How is the relationship between Manga Rock and Strike the Blood?

I'm not sure there's a direct connection. Maybe it's just a random combination?

Seiheki Strike manga and Manga Rock might have no significant connection. Manga Rock was involved in copyright issues and Seiheki Strike could be an unrelated original creation.

I'm not sure. Maybe there's no direct connection between them.

The Strike the Blood manga and its adaptation have a close connection. The adaptation generally adheres to the main story and key elements of the manga. But, to enhance the visual and narrative experience, there could be tweaks and additions that don't stray too far from the original.

Not much, as Manga Rock was known for hosting unauthorized manga content and Phantom Blood has its own legitimate distribution channels.

Well, 'A Trail of Blood' could just be a manga that was hosted or accessible on Manga Rock. But that doesn't mean they have a specific or unique connection beyond that. Maybe it was popular or frequently viewed on the platform, but that's about it.

I'm not really sure. Maybe there's some thematic connection or inspiration, but I haven't come across any definite link.

Not sure about it. It's possible that Blood Rain could just be a random term and have nothing to do with the Manga Rock platform. Could be a coincidence or something.

I really don't know. It's possible that they are completely separate entities with no overlapping elements or shared aspects.

Not much. Manga Rock was a platform that hosted various manga illegally. Blood Lad manga is an independent creation with its own storyline and fanbase.
