Himouto! Umaru-chan: Himouto Ikusei Keikaku

At school, Umaru Doma appears to be the ideal student with good looks, top grades, and a lot of talent. Once she gets home, however, she reverts into a layabout who spends her time lying around, playing video games, and constantly depending on her older brother, much to her older brother Taihei's dismay.

In the game, all of Umaru’s belongings have been taken away from her by Taihei so she can be more productive, but all this means is that the player will have to take care of her, and help her with her habits. When Umaru isn’t at home being lazy, the game switches to a visual novel format.

The game features an original story not seen in the manga or the anime.
