In a dystopian cyber world where violence and crime are rampant, a group of cyborg mercenaries named "Blood Fusion" fight for money and power. They are ruthless and deadly, with three distinct members: the heavily armored and gun-toting "Hulk", the stealthy and lethal female sniper "Shadow", and the crazy and explosive expert "Madman". Blood Fusion is often hired for protection, assassination, or illegal missions, and they always leave a trail of destruction in their wake.
