This kind of incest will never happen... again.
According to Ito Masaki's official blog, one of the members of Tokyo Metropolitan Assembly, the ruling party, the Democratic Party of Japan has decided to approve the Anime and Manga Regulation Bill.
The other two major parties have already approved the bill, so it will pass the assembly on December 15. DPJ agreed with the bill on condition that the resolution will be made with a collateral claim for a careful operation of the regulation. However, the collateral claim is not legally binding. The regulation will be enforced on July 1, 2011.
Manga-ka, Takaku Shoko tweeted that one of the major publishers turned her manga down because one of the characters in a high school uniform could contravene the local ordinance of Tokyo. She was frightened to know that the bill has already made the industry flinch.
Manga-ka, Meiji Kanako tweeted that the re-release of one of her manga has been under deliberation because of the descriptions of minors' sex in the manga. She said she won't be surprised if it's canceled.

I smell that Shonen Jump will not be anymore called Shonen Jump but more like, Seinen Jump due to this Bill!
