Despite his vantage point and keen observation skills, Rain couldn't discern Iori's silhouette among the dragons in the water. While he could see the outlines of the dragons submerged underwater, Iori's figure escaped from his sight, shrouded in mystery and obscured from his view. This prompted Rain to heighten his vigilance, realizing that Iori's stealth or concealment techniques might prove challenging to detect even from a distance.
"I considered that he wouldn't be among them, but…" Rain furrowed his eyebrows. "He will probably join them before the battle starts."
Rain chose to maintain his position, flying stealthily above the ocean's expanse, waiting patiently for any developments or signs of movement among the dragons gathered below. Despite his concealed position, he remained vigilant, keenly observing their actions and interactions.
