This seems to be one of the artist's OCs rather than an Arknights character. At the very least, none of the other posts with this girl are tagged with that copyright.
Add her to the list of Hoyo Characters that need a hug (which includes Scara, Kiana, Firefly, and many, MANY others). Because she looks like she REALLY needs one. That’s the look of someone who’s trying to hide the fact that they’re DEAD inside.
Considering the rest of the barrel has steam or smoke (artistic representation thereof at least) she likely burned herself on it. She probably touched the silencer on the end after tearing through several mags at the range, the silencer and the barrel would be very hot after half a dozen mag dumps, especially with the silencer trapping so much heat by its very nature.
Judging by post #6722451, the girl on the left is Haruka and Sora's daughter. Not sure if that's enough to justify the mother_and_daughter tag though.
Yes, it is enough. Though it might be a good idea to make a tag specifically for non-canon children. We do have if they mated, but I don't think it would apply here since we can't tell from the image who the father is.
