City Streets is primarily two things, in terms of genre: fantasy and boy's love (also known as shounen-ai - refers to stories depicting male homosexual relationships.) There will be elements of shoujo-ai (lesbian relationships), although this will not be the focus of the story.

Romance won't play a big part in the story until later on. The storyline of the first arc is mainly action.

This comic probably isn't suitable for those under the age of fifteen, given that there will be a fair amount of violence, blood, and some bad language.
