Sundown is the screen name of the Kindjal's pilot, a very cute Russian
girl named Tamiyka Borodinya whose piloting skills are best described
as "pretty good" - about average for PCs, in other words. Her skill at
programming isn't anything special, her weapons are basically making a
basic weapon system way overpowered and cramming it in wherever it'll
fit. The exception to this is the Psycho Kick, which was written for
her by a friend after witnessing Tamiyka on a **SUGARBUZZ*** dealing
with a Senior who tried to get fresh with her. 

She's on a again-on, again-off relation with Mike "Mustard", never lasting 
a full week with or without him. Also, she's the "best of enemies" of Alexei,
her fellow Russian pilot, to whom she kepts those insults she don't
venture to throw to Mustard each time they broke and those nasty new
martial arts kicks she codes on her mecha, but each time someone
interferes betwen their fights, both of them work as the Temible Team
untill the interloper is no more (verbally or virtually speaking -by now...)

Note: "Kindjal" is the name of a kind of sword used by the Cossacks, a
military subculture of czarist Russia that formed the basis and origins
for a number of the mythic heroes of Slavic storytelling. Kind of like
the Light Brigade in Europe.

As of Game Start Time, Tamiyka has only really known about VM for
a month or three, having been introduced to it by Mustard on one
of their early dates. For the first month and a half or so, she
just played in Arcade Mode, with the stock VMs, and got to the
point where she wasn't half bad and decided to play Campainge Mode,
buying a copy of her fave stock unit to start with. Naturally,
being a stock mecha, it was barely able to keep up with the many
custom jobs of Campaign Mode competition. This was good for her
piloting skill, forcing her to improve relatively rapidly, but
frustrating, so she started learning VMPL coding with Mustard, and
working on Kindjal, which is about 3/4 done as of Game Start Time.
It so happened that just a day or two before Game Start, she
entered a game in the Domino Death arena that IYS (Who is just one
of the people in the crowd at the arcade, basically) had also
entered, as the last time he'd play with the Mad Cow before
switching to his brand new unit, just finished, and which he
promised to give a copy of to whoever killed him and/or won the
game, whichever came first. Tamy shot away the last bit of support
on a Tall skyscraper and knocked it over on top of him... splat!
True to his word, IYS had the game attendant copy his code onto
the blank portion of Tamy's VM cartridge, and now appears at the
arcade in a somewhat similar unit with a buldozer motif instead
of bovine. Tamy considers the avatar ridiculous (Though Mike
loves it, naturally) but as it's tougher, faster, and hits harder
than her previous, stock unit and does have a certain unique
style to it, she pilots it anyway, until Kindjal is finished and
debugged at least.
