New, previously non-existent backstories were created, as well as significantly different personalities for the characters. For instance, the unseen father of Nene (known in the dub as "Penny") was suggested to be physically abusive toward both his wife and daughter, and this was used as a source of black humor. Principal Enchou was rewritten as a half-Peruvian, half-Romani man with a complicated prior life that includes a stint as a magician, in which he accidentally injured scores of audience members. Ageo-sensei (known in the dub as "Miss Polly"), Shinnosuke's teacher, was rewritten as a kinky nymphomaniac, while Shin's schoolmate, Kazama, (known in the dub as "Georgie") was portrayed as a hawkish young Republican.
