Manga typically caters to five major categories of readers. Shōnen mostly offers action-packed and light-hearted stories for young and teenaged boys. As they grow older, boys can move on to seinen, which contains darker and more mature themes.  Shōjo is often romantic or adventure-based. It is designed for young girls and tweens. Manga for older female audiences are called Josei, and feature slice-of-life, romance, comedy, or adult themes. Lastly, kodomomuke or kodomo refers to manga packed with good morals and lessons. These are specifically created for toddlers or younger kids.
