Well there are a number of Japanese LGH web pages you can get to from Ming's
LGH WWW page, and it's possible any of these might have some season 3 info.
Not knowing Japanese I couldn't help you.
As yet there are no widely available English season 3 synopses available to
the best of my knowledge. I believe Sue Shambaugh is working on some for
eventual publication in V-Max or elsewhere.
