I want to sort the category tags in a way that's easier to find than alphabetical if you don't exactly know what you're looking for. There will be some tags under multiple labels as the tag applies to both labels.
Please give suggestions as to where certain tags should go/new labels that should be made.
The Numerical, X, Y, and Z lists are completely added.
I'm currently going through the A list.

Looking for something different? Try one of these:

It's indeed a good idea to put the categories in in global category or a subgenre.
I would suggest the following:

• Character
• Plot
• Fetish (this is the leftover group)
• Art
• Creature
• Time and space

Off course more off them are also possible, it is indeed a necessity to put the categories in sub maps. This would give a better overview. However, please don't remove any categories, some people won't like it if you remove their fetish.

Even after dead, we raise from the ashes for the sake of manga.
