Shane had some understanding of the Moon Demon Sela.
It was said that in the Divine Race, there existed a Sun Goddess who presided over light and warmth, but no Goddess of the Moon.
Thus, since ancient times, people have believed that the moon was under the dominion of the Moon Demon Sela.
Because the Moon Demon was the eldest of the Six Great Demons, and the first under the Demon King, her status among the Demon Clan was incredibly lofty. Even the other five Demons willingly revered her and would generally cooperate with the directives of this Moon Demon.
Furthermore, this Moon Demon had power rivaling that of a Demon in her normal state. If it were a night of a full moon, her power would surge drastically, reaching a level where even the Fate Goddess Lidas, who was said to be the closest to omnipotence, could only gain a slight advantage.
