You know an Episode for an Anime that's not listed...

AniDB is a user-driven database and every user can add new episodes. So if you know an episode for an existing Anime-title that's not yet in AniDB we encourage you to add it. We also ask you to include as much info as possible when adding a new episode, it's for all users' benefit.

Where can I add new Episodes?!

At the bottom of every anime entry is a link names "Add Episode". Once you click it you're on the "Add Episode" page. There's a lot of info you can input here.

Basic info you should include when adding an episode

Episode number

Be careful with different episode orders here. For the moment the Japanese "how it was supposed to be shown" order is our standard.


  • Normal Episode
  • Special/Extra Episode (DVD Specials, Bonus eps) (S1, S2, ...)
    • Live-action bonus material included with a BD/DVD release are classified as S episodes.
    • Live-action material that was released standalone should not be added; rare exceptions may apply.
  • Opening/Ending Episode (C1, C2, ...)
Note Do NOT add a separate episode for creditless openings/endings. Set the creditless flag in the video track of the file instead. We don't want creditless and non-creditless as separate episode entries.
The ONLY VALID naming template is Opening (1,2,...,n), Ending (1,2,...,n). In case if the same song is used with a significantly different video or the same video is used with a different song, append letters after the numbers e.g. Opening 1a, Opening 1b. For foreign OP/ED episodes, if they differ from the original Japanese versions, append the country name before Opening (1,2,...,n), Ending (1,2,...,n).
PVs (music video for the song) go under Other episodes, but only if they were released as part of the anime DVD/BD.
"Long/full" versions of the OP or ED should be added under Special episode unless they were actually used within a regular episode.
If the OP/ED song is played and credits are shown, but the video is still that of the regular episode, then it's NOT an OP/ED episode (rather common in last episodes as sort of an epilogue).
OP/ED episode's display name will be automatically changed to the song played in that OP/ED if the song has the appropriate OP/ED episode number relation added. It will also automatically display the episode range the OP/ED is played in if the song has those episode ranges added.
OP/ED episodes, like any other episode, should have the air date, which would be the air date of the episode they were first played in.
  • Trailer/Promo/Commercial (T1, T2, ...)
  • Parody Episode (P1, P2, ...)
  • Other Episode (US Chopjobs & certain supportfiles (AC3 modpacks, fontpacks).) (O1, O2, ...)
Note "Other" is NOT meant for OST's, Manga, AMV's or any other not official Special!
Disc menu animations are also not welcome in AniDB. Please do not add them.

Episode Name

These basic principles apply to all episode titles of all languages and all episode types:

  • Do not include the anime title in the episode title. The anime title is an "anime title", and therefore not an "episode title" and not to be included as any portion of any episode title; anime titles are stored in the anime entry. This applies to all episode types, and all languages.

English Title General Guidance

These basic principles apply only to English episode titles:

  • Check the official page if it is licensed, with an English title available. If it is not, use a translation of the romaji/kanji title.
  • If neither are available, use "Episode XX" where XX is the number of the episode. For OVAs, use "Volume XX".

Stylized Episode Numbers

Episode "titles" such as "Operation 9", "File #002" or "XYZ第一話" or "ABCの第三話" etc. are considered to be stylised episode numbers rather than episode titles.

  • When they prepend the main episode title, do not add them or their transcriptions/translations to the title.
  • When they appear standalone as the only thing in the episode title, use the default "Episode XX" or "Volume XX" naming convention instead.

"Prologue" and "00" Episodes (For English Titles)

When it comes to episodes that are numbered as "Prologue" or "00", unless there is a "clear indication" that an "episode 0" should NOT be considered as the first episode of the regular airing sequence, an episode 0 will be considered episode 1 on AniDB, as it is the first aired episode.

Examples of "clear indications" for what "episode 0" entries should NOT be considered as the first episode of the regular airing sequence:

  • Macross Delta -- episode S1, Battlefield Prologue, this is essentially a trailer of the first episode
  • Chaos;Child -- episode S1, Chaos;Head, this is a recap episode of the prequel series

For reference, the original discussion on AniDB's moderator IRC channel can be found here, along with follow-up comments here.

In Summary: when an "episode 0" is considered as episode 1 on AniDB

  • An episode note should be added to provide a brief description. For example: "Listed as Episode 00"
  • We will apply the following episode title naming convention, to make it explicit that it is an "episode 0":
-- "Episode 0: xxxxx: yyyyy - zzzzz",
-- "Episode 00: xxxxx: yyyyy - zzzzz",
-- "Prologue 00: xxxxx: yyyyy - zzzzz",

Etc, where:
xxxxx: yyyyy - zzzzzz
Represents our general title naming convention of:
Main_ep_title: sub_title - sub_sub_title

Guidance for T episodes

T episodes include PV (preview), CM (commercial), Trailer, etc. (non-exhaustive list); essentially, anything that generally serves the purpose of promoting an anime is a T episode. Generally, T episode naming guidance is as follows:

  • If available, provide the Japanese T episode title in full.
    • For example: A PV posted on the official website (directly embedded, linked to YouTube or some other video service, etc.) would have an official title from the producer/distributor as written on the website (preferred) or as provided in the video's name or title card.
    • For example: A web PV posted on the official YouTube would have an official title from the producer/distributor
    • Do not include extraneous bits in the title, such as "- Netflix", that are metadata not part of the actual functional title of the PV.
  • If a Japanese title is given, transcribe it in full.
  • For the English title, the general naming convention is as follows: <<Type>> <<#>> (<<Length>>): <<Description>> - <<Sub-description>>
    • Type: type of T episode, e.g. PV, CM, trailer, web PV, BD/DVD CM, etc. (non-exhaustive list). More descriptive terms are preferred, but terms should still be kept as short as practicable (e.g. do not expand "BD/DVD CM" to "blu-ray and DVD commercial").
    • #: number the various T episodes based on airing order, for each type. For example, if the anime has 3 PV and 4 CM, number them PV 1, PV 2, PV 3, CM 1, CM 2, CM 3, CM 4.
    • Length: provide the length in (m:ss) format. For example (1:36), (12:35). Given that most T episodes do not have formal titles, the exact length helps to track the T episodes, as it is otherwise very difficult to tell the T episodes apart.
  • Whenever possible, try to add a short and uniquely identifiable description of the shown content to the Note field of the episode, especially if that trailer or commercial is not available on the Internet. Good descriptions help immensely with identifying files from different releases whose labeling and ordering does not match with other releases or our episodes.

Example: PV 5 (24:00): Public Anniversary Special

The general naming convention is not universal. Use some discretion for special cases. Examples:

Play Length

The play length of this episode. If over 10 minutes, round UP to the nearest multiple of 5 minutes (The only acceptable case to round down would be if it's just a few seconds over the gap. You can file that under cornercase.). If under 10 minutes, rounds UP to the nearest minute.

Ordering of S Episodes -- GENERAL GUIDANCE

There are no hard rules regarding the ordering of S episodes. However, the following general rules of thumb should be applied:

  1. "Actual episodes" should come first before recaps. Example: Bakemonogatari episodes 13 to 15 (S1 to S3)
  2. "Recaps" should come first before "specials". Example: 91 Days episode S2
  3. "Specials" Specials (e.g. web streamed specials, DVD and BD bonus content, etc) should come first before live action entries.

Further to the above, the following overall guidance should be used to group and order the above subgroups:

  • Internally within the above categories, group like items together. Example: Girls und Panzer specials, similar specials are grouped together (e.g. the "War" BD specials, Tank Courses, Character Pictures, etc)
  • Internally within the above grouped like items, sort episodes by release date

Above all else, common sense should apply. These are general guidelines, and each anime should be looked at on a case-by-case basis.

Guidance for O episodes

General Guidance

O episodes are not intended as proper episode entries. O episodes are used as a placeholder for entries that are a chopjob, re-cut, or other combination of regular (R), special (S), Opening/Closing (C), and/or Trailer/Promo (T) episode types.

  1. To ensure that mylist statistics work correctly, it is mandatory that all files contained in O episodes are also assigned other episodes using file-episode relations.
    1. Use file-episode relations to mark which episode(s) the O episode covers.
    2. Assign percentages based on how much of the target episode this file covers. For example, if an O episode covers time timestamps from 20% to 40% of episode 1, and timestamps from 65% to 90% of episode 2, add these as the percentages in the file-episode relations.
  2. If an O episode covers multiple regular episodes, for example a single release covers episode 1, 2, and 3 of the main series, THIS IS NOT AN O EPISODE. Instead, add the file to episode 1, and create file-episode relations to episode 2 and 3.

Movies subsequently redistributed in TV series format

Some anime series are distributed in both a movie and a TV series format with minimal edits between each other, except for the addition of opening and ending segments; the first airing or screening of the anime determines the anime type set on the anime entry as is usual. In case of a movie released also in an episodic format, the episodic version is to be added using a set of O (Other) episodes.

Files for a TV distribution like this are expected to be added into said O episodes. However, to make mylist statistics for said anime to work correctly, it is mandatory to also assign the file to the episode entry of the relevant movie, using an additional file-episode relation; there is no difference in treatment from the general guidance.

The start and end positions saved into this relation also make the part number inside the movie entry explicit. Therefore, notes such as "Part X of Y" are generally considered both duplication of information and an unwelcome complexity. Use of these types of notes are discouraged, especially given that the average user usually only cares about the TV edit episode number in these circumstances. These notes can be allowed if their use clearly adds clarity to the case, but always ask a mod first before adding such notes.

Optional Info

We'd like you to add this info sooner or later to the episode since some other users will benefit from your work.

Episode Name (Romaji)

Please check our Kanji & Romaji Guideline for further assistance with this.

  • For OVA (complete ep#=1)
    If there is no real ep title (aka when the ep title = anime title) just leave the field blank
  • For Movies
    Just leave the field blank.

Episode Name (Kanji)

Please check our Kanji & Romaji Guideline for further assistance with this. allcinema is a reliable source for this.

  • For OVA (complete ep#=1)
    If there is no real ep title (aka when the ep title = anime title) just leave the field blank
  • For Movies
    Just leave the field blank.

Episode Name (Other languages)

Please check:

  • The dub itself (if any)
  • The DVD cover (if any)
  • The official website (if any)

First Aired/Released Date

Main article: Content:Anime#General Guidance

Generally, the Japanese/Chinese/Korean/Asian air date is the first and most precise airing/release date worldwide for both individual episodes and the anime as a whole. Check the official Asian page, allcinema, the Japanese TV Guide (explained here), or other pages listed here.

The Western air date should only be used if the Western airing is materially earlier than the Asian one. Otherwise, use the air date in the home market. For example:

  • When the Western simulcast of a Japanese anime is 5 hours earlier, causing a 1-day date mismatch with Japan due to timezones, use the Japanese date.
  • When the Western TV premier is 3 months earlier than the Japanese release, use the earlier Western date. For example, FLCL Progressive first aired on US channel Adult Swim's Toonami block as a 6-episode series from 03.06.2018 till 07.07.2018. It did not air in Japan until 28.09.2018, where it was released in a movie format.

Japanese TV Schedule Timestamps

Be careful with shows that have 24:00 and later air hours - this means that show will air on the night after the specified date. For the purposes of AniDB, a show listed as airing between 00:00 and 23:59 is added with the listed date; any show airing on 24:00 or later is added with the "first aired" date of the next day.


Japanese TV schedule says: 24.03.2005 25:30
this means it aired:       25.03.2005 01:30.

Such an episode would be added as "first aired on 25.03.2005".


This field should only get used for pure recaps!

Note Do NOT use this field to mark "filler" episodes or write general episode summaries!

How to Remove bad entries

If you added a bad entry yourself you can remove it as long as no one added a file to this entry. Otherwise, please post the eid of and a link to the entry to be removed here: Change Requests forum
