According to the twitter of Itosugi Masahiro, the first and the third volumes of manga Aki-Sora will be discontinued this July. Itosugi said those volumes have been censored due to the descriptions of incest. He stressed that obscenity was not the reason for the censorship.

He said it's a great loss for the manga culture that one of the motifs has been banned as a result of the Tokyo's ordinance.
