Who is the kamek-glasses weirdo with the blue and yellow polka dot shirt?

I love watching old episodes of Gegege No Kitaro. Especially the ones with Nurarihyon in them.

Now I did notice that most of the episodes listed on here don't have a synopsis, or a wiki article at all...

That's not good. How will anyone know what the episode is about?

So I got to say... I'm preeeeetty tempted to watch all the episodes I can find that have translated subs, and write a short synopsis for them on here...

The 1996 series will be the hardest episodes to find for me. It has like over 100 eps and I can only find 10 of them...

Any help would be much appreciated!
