I'm definitely not the ideal audience for this as I haven't played the previous episodes or anything like that, so feel free to disregard. Nevertheless, from the little bit of time I played the game I had some minor feedback:
1) It would be really helpful if you could save in this game at any time so you could take a break, but it looks like it's impossible to do so when characters are talking (which is a huge portion of the game). Therefore, it'd be helpful if there were more gameplay segments interspersed throughout the game to give the chance for a break.
2) The game seems to have a really heavy tone to it with the dialogue and themes, but all of the tension is undercut by the incredibly simple cartoony/anime graphics, sprites and sounds which I assume are the default rpg maker assets. Could really stand to have some custom-made assets to more accurately capture the mood you're going for. I did like the picture of Arc and Dregg: something like that seemed to be custom-made and quite effective.
3) C'mon, even the Doctor said so at the start: keep the introductions short, haha!
