I dont recall the names, i was looking for Seikai amv on animemusicvideos.net and saw a lunar one and wanted to find out where the footage came from.

Ive been watching some AMVs that have video from lunar in them, which made me think that there must have been an animated series at some point. Are these videos just cutscens? Or is there somthing more?
