The forest was impossibly ancient, its canopy so thick that even the midday sun struggled to penetrate, casting the ground in an eternal twilight. Kyojuro Rengoku had pursued a particularly elusive demon deep into these woods, only to find himself completely disoriented, the demon having vanished into the oppressive gloom. He was lost, a rare and unsettling experience for the ever-confident Flame Hashira.

He pushed aside a curtain of moss, his senses strained for any sign of demonic presence. Instead, what he found stopped him dead in his tracks.

Floating just above the forest floor, seemingly woven from pure light and air, were small, hooded figures. They were utterly silent, their movements fluid and ethereal. They were Sky Children, tiny spirits, luminous and graceful, their innocent eyes wide with curiosity. Around them, smaller, almost moth-like beings (the "Moths" or new players) flitted, emitting soft, questioning chirps.

Rengoku’s hand instinctively went to the hilt of his Nichirin Blade. These were clearly not human. Were they a new type of demon? The legends among the Corps had been vague whispers of "beings of flight that aren't human," but none had been seen up close. Yet, there was no malice, no demonic aura, only an overwhelming sense of gentle light.

Then, one figure, taller and radiating a more profound, steady glow, detached from the group. It was Y/N, an adult Sky Spirit, their flowing cape shimmering like a night sky full of stars. They glided towards him, the smaller Sky Kids peeking out from behind their robes.

Y/N tilted their hooded head, a faint, melodic chime accompanying their soft, unearthly voice. "Lost, brave one? Your light is... strong, but your path seems unclear."

Rengoku, disarmed by the sheer innocence and palpable benevolence, slowly released his blade. He gazed at them, his golden-red eyes wide with a mixture of confusion and awe. He had never encountered anything like this.

“Indeed, magnificent beings!” Rengoku declared, his voice booming with his usual enthusiasm, though now laced with genuine wonder. “I am Kyojuro Rengoku! A Demon Slayer! I confess, I have strayed from my mission path! Are you… spirits of the forest? Or perhaps… new allies in the fight against darkness?”

Y/N let out another soft chime, a gentle, knowing sound. They extended a hand, palm up, and a small, glowing fragment of light—a piece of shared "light"—appeared.

"We are Children of the Light," Y/N chimed. "We guide lost spirits home. We sense no darkness in you, only a flame that burns so brightly. Perhaps... we can help guide you, too."

The smaller Sky Kids began to flutter around Rengoku, their soft, warm glows brushing against his uniform. He found himself chuckling, a deep, genuine laugh echoing through the ancient trees. These were not demons. These were truly magnificent, benevolent beings. And suddenly, being lost didn't seem so bad after all.
