User blog:OOQuietSnowOo/Help with removing categories?

Sooo... I usually type pretty fast & it happens sometimes that I spell a word incorrectly. Well, most of the times. While I was editing an image gallery for Haruka Nanase and adding images to categories, I accidentaly spelled some words wrong & therefore created new categories that I didn't want to.

I don't know how to remove them. //gets shot//

Can anyone help me? These are the categories that have to be deleted: Images_of_makoto_Tachibana, Imakes_of_Nagisa_Hazuki, Images_of_haruka_Nanase

Thanks,

Jeka~ :)
