Freya was momentarily in shock at the sudden revelations, she approached Daimon in a matter of seconds, which made Rita who was observing everything thoroughly from Daimon's shadow, prepared to protect her young master on the spot.
But Daimon transmitted his intentions to her, which were not to act unless Freya showed hostility after realizing he wasn't the "hero" from the Mermen Sea, which they now knew was as much of an asshat as Adam, but with a bit more of luck, since he lived until he reached the Stellar ranks, not one but twice.
The fact that Freya reacted to the vertical lines in Daimon's pupils, the trait gained thanks to the Black Armored Shark's lineage, combined with the trident of the storm being the item that acted as the secondary legacy left for Adam, made it clear that the though the hero only showed to have darkness affinity in the records of Neptune, he used to have water affinity before.
