

Looking closely, there was a cut on his cheek, blood seeping out.

Also, his trademark white hoodie was torn in places.

That means——Asem is starting to fail to dodge my fists completely.

His body, which hadn’t taken a scratch until now, is slowly unable to keep up with his reactions.

As for me, while I am taking hits from Asem, the damage I’m receiving has decreased significantly.

Moreover, the number of hits I’m taking has dropped drastically.

And then——.

”Oooooooooh!”

”Gh...!”

My fist buried itself in Asem’s cheek.

My attack finally captured Asem completely.

The fist that couldn’t reach him in EXA form had finally connected.

”I’m gonna push you back all the way!”

The boosters on my gauntlets spewed fire.

They were miniaturized boosters, but their output was higher than before.

Before my power stabilized, I was probably leaking energy wastefully.

Now that it’s stable, I can concentrate that power.

And in this Trans-am state, my speed and power are tripled!

My fist, gaining momentum, sent Asem flying far into the distance!

I moved to pursue immediately.

But, as expected of Asem.

Releasing power, he performed a mid-air somersault.

He regained his posture in the air.

Asem wiped his cheek and laughed.

”Yup, this is beyond my expectations! Is this Oppai Power?”

”That’s exactly right!”

In the end, it is boobs!

I can’t deny it!

Alice-san!

Rias-san!

...Thank you for your boobs!

Allow me to thank you from the bottom of my heart!

If I make it back safely, I’m going to hug both of them!
