Even the most casual of anime and manga fans are likely familiar with the terms "shonen" and "shojo." Shonen and shojo series represent these mediums' most popular properties, from One Piece and Naruto to Sailor Moon and Fruits Basket.

However, these are broad demographics that continue to evolve after more than a century of storytelling and experimentation.
