A subset of sadism, focused on men in (usually extreme) physical pain, particularly in an eroticized and/or humiliating way - the inverse of ryona.
Tends to cover two categories, the first being largely mixed-sex combat/femdom images where the male character is a supplement to an image focusing on his assailant, while the second is simply art focused on men in severe pain.
Often focuses on pained facial expressions, bruises, blood from the mouth or nose, etc. Usually entails the pain being inflicted by another party rather than self-inflicted.
Can sometimes overlap with guro, though not all guro posts focusing on men are reverse ryona. May overlap with abuse as well.
