I don't have a clear idea. It might be that the way the story progresses or the world-building is similar. But that's just a guess without knowing more about both.
Some similar manga could be 'Dogs: Bullets & Carnage' and 'Tokyo Ghoul'. They both have elements of dark and intense themes.
I'd suggest 'Attack on Titan'. It shares some similarities in terms of the dark and gritty tone and the struggle for survival, similar to what you might find in 'Killing Morph'. But the monsters and world-building are quite different.
In many manga, killing and stalking are often used as intense plot elements to create suspense and drama. But their portrayal varies depending on the genre and theme of the manga.
In some manga, killing and staking might be elements of a dark or supernatural plot. They could be used to build tension or show the power dynamics between characters.
There might not be a direct relationship. 'Manga Rock' was a platform that hosted various manga, but it's not specifically tied to 'Killing Stalking'.
Killing Stalking is quite distinct. It stands out with its unique plot and style compared to many similar manga.
Well, 'Dogs: Bullets & Carnage' has a similar dark and intense tone. The characters and storylines have that edge that might appeal if you like Killing Stalking.
You could check out 'Parasyte'. It has a similar level of suspense and mystery. The storylines keep you on the edge of your seat, much like 'Killing Stalking'. However, the genres might differ slightly.
Try 'Parasyte'. It has elements of horror and psychological drama that can give you a similar kind of thrill as Killing Stalking. The story is engaging and full of unexpected twists.
Well, I don't think there's a clear relationship. Maybe they are from different authors or publishing houses and have no common elements or storylines.
