The Disastrous Life of Saiki K. (Japanese: 斉木楠雄のΨ難, Hepburn: Saiki Kusuo no Sai-nan) is a Japanese manga series written and illustrated by Shūichi Asō. Following a series of one-shot chapters published from 2010 to 2011, the manga was serialized in Shueisha's shōnen manga magazine Weekly Shōnen Jump from May 2012 to February 2018. It was followed by a short serialization of 4-panel chapters published in the same magazine, and two one-shot chapters published in Jump GIGA in May and July 2018.

Kusuo Saiki is a high school student with an extraordinary secret—he possesses a wide array of psychic abilities such as psychokinesis and teleportation. Despite his powers, he goes to great lengths to conceal them from everyone at school. Throughout the series, Kusuo finds himself in seemingly ordinary scenarios where he discreetly employs his powers to navigate through challenges. Along the way, he encounters a host of unique individuals, each presenting their own set of problems. Despite this, Kusuo cleverly uses his abilities to resolve these issues without drawing attention to himself.
Later on, Kusuo reunites with his brother, Kusuke, after his limiter is broken. Despite the challenges they face, they manage to stay in touch. Eventually, Kusuo receives a "limiter" that removes his powers. However, he later regains his abilities and learns that he belongs to a different species than humans, as his body has adapted to having powers. This revelation adds a new layer of complexity to his already extraordinary life.
