Incest

Incest is defined as romantic or sexual relations between people classified as being too closely related to marry each other. On Anime-Planet, we apply this tag when: 1) the characters are related by blood, or 2) the characters are related through adoption or marriage and have a long history together. If characters have just met through marriage and develop a romantic relationship, even if the taboo aspect is discussed, we do not apply this tag.
