The "Heaven's Door" activation gesture here seems to be from Kishibe Rohan wa Ugokanai live-action series (see first 5 seconds of this), rather than Diamond wa Kudakenai (where Rohan scribbled in the air to activate it) so I'm retagging this and the child post.
I'm going with faux_traditional_media because of how sharp the transition is from the character to the text. The way the colour builds up on her dress looks artificial to me, too.
