Hyper Iria

The story begins with Iria as an apprentice to her older brother, Gren, a veteran bounty hunter, and his partner Bob, who work for Ghomvak Security along with a somewhat loutish hunter named Fujikuro. During a rescue mission to a hijacked spaceship called the Karma , they discover that the hijacker is actually a seemingly indestructible alien called Zeiram that broke out of the cargo hold during transit and began to massacre the crew. Bob is critically wounded by Zeiram while evacuating the survivors, and Gren is lost while attempting to kill Zeiram by destroying the Karma . Returning to Myce, Iria finds herself targeted by assassins working for Tedan Tippedai, the corporation that owned the Karma , and discovers a covered-up plot to control Zeiram in order to use it as a weapon.

Iria escapes with the help of Fujikuro and reunites with Bob, who never recovered from his injuries but had his mind downloaded into a computer program. Together they continue to investigate rumours that Zeiram has appeared on Myce, and try to find out what happened to Gren, who also seems to have survived the Karma' s destruction....
