Occult: (
Story/Location) Titles involving the action or influence of supernatural agencies or some secret knowledge of them.
Violent: (
Objectionable Content)
Titles that include as an important part of their content excessive displays of cruelty, blood and gore. Any of the classical 'slasher' films would qualify for this keyword. The series
Black Lagoon would be a good example; as many of its chapters involve killer lolis, chainsaw mercenaries and flying body parts.
OVA: (
Type) OVA = Original Video Animation. These are the direct-to-video anime titles done in Japan. Often, OVAs can start a franchise (
Tenchi Muyou! Ryououki), start a TV series (
Mahou Tsukai Tai!), be a sequel to a TV series (
Love Hina Again), or be a stand-alone title (
Aa! Megami-sama! OVA). Sometimes, the OAVs are named the same as the TV series and thus will sometimes have the term OVA listed after the title's name to separate it.
