Bibin is the princess from the Black Planet who attends at the mysterious Black Academy, where she was entrusted by the also mysterious Black Principal to gather "Unhappy Fruits" which are needed for her graduation as a really evil queen. She revives Edward and nicknames him as Edochin, however rather than reviving him with his original form, she revives him with a hybrid between pig and bunny who have the ability of flying, but none of his original powers. Bibin and Edochin frequently causes trouble, however their plans always ends in a failure thanks to Fine and Rein's constant interference.
