First of all I'm new here and just joined this Forum. PS the DC in my username stands for Detective Conan not the DC as in movies 
So I just started reading the Manga and am currently reading chapter 77
I watched the Anime a while ago and know that there are actually major differences between the Manga and the anime
Since the Nue hasn't been mentioned (yet) in the Manga I don't think that could be a reason why Sumire is immune
As for Sarada I think her Sharingan/member of the Uchiha clan can be a likely reason why she's not affected. Still I'm not completely sure if that's the only reason for Sarada to be immune against Eida's affection
But for Sumire I have absolutely no clue since Nue or anything else out of the ordinary hasn't been mentioned about Sumire
For me personally only the Manga is canon so I'll only rely on information that was mentioned or will be mentioned in the Manga
Still I'd like to know the answer to my question. How can Sumire be immune to Eida?
Thanks in advance
