Depression: (
Story/Location) Titles that contain characters who suffer from depression would fall into this category if this is of significant importance for the storyline.
Tragedy: (
Genre) Animes of this type have tragic events as an important part of the story, and usually will show how the characters are dealing with the consequences of that tragedy (more or less successfully). This doesn't necessarily mean the story cannot have a happy ending as the tragedy might occur during the first episodes of even before story begins; as such this category information need not be a spoiler (unless the tragedy were to be a surprise for the audience in a mystery-style show).
Dating Sim Spinoff: (
Type subgenre) Usually an anime starts out its life as a manga but a Dating Sim can also become an anime. Dating sims follow a set choice or path and feature Bad, Good, and True Endings. Most of the Dating Sims though are
↗ero-based an usually involve the main character trying to 'date' each of the girls in the game; the anime usually picks one of the harem of girls available and plays her 'true ending' out. Other dating sims are not usually Ero in nature but still follow the other rules. Note that even an anime based on an Ero game may not contain any erotic scenes in many cases. See also: "
Video-game inspired".
