Basically about this bounty hunter/ gun for higher crew that take on a mission that goes awry when they encounter a nearly immortal alien being and the rest of the episodes are basically this one gal's quest to ( you guessed it) try to destroy it.
They story is nothing special. The mechanical designs and world building are specifically very un-special. It's trying to do cross between woodlands and sci-fi. Think the whole Ewok sequence in Star Wars or a way lesser Tenchi Muyo. The animation has it's moments where it shines with all it's retro charm, specifically the last episode. But I really couldn't get over how boring the weapons and creatures were.
