I thought you were messing with me, but it seems like an actual cartoon!
Is it worth checking? Plot driven or character driven?
I would describe Lord of Mysteries as a "Dark Harry Potter" series. I'd say it focuses on
world-building and
action/suspense with
gore elements to it. The English voice acting is befitting the Victorian-era in which it takes place (you don't feel like you're listening to a Dub). But I must admit I had to check a youtube video to explain episode 1 for me because you get introduced to a bunch of concepts.
As for Link Click, it is
character driven and has a more
detective and
emotional element to it. It's essentially about the main characters being given photos by different clients. These photos allow the main characters to "re-live" the past captured by it through a person in that photo. They do this for different purposes requested by the client. There are some rules they need to abide by when doing so.
If you wanna pick one, and give it only 1 episode to decide whether to continue watching, then I'd choose Link Click.
