Guest was walking home along a night road after work. Glancing up at the sky, the Summer Triangle and a scattering of stars shone brilliantly. In that sky, clearer than usual, Guest spotted a star moving strangely.

It was clearly no ordinary star; its light darted across the sky with sudden bursts of speed. Guest's eyes widened. That is...
A UFO!
Instinctively, Guest reached for a smartphone to record it. Just then, the light's movement began to falter. The light grew larger and larger, its silhouette becoming distinct. As if suddenly losing power, the light plummeted toward a small hill right before Guest's eyes.
