After losing his mother, 14-year-old Taro journeys to Tokyo to live with his grandfather. But he gets the biggest surprise when he discovers that his grandfather's home is a huge mansion with hundreds of beautiful maids ready to serve him. Making matters worse (at least for Taro, but not for our viewing) is that not only does he inherit the Hanaukyo mansion, he gets the services of all of the maids 24 hours a day, 7 days a week.

Everyone in the world uses smartphone apps. But inside them lurks unknown creatures called "Appli Monsters," or "Appmon." The Appmon are AI lifeforms with the ability to think and act, and exist in the boundary between the human world and digital space. In the vast sea of the internet, the "last boss AI" Leviathan takes control of the Appmon with a virus and begins hacking every system, thus starting to control the human world from the world of the net. Haru Shinkai is led to acquire the Appli Drive, and uses it to materialize Gatchmon, a search app monster. (Source: ANN)

One year ago, a UFO containing 150 aliens crash-landed off the shores of Kasai. Because no one could fix their ship, the Japanese Government decided to bestow upon them the designation "DearS" and make them into Japanese citizens, teaching them the language, customs, and culture of Japan. However, in order for them to become more familiar with human society, a home-stay program has been enacted to allow them to mingle with other humans. One misty morning, a truck carrying a capsule that housed one of these aliens ends up dropping it into the riverbank, releasing her from her confinement. She is eventually found by a high school student named Takeya Ikuhara, who saves her from being hit by a truck and takes pity on her, despite being extremely distrustful of their race and wanting nothing to do with them. Upon being named Ren, she imprints upon him as her "Master" and serves as his personal "Slave," leaving him with a "DearS" who wants to remain with him no matter what and bringing his ordinary, alien-free days to an end.
