Synopsis
Himouto! Umaru-chan centers around Umaru Doma, a seemingly perfect and popular high school student.
However, her life takes a comedic turn behind closed doors at home, where she transforms into a spoiled, lazy, and otaku-like little sister, much to the dismay and amusement of her older brother, Taihei.
The anime follows their everyday life together, focusing on Umaru's antics and Taihei's efforts to manage her. It also explores Umaru's relationships with her friends, creating lighthearted and humorous situations.
Ultimately, Himouto! Umaru-chan is a slice-of-life comedy about siblings, friendship, and the contrasting sides of Umaru's personality.
