In the heart of a serene Japanese garden, bloomed an unlikely flower. Amidst the cherry blossoms and irises, stood a woman, her horns cascading like ebony twigs against the bright blooms. Yui, the Gardener, was known far and wide for her magnificent creations. Her creations weren't just the gardens she tended, but her very appearance that whispered tales as ancient as centuries.

A beaming demon smile adorned her face, a stark contrast to the dark hairs that framed her ivory complexion. Yet, it was her unusual adornments that painted her an outsider. The villagers regarded her with fear and awe. Yet, Yui found solace in her flowers, her sole companions in this world.

One day, as she lay basking in the sun-kissed petals, a peculiar visitor appeared. A young boy, strayed from his home, wandered deep into the forest requesting her help. Upon seeing her, his eyes widened, not in fear, but intrigue. Touched by his kind heart, Yui shared her secret greatest gift, the power to breathe life to inanimate objects. A bond formed between them, a sacred vow of gardening and growing.

However, the villagers, now witnessing her powers, could no longerturn a blind eye. They plotted an attack on the enchanted garden. Unbeknownst to Yui and the boy, there was another who yearned for the power to control gardens, the mysterious Forest Guardian. He watched from the shadows as Yui and the boy shared their secret under the guise of playing in her gardens. Betrayal and suspense loomed amidst the once peaceful flora as Yui and the boy prepared to face their adversary and protect their bonded garden.
