Just... as a gentle FYI, non-game or culture specific terminology (yandere, everybirdie) is better off avoided in explanations to avoid confusion. Because I'm honestly kind of more confused than before regarding what you're trying to say here. If this ability is honestly so vague in canon that you're not able to expand upon it reasonably to someone canonblind, it may be worth rethinking as an Echo request. And after me rereading it three times, squinting really hard, and still not really getting it -- yeah. That's a problem. In addition, the "has to be inferred" portion implies that this is basically headcanon, and I'm wary of approving those without some justification behind it.

Basically, I'm going to need a more legible, condensed version of this before I can approve it.
