Crunchyroll will be streaming Kiseijuu (Parasyte) simultaneously with its release in Japan (some delay due to subtitling reasons, of course). Check out below the full list of regions where the show will be available via the online service.
USA, Canada, South Africa, Australia, New Zealand, Latin America (Central and South America), Europe, Middle East, and North Africa.
The show will have 24 episodes. If you recall, Crunchyroll streamed Akame Ga Kill without any additional censorship. Judging by the uncensored preview on Crunchyroll, I can say that there is a high probability that Kiseijuu show will be uncensored as well.
