What is your opinion on Angela/Ash?

I personally think their characters were very… Useless. In my opinion, if they were actually canonical to the manga I would've been at least five times more interested in the characters. But nope! The only purpose of them being created was to re-traumatize Ciel and purify him and basically show an exaggerated form of religious trauma (which does happen). Whoever decided to botch the last fifteen episodes of season 1 needs a serious talking to...it was interesting but literally what purpose was it for if she doesn't actually exist?????
