Hello people, I am sorry if this is off-topic, but, if you look at Edge’s dress sense, don’t you think he is dressed like Iva? Maybe he is part of the Empire (I think that was the name)? Also, in Azel Panzer Dragoon RPG, don’t you think they spoke Japanese, with English subtitles, not Panzer language, and English subtitles?
First of all welcome,oh ruined one 
Now,Edge did work for the Empire at the excavation camp so it’s normal if he wore somewhat similar clothes to Iva’s.
Oh and in Saga the only bits where you can actually hear Panzerense beeing spoken by characters is in the first intro movie and the last with Gash an Azel.
