You want to write a chapter about hair in your new book so you have to make sure it's really clear. Clear enough so that ANYbody can read it.
It's so clear and concise you decide to patent it. Now it's yours and yours alone.
Your clear writing got the attention of the Shougun (しょう) and now he's at your door once again, but this time he's angrier than usual. Apparently he was going to steal your clear explanations but since you've patented it, he can't.
