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.
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).
