'Not powered as thought' image.
Image/AU whatever where they sort of assume Rumi's got some sort of protection to her because not only was her mother a Hunter but her father was a Demon so that must mean she has some sort of protection or power of her own.
Something Rumi herself is sure of cause Thirdlight has told her as much, she's a tiny Superhero you know? Like she has to be powerful they just don't know how yet.
As such with the confidence of a small child working on the wrong assumptions and reading too much into phrasing when she sees something going wrong she jumps in because she can protect her family when demons are attacking and they're outnumbered because she has power in her blood.
Except she doesn't. Thirdlight's injured, Rumi's injured, Celine losing her shit and fighting to the point of exhaustion is the only thing that saves all three of their lives that day.
And it's why they're so insistent that Rumi isn't a demon, she just has markings. She doesn't have any Demon magic to her at all, nothing like even the weak ones have, so obviously she didn't get anything else from her father which means she's not a demon, just... different.
