According to the twitter of animator Arai Jun (the key animator of “Star Driver: Kagayaki no Takuto”), episode 2 of Persona 4 The Animation was leaked to video sharing sites with French subtitles before the TV airing in Japan. The OP sequence of the anime was also leaked yesterday prematurely. Arai Jun disclosed that the production studio AIC A.S.T.A. has been swindling the animators and his salary hasn’t been paid even after the deadline. Animator Murata Toshiharu (the character designer of “Hellsing”) agreed with Arai that there is something wrong with AIC studios. Two anonymous animators (@zouni and @bito) also tweeted that they quit the team of Persona 4 from episode 3 because of AIC’s bad management.
