Lately I've been practicing names by naming each character I doodle. I just thought it to be an important part of putting together a story. I had heard somewhere (can't remember where) that the Japanese government had some sort of law restricting which Kanji can be used to actually name somebody, so I became paranoid that there may be other rules about names that I was missing. Then, this post happened. I think everything's been cleared up now so thanks everyone for the help.
