I found the older Hunter x Hunter. Would anyone be able to tell me if it's darker than something like Black Butler?
I'm pretty sure it was Black Butler that was too macabre for my liking. I didn't give it much of a chance.
I might have an interest in merfolk, mythology in general, but things have been lost in translation.
I wonder if you'd like the manga titled "Merman in my Tub", even though you aren't as much into the anime these days.
A while ago I lost an online buddy to some furry hypnosis thing I know nothing about. You might want to have some set boundaries in mind before going in too far.
