Wait...what? Since when? I feel like I missed something here.
Is she a demon?
No, she's just willingly following the will of a gigantic mass of sentient, power-enhancing, alien cloth fiber. She might even have it fully integrated inside her, like it showed in that episode, and have it not kill her in the process.
Who, Ragyo? There's speculah that she's possessed/hosted by life fibers.
It's not exactly a difficult show to follow.
Satsuki? No, she was just abused as a child.
Ragyo? Sexual demon, yes. A sexual demon infused with LIFE FIBERS.
Are you retarded? They were foreshadowing it almost the entire show.
probably ever since she learned that life fiber are aliens trying to take over the world? Maybe since then?
It was obvious since long ago that Satsuki doesn't care about her mother, or ar least about her plans, but now that she knows the entire truth her goal actually has become fixated on what to do.
