High School DxD: Aeon of Time

- A Few Moments Later -

After cleaning themselves up, Aeon and Iris performed another Time Skip. This time, they arrived in a void beyond dimensions—a place accessible only to the highest entities. It was here that the Infinite Dragon God, Ophis, would be born.

As before, Aeon conjured a magnificent throne made of pure energy. Its design was simple but exuded absolute power. However, this time there was a different sight—Iris, with her unmatched grace, sat comfortably on Aeon's lap. Her expression radiated a softness reserved only for him, her gaze reflecting pride and tranquility.

The initially silent void began to change. Infinite energy surged from all directions, creating fluctuations that shook the very fabric of reality. The once-stable space vibrated, producing crackling sounds akin to shattering glass.

The cracks spread rapidly, forming intricate patterns that shimmered with a dark purple glow. Within seconds, they widened into a massive fissure that emitted a blinding light. From this rift emerged a small infinity symbol, glowing like a star. It rotated slowly, growing larger until it filled almost the entire void.

But the symbol began to destabilize. Tiny cracks appeared on its surface before it exploded into fragments of light, revealing a majestic figure. From the center of the void, the body of a massive black dragon gradually took shape.

Its scales glimmered with a dark purple sheen, as if each scale reflected infinite dimensions. Its pitch-black eyes were endless voids, with a glowing infinity symbol in the center of each iris. Its jet-black wings stretched magnificently, enveloping the space as if asserting its dominance over reality itself.

The dragon gazed at the throne, observing the two figures seated upon it. Tilting its massive head slightly, it displayed an expression of confusion—oddly adorable despite its colossal and imposing form.

Aeon chuckled softly at the dragon's curious behavior, while Iris smiled gently, as though she knew what was to come.

However, Aeon's laughter seemed to annoy the dragon. It furrowed its brows and let out a low growl, signaling its displeasure. Before the dragon could roar in frustration, Aeon spoke in a calm yet authoritative tone.

"Try transforming into a form like ours," he said, his voice soothing yet irrefutable.

The dragon hesitated for a moment before bowing its head slightly. A dark purple glow enveloped its massive body, rapidly shrinking it. When the light faded, where the great dragon once stood, there was now a small girl, appearing to be around 13 years old.

Her long black hair flowed gracefully down her back, and her pitch-black eyes, adorned with glowing infinity symbols, shone like stars. Her pale, flawless skin radiated an aura of eternity. However, the situation turned slightly awkward—she was entirely unclothed.

- Aeon's POV -

I looked at the little girl and couldn't help but smile. Her human form perfectly matched my expectations—simple yet radiating the limitless infinity she embodied.

Beside me, Iris observed the girl with a gentle smile that warmed my heart. I knew she was just as pleased with the result.

Without further delay, I conjured a robe from pure energy and draped it over her small frame. "Alright, little sister, allow me to introduce myself," I said proudly. "I am your great brother, Alexander Aeon, the Primordial God of Time and Space."

I turned to Iris, who still sat gracefully on my lap. "And this is your elder sister, Iris."

Iris smiled and raised her hand with elegant poise. "Hello, little one~ Fufufu~" she said in a voice full of tenderness and affection.

The girl—whom we now called Ophis—stared at us with a confused expression, her small brows furrowing as if she was trying to grasp the situation.

- Third-Person POV -

Ophis attempted to speak, but all that came out were indistinct murmurs. "Aa... A..."

Seeing this, Aeon gently patted her small head. "It seems she hasn't learned how to speak properly yet," he remarked with a soft smile.

Iris chuckled lightly. "Fufufu~ Ophis is different from Yahweh. She was born without receiving basic knowledge. In other words, she's truly like a newborn baby~"

Aeon nodded and then looked at Ophis. "In that case, let me give you a little help," he said, placing his hand on her head. A soft glow emanated from his palm, transferring basic information into the little girl's mind.

After a moment, Ophis lifted her head and looked at Aeon with shining eyes. "Brother?" she asked, tilting her head in innocent curiosity.

Aeon's smile widened. "Yes, I'm your brother! And you should call me onii-chan!"

Ophis tried repeating the word. "Nii-chan?"

"Exactly!" Aeon exclaimed enthusiastically, his smile growing even broader.

With a cheerful expression, Ophis hugged Aeon tightly. "Nii-chan!!" she said sweetly, her voice capable of melting anyone's heart.

Watching this, Iris approached them gracefully and gently took Ophis from Aeon's embrace. "Ophis-chan~ Call me nee-chan, okay?" she said with a warm smile.

Ophis looked up at Iris and innocently said, "Nee-chan?"

"Fufufu~ That's perfect! Ophis-chan is absolutely adorable!" Iris declared, hugging her little sister tightly.

- Third-Person POV -

Time passed quickly for the three of them. After introducing themselves and giving Ophis basic information, Aeon and Iris started teaching her various things. Despite being newly born, Ophis had an incredible ability to learn due to her essence as the Infinite Dragon God.

They began with basic knowledge, like language and simple world concepts. Iris, with her endless patience, took on the role of a gentle teacher. She often taught Ophis through short stories she created herself, full of meaning and life lessons.

On the other hand, Aeon handled more serious aspects. He taught Ophis advanced magic, energy manipulation, and martial arts. Each lesson was conducted with seriousness, but Aeon ensured Ophis enjoyed every moment.

In between training, the three often played together. Ophis's cheerful laughter filled the void, bringing joy to the otherwise empty space. Iris and Aeon cherished every moment, feeling that Ophis's presence brought a happiness they hadn't realized they were missing.

However, one unique trait of Ophis remained unchanged. When not with her siblings, she reverted to her usual blank and indifferent expression, reflecting her nature as a representation of infinity—untouched by typical human emotions. Yet, in the presence of Aeon and Iris, Ophis showed a much warmer side, with smiles and laughter that often left them captivated.

100,000 Years Later

Amidst the boundless void stood a traditional Japanese-style house—majestic yet simple. The house seemed out of place in such a setting, but for the three of them, it symbolized peace and family bonds.

Inside, the atmosphere was calm and cozy. Aeon sat cross-legged on the floor of the main room, holding Ophis in his lap. Ophis was happily munching on cakes made by Iris, her small hands carefully gripping a piece while her face radiated satisfaction.

In the kitchen, Iris was preparing more food. Occasionally, she glanced toward Aeon, Yahweh, and Ophis with a gentle smile, feeling content seeing her younger sibling enjoy her cooking.

Yahweh sat beside Aeon, his glowing rainbow-colored eyes closed, wearing his usual calm expression.

In the peaceful silence, Aeon suddenly opened his eyes and smiled. "She's born," he said in a mysterious tone.

Yahweh slowly opened his eyes, revealing his rainbow pupils gently spinning like the wheel of time. "Yes, Brother," he replied with a small smile.

Soon, Iris entered the main room carrying a tray full of cakes. Before she could set it down, Ophis quickly grabbed a piece and cheerfully said, "Thank you, Nee-chan!"

Iris couldn't hold back. She immediately swooped in and scooped up Ophis, stealing the little girl from Aeon's lap. "Aaa! My little sister is so cute!" she exclaimed, pressing her cheek against Ophis's, making the girl giggle.

"Hahaha, it tickles, Nee-chan!" protested Ophis through her laughter.

Aeon could only shake his head with a small smile. "She's truly become a huge siscon," he thought.

After a while, Iris finally released Ophis, allowing her to return to Aeon's lap. With a curious expression, Ophis asked, "Nii-chan, who's going to be born?"

Aeon gently stroked her black hair while looking at her fondly. "Our youngest sibling," he replied with a smile. "Dream."

Ophis tilted her head, her confusion evident. Before she could ask further, Yahweh stood up, his smile widening. "We'll meet her soon, Brother," he said.
