G-G-G-Ghosts!?

Story

"As suspected, there was no ghost. Only illusion magic."

Kizeri complained that ghosts were appearing in a cave he planned to use for storage.

To help the frightened Shugo, you decided to investigate the strange phenomena inside the cave.
The cave was filled with distorted traces of illusions, and at its center lay a shattered barrierstone.
When you touched the barrierstone, an illusion of Reda appeared—proof that she had once stayed there.

Though you could not determine what Reda was doing there, at least you confirmed there were no real ghosts. For now, the Shugo's ghost scare has been put to rest.
