Mayumi was born in Japan and had a typical early life. When she got older she fell in love with a “bad boy,” who introduced her to drinking alcohol when she was 17. She began using alkyl nitrites and marijuana, and as she moved on to harder men, she moved on to harder drugs.

A later man got her hooked on methamphetamines, and to raise money to support her habit she began to prostitute herself. When she could not raise enough money on her own, she became the “property” of a pimp. Later, she was sold overseas into the United States. Her exotic looks were prized by her new owner, but her meth habit greatly reduced her usefulness as a prostitute.

Eventually, she was purchased by a doctor, who proceeded to break her habit and clean her up. The doctor, though, had a reason for buying Mayumi. A psychopathic man had crippled the doctor, and raped and murdered his wife. And so, the doctor planned to train Mayumi to be the instrument of his revenge.

He trained her in the martial arts, and in the use of firearms; in how to kill and how to withstand pain. Eventually, he gave Mayumi a drug that would make her appear dead, surgically inserted a broken down handgun into her body, and smuggled her into a compound where she could find her target. After awakening, she dispatched a guard, broke open the sutures, reassembled the gun, and killed everyone in the compound, including her intended target.

Now that she has completed her set task, she has determined to track down everyone who did wrong to her in the past...and kill them.

Death Battle Info


Mayumi is an attractive-looking Japanese woman of about 29 years of age, but not unusually so. Her appearance will not draw attention to her. Even her name is a common name for females in Japan, perhaps equivalent to Jane in the United States.


This young woman is heavily trained in the martial arts and in the use of firearms. She was also taught to not be afraid of having bullets fired at her, to resist pain and to carry on in spite of blood loss.


  • Glock 17 – Mayumi was last seen using this weapon. It is a semi-automatic pistol that fires 9mm Luger ammunition, and has an 18-round magazine.
  • Heckler & Koch USP Compact – This was the disassembled firearm that was inserted into Mayumi’s torso. It is a semi-automatic pistol that fires 9mm Luger ammunition, and has a 13-round magazine.


While finishing her hunting and killing of Hamazaki's son, Mayumi suffered the equivalent of at least a class III hemorrhage, yet kept her consciousness and focus, and got herself to her extraction point, where a transfusion was given to her.
