Hailing from San Francisco, Cierra's personal history has been unremarkably blank, until she picked up a spanner from a local chop shop that raised her as one of their own. The shop allowed her to get exposure to her passions as a car mechanic, also earning said staff as a family to lean towards. Slowly but surely, she would earn a reputation modifying cars to be street race ready in a short period of time. Over time, she gains an understanding on what to do if a car needs to drift, grip, drag, or just even lay low on the pavement with lamps all around.

While her social skills remain an all time low due to her timid soul, her ever growing skills in developing and maintaining top levels of performance at a young age manages her to receive scholarships for special tutoring from various manufacturers around the world. From experimental American machines, European supercars, to the domestic powerhouse in Toyota, there's very little in the car she doesn't understand.

Cierra also received the lovely perk of testing out cars from the chop shop just as soon as she reached her sweet sixteens. This skill would work out well for police evasion and warrant issues she piled up. It's unknown how she manages her way in and out of San Francisco with a warrant for her constantly present in the California area alone, but sightings of her in Toyoda would be the last anyone's heard of her in the public.

Her latest caper has her ousted from her home turf, and somehow end up in London, where she becomes another of the Chosen: The Messiah's chosen racers for him to mentor.
