Soul Stone

Life is strange and normally short, but for a select few life is as close to eternal as they could of hoped. How could this be? A deal with a goddess and a few mysterious stones is how. Two people make a deal with a goddess for eternal life. In exchange for the life expanding stones they had to provide entertainment for her for all eternity. How could they do that? With an endless game of slaughter, one that caught several hundred planets in its path. This game was meant to last till the end of everything, but that's not how it's played out.
The game was interrupted. A stone stolen, soul trapped within it, the body being used by a new spirit. That's how Kirara came into existence. She enjoyed having an average life, having a family; even though some members are beyond annoying.
But nothing stops forever. The stone is returned to the body, her normal life gone, replaced with an obsessed madman, an unsuccessful team, and a love just out of her reach.
