It's got ... fanboyism. Just about every story contrives to get at least one central character naked. It takes just about every single element of Touhou canon and runs the other way with it (to start with, nobody can fly in UD's Gensokyo except "the most powerful beings," and everyone speaks English), to the point that you might wonder why he didn't just make an original setting. But the important thing is, they are very well written.
