Kaze was the name used by a male Human terrorist in the 21st century. He styled himself as a modern ninja, though his political beliefs and goals were indeterminate. Kaze was a member of the Easter Rebellion, a small terror cell led by a man named Easter.
In 2045, Kaze took part in an abortive mission to capture a pair of extraterrestrials who had been stranded on Earth. However, their snowmobile broke down in an Antarctic blizzard, and shortly after, he and his colleagues were captured by authorities, and "re-educated" via memory wipe.
