If there's any kind of comp or good use for Enma, I don't see it. His only use is as a wall, he doesn't have any chases. I wouldn't suggest using him until you have a strong three.

Also the only couple times I used him, he died way too quickly to be useful.

I believe, comparing Guarding to Kankuro's puppet, that it is supposed to just draw Enemy attacks. Much like Hinata or Neji. I'm not a hundred percent on that though.
