These are concepts the author has made recently and also talked about on her blog. Check out her post, will ya?
To quote her post, "After finishing the animation and looking at the final results, it made me think: What if SaGia had a full on animated pilot. I could bring back some of the voice actors from the Volume 2 second trailer that I shared last year. It would have that 80s/90s cel-shaded look" and "If you want to see a SaGia animated pilot happen, email me, leave it in the comments, beg me, annoy me. It it gets enough support, I'll try to make it happen and do the best I can with it since I'm working on a low budget and as I said, I don't have great animation skills".
To the SaGia fans and non-SaGia fans out there, if you want to make this happen for real, let her know. She hasn't been doing great recently and updates on the comic itself are slow due to the low readerbase. We don't want to see SaGia end on a cliffhanger, right?
