Alright I'll watch the movie somewhere done the line!It's worth watching the movie to simply see a different interpretation of the same story. While RahXephon TV is very much Izubuchi's vision which Kyoda assisted in translating onto screen, I feel the movie is representative of Kyoda's own vision of the same story. But you might not want to watch it right away because most of it is recycled TV footage re-edited in different ways. Might feel boring if you just finished the series.
As for the question..IIRC, Bahbem was a scientist on Mu back when Mulians lived with humans in the same dimensional space. He was involved in some shit that threw Mu into another dimension, possibly due to early RahXephon tuning experiments, and he got stuck in our dimension. He started up a foundation and used his advanced technology as a basis to acquire great power and wealth over the generations, cloning him, all for the purpose of fixing what he sees as his mistake so the dimensions are reunited again and he can go home.
And thanks for that answer, makes sense! If I may ask, what made you personally enjoy the romance so much in the show? (I realize I'm asking so many questions, just want to talk to someone about this show haha).
I feel like the slow build up of Haruka and Ayato's relationship really made it for me. It's not something you see coming and those small plot revelations throughout the series just create such a buildup that it just felt so good when everything came together. I was just rewatching the epilogue when they first meet, whew.
