The appearance of a faint white or grey fog or glow around and above objects and people during a rainstorm. This is a representation of a real-world phenomenon — a kind of mist generated by the shattering of raindrops impacting on a surface — which normally can only be seen under the right angles and light conditions, but which in anime can be seen all the time during a rainstorm. Adds an almost otherworldly air to rainy scenes, but also makes drawing rain much easier.
For technical reasons, this trope is more ubiquitous in animation than in live-action productions.
Anime & Manga
- Dual! Parallel Trouble Adventure: The "D digging in the dump" scene.
- Kamichama Karin: The scene when Himeka and Kazuno walk under the rain while sharing an umbrella is accompanied by dense, white fog.
- Negima! Magister Negi Magi: During Sayo's flashback episode.
- One Piece:
- Puella Magi Madoka Magica: In "The Only Thing I Have Left to Guide Me". Miki Sayaka's funeral is held under the rain, with an off-screen character narrating the details of her disappearance and death. As the camera pans out to a shot of the city, a white fog over the ground can be seen. It has to be noted, though, that there's no such thing when the camera is closing up in the characters and funeral scenery.
- Sailor Moon: Played for Drama when Usagi's love interest walks away from her with his umbrella, poignantly averting Together Umbrella.
- Str.A.In.: Strategic Armored Infantry: Seen in a flashback to James and Annie's funeral.
- Sumomo Mo Momo Mo: Momoko, episode 13.
- Yotsuba&!: Used whenever it rains, most prominently in "Yotsuba & Heavy Rain" (Chapter 7) and "Yotsuba & Typhoons" (Chapter 52). The gap between the two is a nice example of the series' Art Evolution; the effect is much more convincing in the latter chapter.
- Les Misérables: This is simulated using a fog machine for the song "On My Own", in which Eponine sings about how the rain makes the pavement look like silver.
- Teen Titans: The episode "Haunted" subtly gives away that Slade is not actually there because everyone but him is covered by a faint, white aura.
- Winx Club: While this trope is generally averted (e.g., 'The Mysterious Stone' and "Valtor's Box"), there's one instance where it happens. In "The Fall of Magix", the black water that spawns the Army of Decay comes from a black magic-generated storm. As the insectoid creatures that comprise the Army are getting formed for the first time, a grayish, dense fog forms.
- Go somewhere that's at once miserably hot and horridly humid. Stir in one (1) cloudburst. Observe the steam rising from the pavement. Repeat as necessary.
