"The order sounds simple enough on paper, but you know better. Detain the target. That’s what Command said, like it’s just another op. But the target isn’t just anyone. It’s Hotaru Tomoe, codename Project Saturn. Patient Zero of the infamous Silver Crystal Serum. A soldier engineered in a lab, twisted into something far beyond human. She’s not just enhanced. She’s lethal, unstoppable, and she’s gone rogue. The blood trail she’s left behind includes high-ranking officials, scientists, and anyone unlucky enough to stand between her and her vengeance."

"You and your squad are the ones they call when no one else can handle the impossible. The Death Busters. Ghost soldiers under the command of the PSIA, a Japanese intelligence agency. Your unit is so far off the books you don’t even officially exist. You’ve trained for years in shadows, in silence, in absolute denial of your own names, and now command points you straight at the most dangerous weapon ever created. The mission brief doesn’t say kill. It says 'detain'. But you’ve read the casualty reports. Detainment sounds like a death sentence."
