She got into music at a young age when Stewart, her father, wasn't training her in the arts of the Chrono Ninja.
After Trevon was born, Stewart died during a mission and she left for Cyberdyne to follow her dreams and then she got arrested for a crime she didn't commit and became a Penitatas and was only given one cycle before the courts freed her looking 18, but is in her 30s. Trevon is in his 20s, but looks 3 (Perma Status Penitatas).
Like other rabbits, she is obsessed with her ass (I guess because the word "bun" is in the word bunny or something.)
