The original tag pulled from Lofter is ๅฅณๅฑ้ฟ, so it's definitely meant to be the Female Chief. I fixed the tags, but just know for the future that when the Danbooru tags are obviously wrong like they were here, it's okay for you to change them yourself.
Only thing I will say. Stop pretending. We all saw the metadata in your images and thats before everyone else bar you spotted AI from a mile away (because you are lying and we have caught in 4k thanks to the file) :Really:
I made the mistake of replying to someone in that Facebook post to tell them it was AI and now this nutjob has been sending me messages on FB for a week straight.
Characters appear to be Fujimoto Nao and Onodera Ena. Both are female, and much to my disappointment I've seen no explicit indication that they are a couple, either in this picture or in taracod's other work. Tags updated.
- Fujimoto Yui (f) (twin 1) - Fujimoto Nao (f) (twin 2) - Onodera Ena (f) (their friend) - Fujimoto Tatsuhiko (m) (the twins' father) - Either Yoshida (f) (Tatsuhiko's friend) or the twins' mother (f), whose name I don't recall and can't find a source for (they have slightly similar hair and it's hard to ID someone who's that small and half out of frame.)
Characters appear to be Fujimoto Nao (left) and Onodera Ena (right) from taracod's manga, Child. Both are female, so I corrected the tags accordingly. I hope I did it appropriately, this is my first time editing tags here. I don't know when it is appropriate to add / create character tags, so I haven't done so.
