Actually not much information about Ragna was revealed. We do know he had a brother, a sister and a screwed up life, but that's it. We didn't know what came before that. But hints that's he's artificial were laid down at some point in the story.

In CS, it was the True End, where he said that he didn't even know whose soul he was having.

In the light novel adaption of CT, Jubei apparently saved Ragna and his siblings from some kind of lab. Of course there are many ways to interpret this, but being artificial is also a possibility.

The mark on his chest is eh... a bit controversial. I can confirm the image came from an official source, but apparently was drawn by a guest artist so it could be BS.

At any rate, let's see if CP will cast some light on this..or not. We all know Mori is a liar and also loves trolling people.
