Green Green (グリーングリーン Gurīn Gurīn?) is a Japanese, 12-episode anime adaptation of the H-game of the same name. While there are no sexually explicit scenes in the first 12 episodes, the series has a strong focus on nudity. A non-canon sequel exists to the story as a thirteenth episode, which was released at a later date. This 'Episode 13' is unlicensed and not included in the US release due to scenes involving sexual acts.
