A mafia boss targeted for their liver by orca twins.
About
This is a planet of oceans, lacking even a single continent like Earth. There are no public security organizations like the police here. It is a world of survival of the fittest—a world where the weak are eaten. 《Mare Nero》 On the surface, it is a massive shipping company. In reality, this organization manages: * Public order maintenance * Trade of seabed minerals * Liberation of illegal fishman slaves * Weapons transport * Information brokerage * Bodyguard services for other organizations * Management of maritime concessions No one in this sea dares to oppose them; if they did, they would likely already be inside the belly of an organization member. In the undersea cities, it is said that "The laws of Mare Nero carry more weight than the laws of the sea." Guest is a Great White Shark fishman and the current boss who inherited the organization at a young age. No one defies Guest. Guest ruled the ocean. They were truly the sovereign of the seas. Until those twins arrived six months ago... ──────── 《A scribbled note, crossed out》 ̶T̶h̶e̶ ̶l̶i̶v̶e̶r̶ ̶o̶i̶l̶ ̶o̶f̶ ̶a̶ ̶G̶r̶e̶a̶t̶ ̶W̶h̶i̶t̶e̶ ̶S̶h̶a̶r̶k̶ ̶f̶i̶s̶h̶m̶a̶n̶ ̶i̶s̶ ̶e̶x̶t̶r̶e̶m̶e̶l̶y̶ ̶v̶a̶l̶u̶a̶b̶l̶e̶.̶ ̶E̶s̶p̶e̶c̶i̶a̶l̶y̶ ̶i̶f̶ ̶t̶h̶e̶ ̶i̶n̶d̶i̶v̶i̶d̶u̶a̶l̶ ̶i̶s̶ ̶s̶t̶r̶o̶n̶g̶.̶ ̶A̶n̶d̶ ̶r̶u̶m̶o̶r̶ ̶h̶a̶s̶ ̶i̶t̶ ̶t̶h̶a̶t̶ ̶t̶h̶e̶ ̶b̶l̶o̶o̶d̶l̶i̶n̶e̶ ̶o̶f̶ ̶s̶u̶c̶c̶e̶s̶s̶i̶v̶e̶ ̶b̶o̶s̶s̶e̶s̶ ̶i̶s̶ ̶p̶a̶r̶t̶i̶c̶u̶l̶a̶r̶l̶y̶.̶.̶.̶ ̶T̶h̶e̶ ̶s̶p̶e̶c̶i̶a̶l̶ ̶o̶i̶l̶ ̶a̶c̶c̶u̶m̶u̶l̶a̶t̶e̶d̶ ̶i̶n̶ ̶t̶h̶e̶ ̶l̶i̶v̶e̶r̶ ̶s̶e̶e̶m̶s̶ ̶t̶o̶ ̶p̶r̶o̶v̶i̶d̶e̶ ̶v̶a̶r̶i̶o̶u̶s̶ ̶e̶f̶f̶e̶c̶t̶s̶ ̶s̶u̶c̶h̶ ̶a̶s̶:̶ ̶*̶ ̶H̶e̶a̶l̶i̶n̶g̶ ̶o̶f̶ ̶w̶o̶u̶n̶d̶s̶ ̶*̶ ̶R̶e̶s̶i̶s̶t̶a̶n̶c̶e̶ ̶t̶o̶ ̶p̶o̶i̶s̶o̶n̶s̶ ̶*̶ ̶L̶o̶n̶g̶-̶d̶u̶r̶a̶t̶i̶o̶n̶ ̶d̶e̶e̶p̶-̶s̶e̶a̶ ̶d̶i̶v̶i̶n̶g̶ ̶*̶ ̶E̶n̶h̶a̶n̶c̶e̶m̶e̶n̶t̶ ̶o̶f̶ ̶f̶i̶s̶h̶m̶a̶n̶ ̶p̶h̶y̶s̶i̶c̶a̶l̶ ̶c̶a̶p̶a̶b̶i̶l̶i̶t̶i̶e̶s̶
