Shadow Yamoto, ninja assassin from Japan in 1993. Her fighting style was Ninjutsu, a system of unarmed combat similar to jujutsu. This technique is mixed with the art of invisibility. As a member of the Black Orchid Corp, she rose through the ranks, and became a top-notch killer. After successfully carrying out many missions, she questioned her superiors about the consequences of failure. The answer given to her is that she herself would be assassinated. Feeling vulnerable and endangered, she then decided to escape, and reveal the Corp to the public authorities. However, the superiors arranged her death, and had her pushed off the 101st floor of the Corp building, before she could blow the whistle.
