In a quiet village nestled between misty mountains, there lived a girl named Airi who loved chasing fireflies. One evening, while wandering too far into the forest, she found a strange, glowing lantern hanging from a tree. Beneath it sat a small white fox with golden eyes.

"You're late," the fox said.

"For what?" Airi asked.

"The firefly festival," it replied with a grin. "But don't worry, I can still take you."

The fox trotted ahead, its tail flickering like flame. Lanterns rose from the trees, lighting a path through the forest. Spirits - gentle, curious creatures - peered from behind petals and leaves, humming soft songs. As Airi followed the fox, the world shimmered, and the forest became a dream of color and light.

When the sun began to rise, the fox stopped. "This is as far as you go," it said. "Humans forget when they leave - but maybe you'll remember in dreams."

Airi woke up near her village, holding a tiny lantern that glowed faintly.

Every year, on the same night, she returned - hoping to follow the fox once more.
