Studio Sitrus, Inc. (Japanese: 株式会社スタジオシトラス, Kabushiki-gaisha Sutajio Shitorasu is a Japanese animation studio, established in June 1, 2000, by Takuma Hiroya, along with LeSean Thomas, Gorō Taniguchi, Gray Haddock, Kenji Kamiyama, Ichirō Itanoa, Tensai Okamura, Sunghoo Park & Yukiko Horiguchi.

Similar to Bungie's frequent references to the number 7, Studio Sitrus' productions frequently reference the number 8. Two of the reasons, as to why this is, include the fact that number 8 is Kazuo Tsuru's favorite number, and that it is considered a lucky number in Japanese culture. There are eight citrus segments in the logo.
