But I might suggest that Yukino and Angel may be sisters. Yukino said that Zeref followers attacked their village and her sister was taken from her. The only plausible Zeref followers are: Grimoire Heart, Tatarus, and the Tower of Heaven. Now, most of the slaves are children which implies that they were also taken from their homes as well. Another suggestion would be Sorano's appearance. White hair like Yukino, Might be wearing a bow, Has some obvious bangs. If I didn't know better, I'd say that's the exact look of Angel during the Oracion Seis arc. Just saying, kay.
