Years ago, Tatsu Yamashiro was a student training under Master Takahiro in the art of the samurai. She trained alongside Thane Tepes, who had come to train in the art of swordsmanship. The two quickly become friends, and helped each other train, as well as shearing some secrets. Takahiro was also the guardian of a one of a kind 14th century Muramasa katana sword, the Soultaker Sword, a weapon capable of extracting the souls from those that it kills, while also allowing the wielder to communicate with the imprisoned spirit.

At one point, Master Takahiro pitted Yamashiro and Thane against each other. The two were evenly matched, but Thane eventually overpowered Yamashiro with a technique he created himself, trapping her sword in the ground. The Master was actually impressed by the technique. Thane took that as his que to leave, as he had learned all the Master had to teach. Thane and Yamashiro had a tearful separation, but Thane promised that they would see one another again, eventually. Just before Thane left, Yamashiro saw Master Takahiro give a sheeted katana to Thane. She thought it was simply the Master’s way of saying goodbye, and dismissed the event. Sometime later, Yamashiro mistakenly revealed the location of the Soultaker Sword, and a villain named Takeo came to Takahiro's dojo for the sword. She hid while Takeo confronted the master and watched in horror as he was slain. After the villain left, Tatsu quickly ran to her Master, crying. However, Master Takahiro revealed to her that sword the villain took is not the real Soultaker Sword, telling her the real one is hidden in a safe location, and that she would know where to look. The old Master also realized his death was needed to push Tatsu to her peak in order for her to wield the sword.

In honor of Master Takahiro, Yamashiro took a vow of silence. Seeking to be an agent of justice, Tatsu travelled to America as Katana. She also started looking for the sword, as she somehow knew it was near. To pay for her next meal, she has been hiring herself as a mercenary.
