History[]

Early Life[]

Shiho Yamamoto was born to a single mother. After faking her death in a fire, that took the life of her mother, she got in touch with her father, Jairo Yamaguchi, the Oyabun of the Yakuza. Although at first Mamushi tries to pretend to be a loving daughter, she ends her act, when her father disregards the possibility of her taking over Yakuza.

In order to impress her father and show him, that Mamushi can become a great leader, she overhauls every single business unit from gambling to prostitution, turning them massive cash waterfalls. Still, this doesn't please her father and Mamushi decides to kill him and take the leadership of Yakuza by force.

After killing her father and taking control over Yakuza, she consolidated her power by marrying his top lieutenant, Hiro Mori. This helped to keep the police, the press and the gangs off her back. Nine months later, she conceives a daughter, Kazuko with her husband Hiro. Sometime later, she kills Hiro and completely takes over Yakuza.

The Collision[]

During the Collision, Mamushi leadership was tested by various smaller gangs, who wanted to take Yakuza from her hands. Thus she waged war with any opposition, she came across. Mamushi also started selling Shade all around Onishima. She was then approached by Mezu, who proposed a business arrangement. If Mamushi lets Mezu to conceive a child with her daughter Kazuko, he will give her enough power to destroy all opposition.

Although hesitant at first, Mamushi accepts Mezu's offer and lets him to violate his daughter. This leads to Kazuko giving birth to a crossbreed daughter, Kamiko. Meanwhile Kazuko herself dies due birth complications. Mamushi is at first enraged by this outcome, but in the end accepts it. When Kamiko shows interest in working at Zilla Labs, Mamushi is completely against this idea, not wanting to deal with Zilla. But when Kamiko suggests, that she could spy for Yakuza and let them take over Zilla Enterprises from the inside, Mamushi complies as Mezu begins showing lots of interest in Zilla's experiments. As per their agreement, Kamiko starts sending regular reports on Zilla's research.

Shadow Warrior 2[]

Mamushi hires Lo Wang to retrieve a trinket from a Temple of Longing. Soon after hiring him, she calls Lo Wang to check if he completed the task. Lo Wang tells her, that they agreed, he will deliver the relic until 5:30 and it's not even 4. Mamushi reiterates, that Wang was specifically chosen for this task as the temple and its surroundings are occupied by demons. Wang disregards these warnings. Once he retrieves the relic, he returns it to Mamushi at her mansion. At the mansion, Mamushi together with Smith Masamune meets up with Lo Wang. Wang is surprised to see Smith working for the Yakuza, but Masamune corrects him, that he's here on a personal matter and doesn't work for Mamushi.

Mamushi informs him, that Kamiko, the daughter of Yakuza's leader, has disappeared. They believe, that Zilla had something to do with this, as she was spying on him for Mamushi. Mamushi plans to send a rescue party, but Wang volunteers to go alone, if he's payed enough. He believes, that alone and with his knowledge about Zilla, he has a bigger chance to rescue Kamiko. Mamushi agrees, but tells Wang to bring Kamiko to Smith's garage as the mansion will be the first place Zilla will look for her. Before leaving, Smith takes the retrieved relic off Lo Wang hands, saying that he will give it to Kamiko, once he sees her.

After Wang rescues Kamiko, Mamushi contacts him, asking if her condition has improved. He tells her, that they still working on it. She then insists, that Lo Wang would meet her in her office located in the abandoned laundry on Dragon Mountain. Mamushi orders Lo Wang to retrieve Kamiko's secret research she has been working on. She believes, that Kamiko wasn't sending all the information to her and kept key notes in her apartment in Zilla City. Wang is at first, hesitant to take up this task, but Mamushi reminds him, that because he brought Kamiko "broken", he belongs to her. She also warns Lo Wang, that Zilla 's forces will be guarding the apartment building. Lo Wang succeeds with his mission and retrieves Kamiko's notes for Mamushi, but unbeknownst to her, they're fakes.

Later, Mamushi gives Lo Wang a task to shutdown a Shade cookery in the slums. This will send a message, that no one should cross Mamushi. Unfortunately, the man behind the operation mutates into a Talon, leaving Wang no other choice, but to kill him. Mamushi isn't too trilled about this news, as she wanted the man to be on her payroll.

Soon after, Mamushi orders Lo Wang to find the source of the black ooze that's permeating the wildlands. She believes, that is coming from one particular place and gives Wang the coordinates to it. After ZillaCorps attacks the Dragon Mountain, she relocates back to her Yakuza mansion. While in search of Oyabun's dagger, Wang attacks the mansion. As he battles through Mamushi's personal army, she hides in her underground panic room. Lo Wang uses dynamite to blow open the door, blocking the entrance to the room. Inside, he confronts Mamushi about her decision to sell her own daughter to Mezu in exchange for power. Mamushi tells Wang, that she always knew the price of her bargain and doesn't regret her decisions. She then proceeds to stab herself in the abdomen with the dagger, slowly bleeding to death.
