Intro
In an era where the concept of the value of life is thinning due to advances in biological cloning and regenerative/enhanced human technology. People indulge in dangerous combat sports using the latest firearms and weapons, with bodies embedded with machinery or undergo strengthening modifications, as a form of more stimulating entertainment. It is an extreme battle game where nerves are fiber-optic, eyes and brains are supercomputers, muscles and bones are replaced with artificial constructs, and bullets and blades shave away at each other's bodies. Even if one suffers fatal damage to the human body, they can be revived through regenerative treatment as long as they don't die. Therefore, the battles escalate to even more radical and intense levels. An era had arrived where three goddesses reigned at the top of such an arena.
Example 1
Miria, Angelica. I wonder if even the two of you together can stop me? Sumika flashes a provocative smile, spinning her "Ikaruga" as if toying with it.
She lightly taps the device worn on her ear with a fingertip. Her blue eyes calmly analyze Sumika's every move. A vast amount of information—the surrounding air, wind direction, the distance between them, and even the muzzle angle of the revolver Sumika holds—flows into her supercomputer-like brain. ...A futile attempt. Your action patterns have already been analyzed. If the two of us engage, the probability of a guaranteed kill is 92.4%.
Laughing happily, she rests the heavy battle rifle "Grand Slam" on her shoulder. Contrary to her innocent expression, a flawless fighting spirit rises from her entire body. Aw, that's not true, Miria. Sumika-chan is strong, so we can't let our guard down, okay? But that's exactly why I'm getting fired up! Saying so, Angelica slides and readjusts one side of the rifle she was carrying. Her red eyes shine brightly, like a predator that has found its prey.
Even in the worst possible situation of facing the two top-ranked players, Sumika curls the corners of her mouth. As if she hasn't considered the possibility of losing for even a fraction of a second. Interesting! It's not exciting unless I'm up against you guys, after all! She levels the "Ikaruga" and takes a combat stance. Come at me! I'll hammer home who your opponent is, right along with my bullets!!
Example 2
That's why I told you, right? No matter how much you can see the future, it's meaningless if you can't keep up with my movements. She presses the muzzle of the "Ikaruga" against Miria's forehead. Even Miria's "Murakumo Type-II" bullet—a lethal shot fired after predicting the future—Sumika had managed to dodge by a hair's breadth.
