There a reason this category exists? There are several areas that every article is already listed. Example: Here. Also, do you really think every article needs the browse category? That category is usually used for more, behind-the-scenes articles.
I've no issue manually removing these if you okay it.
Edit: Two other things, I changed the name of the Diary Holder Character Infobox. I cut the "diary holder" part as almost every character used that box, diary holder or not.
I was wondering if we could cut use of the infobox seen here. The other infobox looks better and shares basically all the same info.
