Akki の物語

Akki の挿絵付き昔話バナー

In the depths of the mountain village, where the air was heavy with mist and the trees creaked with an otherworldly voice, there lived a young blacksmith named Kaito. He was a skilled craftsman, renowned for his strong arms and steady hands, but Kaito's true passion lay in hunting. Every full moon, he would slip away from the village to track the elusive yuki-onna that roamed the mountain's frozen peaks.

Kaito's love of hunting was not without consequence, however. His wife, Emiko, had grown weary of his nocturnal excursions and the dwindling firewood supply left in their wake. She would often whisper prayers to the kami, begging for her husband's safety and a return to responsible behavior.

One night, as Kaito ventured deeper into the mountains than ever before, he stumbled upon an eerie sight: a massive Akki crouched at the edge of a frozen lake, its red skin glistening like polished lacquer. The air seemed to ripple with malevolent energy as the creature's wild hair danced in the wind.

Kaito froze, his hand instinctively reaching for the iron club slung over his shoulder. He knew better than to engage an Akki, but something about this one drew him in – perhaps it was the glint of recognition in its fanged maw or the faint scent of smoke and sweat that clung to its pelt.

The Akki's eyes locked onto Kaito, and for a fleeting instant, he felt the weight of his own karma settle upon him. He recalled Emiko's words, whispered in sorrow: "Your love of hunting will be your undoing." The blacksmith's heart quickened as the creature began to rise, its massive frame unfolding like a dark, twisted tree.

As Kaito turned to flee, he heard the Akki's voice, low and rumbling, like thunder on a summer day. "You have chased yuki-onna through these mountains for years," it growled, "yet never considered your own shadow." With that, the creature swung its club in a wide arc, sending Kaito tumbling across the frozen lake.

When he stumbled to his feet, Emiko's words echoed within him: "Your love of hunting will be your undoing." He saw the Akki looming over him once more – but this time, it spoke not with anger, but with sorrow. Its voice was a gentle breeze that rustled Kaito's hair, carrying the weight of countless souls who had succumbed to their own vices.

The blacksmith realized that his love of hunting had blinded him to the harm he caused, and in that instant, something within him shifted. The Akki's club, once a symbol of punishment, now seemed a reminder of the consequences of one's actions. Kaito knew he would never hunt again – not for any creature, nor for any thrill.

As the sun began to rise over the mountains, the Akki vanished into the mist, leaving behind only its shadow on the frozen lake. Kaito returned to his village, changed forever by the encounter with the embodiment of chaos and punishment. From that day forward, he spent his days forging tools for the village's farmers, his nights spent tending the fire that warmed their hearths – a small act of redemption, in the presence of the Akki's unyielding gaze.
