Premise
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.
