Celine never dyed Rumi's hair
So most people think that Celine is a villain who wanted to change Rumi and make her a perfect little Hunter (exaggeration but you get the gist). If that's true then why didn't Celine dye Rumi's naturally purple hair? It's demon hair. If Celine was trying to erase Rumi's demon heritage then why wouldn't she try to dye Rumi's hair a natural color like black? the only explanation I can think of is that Celine only ever wanted to protect Rumi. If Celine was motivated by hate of demons then logic would deem that Celine would dye Rumi's hair, try to get rid of the patterns and make Rumi hide her patterns. If Celine was motivated by fear then I can see a possibility for the same actions but with a very different heart.
I do believe that Celine really does love Rumi but that Celine was way out of her depth raising a half demon daughter (likely without any family supports) and that she was in a constant state of fear which severely impaired her emotional awareness. What do you guys think?
