Ambush!
The Anemone Domain and the Snake Kingdom were eternal rivals.
For a long time ago, the Snake Kingdom was widely recognized as the only overlord of this expanse of water, but this changed following the rapid rise of the Anemone Domain which was helmed by clownfish.
Considering the different physique and combat ability of both species, at a glance, the clownfish seemed to have no chance against their snake opponents, but they turned the tide of the war with technology.
A war of attrition between both races started and lasted for decades with the clownfish constantly on the losing side, this was until the clown god appeared who singlehandedly turned the situation around.
This exceptional clown god was a genius in a lot of ways. Not only did she have fierce combat strength herself, but her outstanding knowledge was also what really turned the situation in favor of the clownfish.
