What is the reason behind this strange censorship of a specific scene in Tokyo Ghoul? During the scene where Kurona and Nashiro are fighting Juzo in Season 2 Episode 4, I noticed some censorship. Juzo ends up stabbing Kurona a lot with his knives, but it's blurred out like this:

I thought this was really strange seeing as the series has shown far worse, such as torture and other extremely gory deaths. Is there a particular reason for this?

The main reason is Japanese censorship laws, which are very different from laws in the West, but some people have mentioned that S2 was airing at the same time as some ISIS attacks took place, thus this might have something to do with TV networks censoring knives.
