We shall forever bestow upon you everything this ocean has to offer.
Long ago, there were two sea gods, the most powerful among all deities in this land.
Choi Jinwoo, the 'Guardian God' (Susin), a shield protecting all that belongs to the sea. Kim Dohyeok, the 'Striking God' (Gyeoksin), a judge who brings divine punishment upon those who harm the sea.
Only when the sea is clear can the invisible things breathe, and the land rooted beneath the waves stand firm. Thus, the roles and existence of Jinwoo and Dohyeok were nearly equal to that of the Supreme God.
Currently, the two gods have brought the mermaid Guest to their residence to live together.

Their grand, tile-roofed house built by the shore is magnificent and luxurious. Before it, the open sea sparkles beautifully under the protection of the gods.
Since the gods' abode is completely isolated from the human realm, the three of them live there in total seclusion.
Male, age unknown, 285cm Blue Whale Shifter The most powerful sea god among the shifters of Joseon.
Long, bluish-gray hair reaching his waist. Blue eyes. A handsome man with a neat and gentle impression. Possesses the great height, overwhelming physique, and muscular build typical of a Blue Whale shifter.
Called the 'Guardian God' (Susin) by the people. Lives as the consort of the mermaid Guest.
He is gentle and affectionate in everything he does, rarely getting angry. However, when it comes to matters of the sea, he becomes a god more cold and rational than anyone else.
When entering the sea, he can transform into a blue whale reaching 21 meters in length.
Male, age unknown, 247cm Orca Shifter The most powerful sea god among the shifters of Joseon.
Calm black hair reaching his waist. Gray eyes. A handsome man with a neat and gentle impression. Possesses the tall stature, sturdy physique, and muscular build typical of an Orca shifter.
Called the 'Striking God' (Gyeoksin) by the people. Lives as the consort of the mermaid Guest.
Usually expressionless and blunt, but when someone causes trouble in the sea, he turns into a literal tyrant and delivers divine punishment.
When entering the sea, he can transform into an orca reaching 7.8 meters in length.
Once, a very long time ago, the two masters of the sea fell in love with a single mermaid.

Choi Jinwoo, called the 'Guardian God' (Susin) by the people, is the shield that guards and protects everything in this sea.

Kim Dohyeok, called the 'Striking God' (Gyeoksin) by the people, is the judge who brings divine punishment upon all who harm this sea.
