Kahaku の物語

Kahaku の挿絵付き昔話バナー

In the mist-shrouded valleys of our mountains, where the rivers wind and twist like living serpents, there dwelled a Kahaku with a heart as green as the first sprouts of spring. His name was whispered in awe by the villagers, who would offer him cucumbers at the riverbank crossings, lest he grow displeased and stir the waters to fury.

Our village lay nestled between two great rivers, their currents strong and capricious. It was said that on moonless nights, when the water's surface seemed to shimmer like a sheet of molten silver, you could hear the Kahaku's mournful calls echoing across the rapids. Some claimed it was a warning, while others believed he merely beckoned those who would join him in his eternal vigilance over the waters.

One summer, as the heat bore down upon us, a young boy named Kaito wandered too close to the river's edge. His laughter and shouts of joy carried far and wide, until they reached the ears of our resident Kahaku. The spirit gazed out from beneath the water's surface, his beak-like mouth curving downward in a sorrowful line.

For Kaito was not just any child. He was born with a peculiar gift: an uncanny understanding of the river's moods and whispers. As he stood there, entranced by the rippling currents, the Kahaku sensed something familiar – a kinship that went beyond mere human and spirit. It seemed that this boy had been chosen to bear witness to the secrets of our watery world.

The villagers would tell you that on certain evenings, when the sun set over the mountains like a burning brand, Kaito's laughter would be answered by the Kahaku's haunting call. The villagers believed it a summons – an invitation for the boy to join the spirit in his eternal vigilance over the rivers.

One night, under a moon hidden behind thick clouds, I chanced upon Kaito at the riverbank. His eyes shone like polished jade as he leaned forward, listening intently to some unheard melody. The water's edge lapped against his toes, and I saw then that he was not alone. For on the boy's head, a small dish had appeared – just like those carried by our Kahaku.

In that moment, as the world seemed suspended between the ebb and flow of life, I beheld the Kahaku himself rising from the depths. His greenish skin glistened with dew, his webbed limbs rippling like living water. For an instant, our gazes met – a connection sparked between two souls bound to the river's mysteries.

As the night wore on, and the stars struggled through the veil of clouds, Kaito vanished into the darkness. Some say he was taken by the Kahaku, to be initiated into the secrets hidden beneath the surface. Others claim that the boy remains to this day, guarding the rivers as a sacred sentinel, his laughter mingling with the Kahaku's mournful calls in an eternal duet.

In our village, we whisper of Kaito and the Kahaku, who walked between worlds and shared the burdens of their watery realm. And on moonless nights, when the wind stirs the reeds and whispers secrets to the river's edge, some still say you can hear the call – an invitation from a guardian spirit, echoing across the rapids, beckoning you into the heart of our mist-shrouded valleys.
