Artwork depicting a subject that isn't from any established copyright. Basically, art that is not fanart.
Make sure to confirm that the art really is original before you add this tag. Google character names or search them on animecharactersdatabase.com.
Some art may depict original subjects alongside subjects from an established copyright. In this case, the art should be tagged as original and with the tag for the copyright.
If the artwork shows a different artist's original character, include the borrowed character tag as well.
Most original artworks on Pixiv are tagged with:
- オリジナル ("Original")
- 創作 ("Creation")
- 原創 (Original via Taiwan artist)
- 原创 (Original via China artist)
- 看板娘 ("Poster Girl" of Artist's Webpage)
- 自キャラ (Own Character)
- オリキャラ (OriChara)
Note: Some works on Pixiv are occasionally tagged original by accident. Art by the character designer for an established copyright also sometimes tag their work as original—on Danbooru, these should be tagged with the corresponding copyright instead.
