Batticuore. What was once nothing more than one of many european islands turned touristic attractions after their practical use faded over time, with plenty of history and untouched natural scenery... now has been rid of any life form by a mysterious curse. The only survivor? An eccentric fisherwoman that goes by the name of Martha Mahkklen. Not only that! The waters surrounding Batticuore have been repopulated by a new race of creatures, the Trauma Pets! Bloodthirsty animals that have seemingly no other desire than to cause chaos and destruction, which is hardly worth concern for us humans since they're tiny acquatic creatures. While scientists continue to research their bizarre biological makeup and behaviour, the common people have began to use them for sports in all sorts of competitions, both peaceful and violent. Now that's where you step in, not to stop this senseless abuse, but to be the very best at it.
