Poseidon achieved the throne of the sea god by the faith of the sea and the people of the sea, but the sea spirit beasts did not get what they deserved, especially after the second generation of sea gods became the throne, the great white shark actually experienced the disaster of extermination.

And now. The owner of the sea area of Bikini Bottom, the guest of another world, Yvonne Shadow Song, will lead the sea spirit beasts out of a new path.

The subordinates have three outstanding talents, Spongebob (Borslaino), Patrick (Sakazuki/akainu), and Squidward (Kuzan), known as the three admirals of Bikini Bottom.

(The timeline began before Poseidon became gods.)
