1. If the corpse appears too bloody (such as the headless one on the roller coaster in Volume 1), mosaic will be used.

2. It should be a printing problem and a cutting problem. This may happen if you buy a whole set of books. (I'm not sure why ...) You should be able to make a complaint or return it.

3. I don't think so, but there will be a certificate of authorization on the penultimate page at the back of the book.

4. It's normal, so is mine ...

I hope you are satisfied.
