Do We Have This? This is an Anime Trope. Sometimes, if an anime character becomes extremely depressed, the background will fade to a very gloomy black and the character will appear to sink into the infinite Void of Despair. This tends to happen when someone points out a particular physical trait that the character in question is not proud of; or an emotional trauma occurs in the Love Triangle. There is often a follow-up shot using Corner of Woe and/or Color Failure, demonstrating the character did not fall into a literal Void. Needs More Examples! Needs a Better Description. Up for Grabs.
Hello, Unknown Troper. You'll need to get known to lend a hand here.
