Also known as: 見返り, 振り返り, 振り向き, 振り向く, 見返り美人, 回眸, 回头看
A character turning their head, body or eyes to look behind themselves.
The subject's gaze should be directed fully or almost fully backwards over the shoulder, anywhere from 135 to 180 degrees behind them relative to their front.
Oftentimes combined with From Behind and Looking At Viewer, and also Sideways Glance if the character's body is partly facing away.
If the character has both of their eyes closed, use Facing Back instead.
