|Appears in||Red Faction|
|Voiced by||Ilyssa Fradin|
There is not much known about her and her Mercenary Unit outside of her being the leader and the group having committed many murders for Ultor for at least 15 years. Much of this work included eliminating people participating in strikes and protests. She joined the Merc Corps at 16. Before joining, she spent time in London, and planned to return there to kill the "street scum" that she had bad run-ins with.
She appears to enjoy killing as she murders both Red Faction members as well as Ultor guards and personnel (offscreen) just because she wants to do so.
The First Martian Revolution
After Ultor becomes heavily weakened because of the actions of the Red Faction member called Parker, they call their secret weapon, a ruthless and powerful mercenary unit led by a woman only known as Masako, Her unit is ordered to destroy any evidence that could jeopardize Ultor's control on Mars and so, her unit kills hundreds of Ultor personel and Red Faction members and destroys several Ultor facilities.
After her unit is weakened, she attempts to destroy Ultor's main complex with a large bomb to eliminate any remaining Red Faction members and evidence of previous wrongdoing. In the end, she is killed in a firefight with Parker, who disarms the bomb after her death.
- In Saints Row 2, the private millitary unit working for Ultor is called the Masako Unit, this is clearly a reference to Red Faction as the second enemies the player fights against in the game are Mercenaries under Ultor's paycheck.
- Her weapon of preference is the Precision Rifle.
- Her artwork depicts her as being Asian (possibly Japanese given the name Masako). Strangely, she appears to be Caucasian in-game.
