High School DxD: “The future Harem King”

As Su Hai finished gathering the last of the Magic Crystals with the help of the Tiona sisters, he adjusted the two large sacks slung across his back. The weight was substantial, but thanks to his enhanced strength, it posed little challenge.

Still, the curious glances from the Loki Familia members lingered.

"Hestia Familia?" Finn repeated with a raised brow.

"I thought Lady Hestia didn't have any members yet. Could it be…?"

Though surprised, Finn quickly pieced together the situation.

Confirming the Truth

"That's right," Su Hai replied calmly. "I only arrived in Orario recently. I was fortunate enough to meet Hestia and became the first member of her Familia."

Despite Su Hai's straightforward response, the Tiona sisters exchanged skeptical glances.

"Brother Su Hai, stop joking!" Tiona said, her eyes wide with disbelief. "Are you seriously telling us you're only Level 0?"

"And you can fight like that?!" added Tione, equally stunned.

Even Finn, who had already suspected the truth, couldn't help but feel a surge of astonishment upon hearing Su Hai's confirmation.

However, the one whose reaction stood out the most was Ais Wallenstein—the golden-haired Sword Princess. Her gaze lingered on Su Hai, her amber eyes reflecting a flicker of intrigue, as if she had just discovered a long-sought answer to an unspoken question.

Invitation to Return Together

After a moment of silence, Finn stepped forward, regaining his composure.

"Well, Brother Su Hai, it's already getting late," he said. "Why don't you come back to the surface with us? It's safer to leave the dungeon in a group—especially when carrying that much loot."

"Yeah, come with us!" Tiona added enthusiastically, her lively demeanor making it clear that she had taken a liking to Su Hai.

Even Riveria and Bete nodded in agreement. Though their personalities differed, both respected strength—and Su Hai had certainly proven himself.

Su Hai's Decision

Su Hai glanced at the time and realized that the day had indeed grown late. If he stayed any longer, Hestia would undoubtedly start to worry. Moreover, carrying two large sacks of Magic Crystals alone would certainly attract unwanted attention in the city.

"Alright, I'll take you up on that offer," he replied with a smile. "Thank you for the help."

Curious Amazon Sisters

As they made their way through the dungeon's upper floors, the Tiona sisters—both known for their bold and outgoing personalities—couldn't contain their curiosity.

"Brother Su Hai, are you really just an ordinary human?" Tiona asked, walking closely beside him. "You don't have dragon blood or come from the Giant Clan, do you? I mean, how else could you be so strong?"

Before Su Hai could answer, Tione stepped forward and placed her hands on his arms, squeezing lightly as if trying to test his muscles.

"Right? Look at these arms—how are they so firm and powerful?!" she exclaimed with fascination.

"Hey! Don't grope the poor guy!" Finn interjected, shaking his head with an exasperated sigh. "Give him some space, will you? He's not one of your sparring partners."

The sisters exchanged playful glances, clearly unwilling to stop, but they eventually relented.

"Fine, fine… But we still want to know your secret!" Tiona said with a pout.

Emerging from the Dungeon

Before long, the group emerged from the dungeon's entrance and stepped onto the bustling streets of Orario, where the setting sun cast long shadows across the city.

Stopping in the square outside the dungeon, Finn turned to face Su Hai.

"It was a pleasure meeting you, Su Hai. We need to report our expedition's results to Lady Loki, but if you ever need anything, don't hesitate to visit our Familia's headquarters."

"Yeah! Don't forget us, Brother Su Hai!" Tiona called out with a grin, waving her hand cheerfully.

"See you around!" Tione added with a wink.

Ais Steps Forward

Just as the group was about to leave, Ais Wallenstein took a step forward, her gaze fixed intently on Su Hai.

"Su Hai…" she said quietly. "Can you tell me why you're so strong?"

Her expression remained neutral, but there was a hint of longing in her eyes—an unspoken desire for something beyond her reach.

Finn's eyes widened slightly in surprise, and Riveria's gaze flicked to Ais with a knowing look.

They all understood—Ais had long sought to grow stronger, her drive fueled by something deeply personal.

Su Hai's Offer

Su Hai considered her question for a moment.

In truth, his strength came from the Golden Egg System—something he couldn't share with anyone else. But his other abilities—such as Thunder Breathing and Reinforcement Magic—were techniques that could be learned through training.

And besides, he genuinely respected Ais' dedication to improving herself.

"Well… I do have some techniques that help me grow stronger," he said at last. "If you're interested, you can visit the Hestia Familia sometime. I'd be happy to teach you what I know."

Ais' eyes lit up with a faint spark of excitement, though her expression remained as calm as ever.

"Thank you… I will."

Surprised Reactions

Finn, who had been about to intervene, fell silent. He had expected Su Hai to refuse—after all, an adventurer's training methods were usually closely guarded secrets.

Yet this boy, who had just demonstrated strength beyond most Level 5s, had offered to share his techniques without hesitation.

Riveria glanced at Su Hai with newfound respect, while Gareth stroked his beard with an approving smile.

Tiona's Complaints

However, not everyone was pleased.

"Brother Su Hai, you're playing favorites!" Tiona protested, crossing her arms with an exaggerated pout. "We helped you pick up all those Magic Crystals, but you only offered to teach Ais! That's not fair!"

"Yeah, what's so special about Ais, huh?" Tione added teasingly. "You've got a crush on her or something?"

Su Hai could only smile helplessly at their antics.

"If you're that interested, you're welcome to come to the Hestia Familia as well," he replied with a shrug.

The sisters exchanged gleeful grins, clearly satisfied with his answer.

Parting Ways

As the group prepared to leave, Finn stepped forward one last time, resting a hand on Su Hai's shoulder.

"Take care of yourself, Su Hai. With your strength, you have the potential to become one of Orario's greatest adventurers. Don't let that potential go to waste."

"Thank you, Captain Finn. I'll do my best," Su Hai replied sincerely.

With that, the Loki Familia turned and walked toward their headquarters, their figures disappearing into the crowd.

Su Hai watched them go, a faint smile on his lips.

Though their meeting had been brief—

Something told him that their paths would cross again.

And next time—

He would be even stronger.
