Gremory Mansion – Private Training Grounds

A thunderous explosion shook the training field, sending debris flying as a streak of red-black energy tore through the air. The sheer force of it left deep cracks in the earth, disintegrating a stone target instantly.

Naruto lowered his hand, crimson eyes gleaming with excitement.

"So this is Bael magic, huh? No wonder people fear it."

The Power of Destruction felt different from chakra. It wasn't something he had to carefully mold like a Rasengan. No, this was raw annihilation—a force that simply erased whatever it touched.

"Impressive," Akeno purred from the sidelines, her violet eyes filled with intrigue. "For someone who supposedly lacked Bael's talent, you're already better than most noble devils."

Naruto rolled his shoulders. "What can I say? I learn fast."

Akeno chuckled. "Oh, I like that confidence, Naruto-kun. But magic isn't just about brute strength. Can you actually control it?"

Naruto smirked. "There's only one way to find out."

[System Notification]

Training Grounds – One-on-One Combat

Akeno stepped forward, lightning sparking at her fingertips. The wind shifted as her aura surged, her playful demeanor still present but now laced with deadly intent.

"I won't go easy on you," she teased, electricity crackling around her hands. "After all, you did say you wanted to test your limits."

Naruto grinned. "Bring it, thunder princess."

The fight began.

Akeno struck first, raising a hand as bolts of blue lightning roared toward him like a divine judgment.

Naruto reacted instantly.

"Demonic Eruption!"

A concentrated blast of destruction magic collided with the incoming lightning, creating an explosive shockwave that sent both attacks dispersing in midair.

Akeno's eyes gleamed. "Not bad~"

She flickered out of sight.

[DANGER!]

Naruto barely sidestepped as she appeared behind him, her fingertips sparking with electricity.

SHZZZTT!

Lightning grazed his arm, numbing the limb temporarily. He gritted his teeth—if she had landed a direct hit, he would've been paralyzed.

"Time to test something new."

He focused his demonic energy, forcing it outward instead of in a straight blast. The power of destruction swirled around him, forming a barrier of annihilation just as Akeno attacked again.

Her lightning blast evaporated on contact.

Akeno's eyes widened in surprise. "You just made a Demonic Barrier in your first fight?"

Naruto smirked. "Like I said—I learn fast."

Akeno chuckled. "Then let's push you further."

She lifted both hands, and suddenly, the sky darkened.

Thunder rumbled overhead, swirling storm clouds forming as she prepared a massive attack.

Naruto's System chimed.

[New Skill Unlocked: "Demonic Barrier"]

• Generates a protective field of Destruction energy.

• Can be upgraded to absorb and counter attacks.

Naruto's instincts screamed.

"I need to end this before she fires that off."

His crimson eyes flashed as he took a deep breath, channeling every bit of magic into his palm.

"Try handling this, Akeno—"

"Demonic Burst!"

A compressed sphere of destruction energy shot forward, moving faster than any of his previous attacks.

Akeno's lightning roared to meet it—

BOOOOM!

The explosion sent dust and wind flying in every direction. The entire training field shook, and when the smoke cleared—

Akeno stood, slightly bruised, her outfit lightly singed.

She licked her lips. "Oh, Naruto-kun~ That was deliciously dangerous."

Naruto, panting slightly, smirked. "Guess I pass?"

Akeno walked closer, standing just inches from him. "More than pass. You're a natural at destruction magic."

Then, in a move that shocked the onlookers—

She ran a finger down his chest, her touch electric.

"Maybe we should have a more… private training session sometime?" she teased.

Naruto blinked, momentarily caught off guard. "Did I just unlock the Harem Route?"

Akeno giggled. "Maybe."

Rias's voice interrupted them. "That's enough flirting, Akeno."

Akeno pouted. "Oh, but Rias~ He's so much fun to tease."

Rias sighed before turning to Naruto. "You've proven your strength, but you still need proper training. That's why I'm taking you to the Underworld tomorrow."

Naruto's smirk faded slightly. "The Underworld, huh?"

Rias nodded. "You need to see what you're up against. And if you plan to challenge noble houses for power…" Her eyes glowed slightly. "…then you'll need more than just magic."

Naruto's grin returned. "Fine. Let's see what the Underworld has to offer."

As the group dispersed, Akeno leaned in one last time.

"Don't keep me waiting too long, Naruto-kun~" she whispered, before disappearing with a flash of lightning.

Naruto exhaled, running a hand through his hair.

"Okay. So I just fought one of the strongest girls in this world, leveled up, and unlocked the harem route…"

His System chimed again.

Naruto smirked.
