I took the liberty to organize the categories of the wiki. I used the navigation pages in the homepage as a reference to what it is supposed to go in Category:Content and then I took a top-down approach at categorization, e.g. if Category:Characters is a top level category, then Male Characters must be a sub-category, and so on. I had to create some pages over the categories to add the subcategories but I linked the main articles in each. I also marked some redundant categories (like Category:Manga) for possible deletion.
The Category:Cyclist_types sub-categories could benefit of having all the content in the main article and making the main articles redundant.
