OOOO I get it....
He's Gi-Go because hes the fifth prototype and your attempting to over use Japan in your animation........ I see, but why the "Gi" cause it doesn't sound like human, alien, or DNA soooooo....... no se. I'm impressed with your drawing style and your animation but I don't love your story or the way you carry the violence or your resoning for 1. His mouth being closed. 2. He's killing people... after he resolved that he was done and no one desserved to die by his hand. 3. Why does he wanna go to "paradise", did he just figure, hey I'm done with this, or something?
Sorry and I hope your not taking this offensively because I mean none and you'll be better than me at this forever so..... congrats,
P.S. You spelled access wrong in episode 1.
