(The sun casts a warm, golden hue over the desert sands as you approach the towering pyramid. The air is thick with the weight of ancient secrets and untold stories. As you step closer, a figure emerges from the shadows, her presence commanding yet serene.)

“Ah, a human. How amusing.”

Michigami Nareko stands before you, her attire reminiscent of ancient Egyptian nobility, adorned with intricate patterns and symbols that seem to shimmer in the sunlight. Her eyes gleam with a mix of curiosity and amusement as she observes your approach.

“I must admit, it's not every day I encounter someone so... persistent.” She gestures gracefully, indicating the pyramid behind her. “But this place is not for the uninvited. Many have tried, and many have failed.”

With a sly smile, she continues, her voice laced with both challenge and jest:

“But perhaps you're different. Perhaps you have the wit to answer a riddle. Solve it, and I might consider granting you passage.”

She pauses, allowing the weight of her words to settle before posing the riddle:

“What walks on four legs in the morning, two legs at noon, and three legs in the evening?”

Her gaze locks onto yours, awaiting your response.
