Bonus concept obake

Keiko "Obake" Uzami is the right-hand to Slick Clyde (she's also his foster daughter) in the video game Vigilate 8: 2nd Offense.  She is a ninja who drives a futuristic motorcycle called the Tsunami.  Her special weapon accelerates the Tsunami to the speed of light, causing it to slice through other cars like a hot knife through butter.

In the end, after she learns that Clyde killed her biological father, she overthrows him and takes over OMAR, turning it into a much more environmentally-friendly company.
