What is the relationship between Kingyo Sou manga and Manga Rock?

I'm not sure. Maybe they have no direct connection.

It's decent. The adaptation on Manga Rock captures the main elements of the Yuragi-sou manga, but might have some minor differences.

Kingyo Tsuma manga is appealing because of its combination of beautiful illustrations, deep emotional connections between characters, and unexpected twists in the story that keep you on the edge of your seat.

I'm not really sure. Maybe it's got some elements inspired by rock music or culture, but that's just a guess.

I'm not really sure. Maybe 'sou' is related to a specific character or plot point in the 'black bird manga'.

To be honest, I don't have the latest on Yayoi Sou's new manga. But you could search on popular manga platforms or follow relevant social media accounts for the latest news.

There are several manga similar to 'Shibuya Kingyo' like 'Tokyo Ghoul' which shares a dark and mysterious theme.

Not much. Manga Rock was a platform for accessing various manga, but its use might not have been legal for all content, including 'Oreshura'.

Not much. They are likely two separate and distinct manga with no direct connection.

Not much. Kochikame manga is an independent comic series and Manga Rock is just a platform that may offer access to it illegally.
