The Wasted Lite is a place in the anime series. Located down in the Underworld, it has a multitude of features and, because of said fact, the Wasted Lite can be considered a nightclub just as much as it can be referred to as an ordinary bar or tavern. Despite these advantages, however, many have realized that it is very small on the outside, akin to a "miniscule cellar", if you will; the Wasted Lite as a building was apparently made to fool patrons into thinking that its exterior is gigantic in comparison to the interior, when it's really the other way around.
Ren Ushikaze is this joint's barkeep, albeit unofficially.
