I'm glad you like them :) I usually make them as I read the chapters so its not too hard. I have trouble remembering all the characters, especially with none English names, so I got into the habit of doing this and am happy to share.
I have them all linked in my signature on all my NUF posts. If you click the "information" tab on my profile you can see them also. They are in a spoiler box labeled "Relationship Diagrams I made"
