Solomon's Ring: Hi no Shou

Otome game by Plan Peace. The first in the Solomon's Ring series.

Based on the Legend of Solomon, who was known to be the third king of the Israelites, who built the Temple of Jerusalem, and who was said to possess a magical ring that had the powers to control demons.

He soon saw the dangers of their arrogance, and sealed them all into a brass vase. Approximately 2500 years later, a certain demon, Lucifer, has taken the reins to be the most powerful demon. He turned his extreme hatred for Solomon into dark magic, and successfully released the seal upon the brass vase.
