Just like the relationship between Tokyo Ghoul and Kiseijuu, Shiki and Kiseijuu are similar in almost the exact same way. It's essentially a transition from humanoid creatures to very much alien creatures. Still, I think it's worth watching them both. Just as a warning, Shiki is technically a part of the horror genre. It's not gory at all, but the atmospherical tension is intense.

They both have very similar messages, just that it's easier to sympathize with ghouls opposed to parasites. Both bring up questions people, in general, dislike bringing up and both have fairly philosophical aspects. They also both have main characters who eventually become stronger. I'd say more but I won't spoil anything lol

Shiki is very similar to Tokyo Ghoul although Shiki is, arguably, darker. They both have a humanoid creature that has many similarities to humans and there are various conflicts between the two species. However, Natsuno(From Shiki) is not really a weak character from the beginning like Kaneki(Tokyo Ghoul) I'd recommend watching Tokyo Ghoul and Shiki before Kiseijuu. I think it'll make watching Kiseijuu much more interesting.
