Shōjo manga (少女漫画), also romanized as shojo or shoujo, are Japanese comics aimed at a young teen female target-demographic readership. The name romanizes the word 少女 (shōjo), literally meaning "young woman". Shōjo manga covers many subjects in a variety of narrative styles, from historical drama to science fiction, often with a focus on romantic relationships or emotions.

Shōnen manga (少年漫画), also romanized as shonen or shounen, are Japanese comics marketed towards young teen males between the ages of 12 and 18. The kanji character 少年 (shōnen) literally means "boy" or "youth", and the character 漫画 (manga) means "comic"; thus, the complete phrase means "young person's comic", or simply "boys' comic", with the female equivalent being shōjo manga. Shōnen manga is one of the most popular and best-selling form of manga.
