Also known as: 発情, 蒸れ, メスミスト
Steam that is visibly emanating from a character, rather than an environmental source. It may be because the character is Hot and Sweaty, or be used to emphasize the "steaminess" of an erotic scene.
Not to be confused with Breath.
Use Head Steam if the steam originates only from the head and the cause of the steam is embarrassment.
