In the midst of Mecha Sally's assault on the Freedom Fighters, the princess turned weapon destroyed what it believed to be a fully roboticized Bunnie Rabbot, but was merely a robotic mannequin of sorts; the incident witnessed by the real Bunnie Rabbot herself, now fully restored to flesh and blood. After barely surviving the deaths of some her closest friends, including her husband Antoine, she finds herself devastated and alone...
With her old life suddenly gone, she soon finds a new home and warm welcome in the form of The Rabbit family. A chance to start over anew, she comfortably settles in with her new family, and soon begins learning a uniquely useful skill from her new 'sister'.
