Once, in the realm of Takamagahara, where ethereal rivers flowed like liquid light and mountains shimmered with gold and silver hues, there lived a young
Tennin named Sarutahiko. He was unlike his celestial kin, for his wings were of pure amber, edged with fiery hues, as if touched by the sun itself. Sarutahiko was known not just for his striking appearance but also for his boundless curiosity, which often led him to venture beyond the lofty bounds of Takamagahara.
In the center of the heavenly plane, there burned the
Eternal Flame, a source of divine light said to grant balance and life to all worlds. Guarded by the Council of Radiance, this flame had burned since the dawn of creation, its mysteries known only to the gods who dared not reveal its origin. Yet a prophecy lingered among the Tennin - a young soul born of fire and curiosity would either protect or extinguish the flame forever.

In an ethereal courtyard filled with history, this resolute warrior stands ready, embodying strength and bravery against a backdrop of ancient stone that tells stories of valor and courage.
Sarutahiko grew up on whispered tales of the flame's origin. It was said that it held the memories of every being who had ever lived, a flicker of their existence woven into its endless light. To Sarutahiko, the flame was more than a symbol of divine balance; it was a puzzle waiting to be solved. Though warned to respect its sanctity, he longed to uncover its secrets.
One evening, as the stars began their celestial dance, Sarutahiko climbed to the highest peak of Takamagahara, where the Eternal Flame hovered within a temple of translucent quartz. The temple was encircled by nine towering gates, each one inscribed with glyphs of binding magic. The air around the flame pulsed with an unyielding force, a silent warning to any who approached unbidden.
But Sarutahiko was undeterred. He carried with him a shard of
Hisui, a sacred jade said to reveal hidden truths. Holding it to his eye, he gazed at the flame. Through the shard, he saw more than light; he glimpsed shifting images of battles, love, despair, and hope. The flame was alive, a repository of countless stories. And then, for the briefest moment, the flame seemed to whisper his name.
"Why do you linger, Tennin?"
Startled, Sarutahiko turned to see a figure step forth from the shadows. She was tall and cloaked in robes of twilight, her eyes as deep as the cosmos. It was Amaterasu, the goddess of the sun and keeper of the flame.
"You seek what none before you have dared. The Eternal Flame is not yours to understand," she said, her voice both stern and sorrowful. "To touch its heart is to risk unraveling the fabric of existence."
"But what if I'm meant to?" Sarutahiko countered, his voice trembling with determination. "The flame called my name. If it holds the truth of all things, then isn't it my duty to learn it?"
Amaterasu studied him for a long moment before gesturing toward the flame. "If the flame has chosen you, it will allow your approach. But know this: should your intent falter, even for an instant, it will consume you."
Sarutahiko stepped forward, his heart pounding like a war drum. As he neared the first gate, the glyphs shimmered and dissolved. One by one, the gates opened, until he stood before the Eternal Flame itself. The heat was unbearable, yet he felt no pain. Instead, he was enveloped by a cascade of voices and visions. Each flicker of the flame revealed a new truth: the birth of stars, the sorrow of forgotten deities, the ceaseless cycle of creation and destruction.
At its core, he saw a shadow - a dark ember that pulsed with a rhythm distinct from the rest. Intrigued, Sarutahiko reached out, and as his fingers brushed the ember, the flame surged. A voice boomed, ancient and resonant:
"Why do you seek me, child of amber?"
"I seek to understand," Sarutahiko replied. "If you are the source of all, why must you remain hidden?"
The ember flared, and the voice softened. "I am the spark of beginnings and endings. To know me fully is to bear the weight of eternity. Can you endure the burden of infinite knowledge?"
"I will try," Sarutahiko whispered.
The ember trembled, then released a surge of energy that flowed into him. Instantly, Sarutahiko's mind was flooded with revelations: the intricate dance of fate, the pain of choices made and unmade, the beauty and fragility of existence. He saw himself as a thread in a vast tapestry, connected to all that was and ever would be.
Yet as he absorbed the truth, he felt a growing despair. The weight of eternity threatened to crush him, and he realized the flame's warning was no mere test. To hold such knowledge was to risk losing oneself.
Just as he was about to succumb, a memory surfaced - a moment from his mortal past, long forgotten. A child in a small, sunlit valley had once gazed at the sky with wonder, dreaming not of answers but of endless possibilities. That child had been him. The memory rekindled his resolve.
"I will not let this knowledge consume me," Sarutahiko declared. "The flame is not meant to be possessed or understood in full. It is a beacon to guide, not a prize to claim."
At his words, the flame receded, and the ember returned to its place within the light. Sarutahiko fell to his knees, exhausted but alive. Amaterasu approached, her expression unreadable.
"You have done what none before you could," she said. "You sought the truth, not for power, but for understanding. The flame has tested you and found you worthy."
Sarutahiko's amber wings glowed brighter than ever, and he realized they now bore streaks of shimmering white - the mark of one who had touched eternity and returned.
From that day forth, Sarutahiko became the guardian of the Eternal Flame, not as its master but as its steward. He traveled between realms, sharing the light of the flame with those in need, yet never revealing its full truth. For he had learned that the beauty of existence lay not in knowing all but in the unending pursuit of wonder.
And so, the Eternal Flame burned on, a mystery eternal, entrusted to the one Tennin who had dared to seek its heart.
