What's the relationship between Sakura Trick manga and Manga Rock?

Not much. Sakura Diaries manga is an independent work and Manga Rock was just a platform that might have hosted it illegally.

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

There's probably no significant relation. Manga Rock's reputation for unlicensed content makes it unlikely to have a legitimate tie-up with 'Sakura Taisen Kanadegumi'.

Well, Chobits manga is a separate creation and Manga Rock is a place where you might find it available. But they aren't inherently related in terms of creation or content.

The connection between Hinamatsuri manga and Manga Rock could be that Manga Rock was one of the places where you could find and read Hinamatsuri manga. However, be cautious as using some unauthorized platforms for manga reading might not be legal.

Not much, really. Yotsubato manga is an independent work and Manga Rock is just a platform where you might find it.

I'm not sure exactly, but Manga Rock was known for hosting unauthorized manga, including Inuyasha, which is illegal and against copyright laws.

Not much. Kuromukuro manga is an independent creation and Manga Rock is just a platform that might host it.

I think there isn't a direct connection. Manga Rock was known for hosting unauthorized manga, and 'Hiyokoi' manga may not have been officially associated with it.

I'm not sure. Maybe there's no direct connection. Don't know much about it.
