Short: (
Type subgenre) This category contains titles whose playing time is unusually short as compared to the length of standard anime episodes (which are roughly 20 minutes plus intro & trailer).
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.
Sequel: (
Type subgenre) This is a title which continues a series. It may have a different name but is
canon material.
