There was a time when Yoko was pretty low on money and she still had to take care of her younger brother. This made Yoko accept a job offer like no other. The money was good and it seemed like Yoko had the right set of skills for it. What she had to do, is get into an ancient temple/castle, get some kind of a war fan and bring it to the client. They even told the location of the castle. A few people knew, actually, but no one wanted make it official, not before they pocketed the artifact, at least.
So, the client hired a single, armed woman, who can handle a gun and is rough in a fight. They did warn Yoko that someone else might be after the thing as well, they knew it was none other than Lara Croft, but they didn't tell that to Yoko, of course and just hoped that Yoko would take the thing from Lara one way or another. That was also Yoko's intention somewhat, she hoped that a little scare with her rifle would be enough if she was to meet someone there.
At the castle
Yoko was well prepared, she had her whole arsenal with her, as well as a grappling hook to scale some of the walls in case there was no entry. Yet her attire was quite revealing, light and not movement-restrictive. Kind of the usual for Yoko. Anyway, some of the doors were suspiciously open and the ones that werent, Yoko found another way, or climbed over the wall. Eventually, she entered the main building and started looking for a fancy fan. According to some stories, it destroyed the Mongol navy twice... Those were probably the rumors spread by the supersticious people. Regardless, this thing was worth a fortune for some people and Yoko was in need of a fortune.
Yoko heard some faint sounds ahead. Yoko focused her attention to that direction and made her way there sneaky beaky-like. Yoko peeked through the door and saw an athletic woman opening some old chest/box.
Hold it! Before Lara could take the thing for herself, Yoko would shout out as she entered the room and pointed her rifle at the archeologist.
Turn around and walk away. Slowly! Yoko would threaten as she would take a good look at the woman - there was no mistaking it, it was the famous Lara Croft, no wonder she got here first...
The client told Yoko that others that were looking for the artifact were doing this for the thrill of it, as a hobby. The client then followed with a justifying speech about keeping such an item safe and not letting it get into the ''wrong hands''. Long story short, regardless whether it was all bullshit or not, it made Yoko believe that she was doing the right thing and she was not letting Lara walk away with it.
Never thought I'd meet the great Lara Croft herself, it's an honor, i must say...
