Kusuo Saiki is a high school student who possesses a wide range of psychic abilities. While many may believe these abilities to be a gift, to Kusuo, they are a curse as he must fight strange odds in order to try to live a normal life. Forced to use his psychic powers to protect his secret or to make up for his father's incompetence at work, will Saiki eventually come to realize how his powers can actually help his friends and family?

The ground shakes, a rumble follows, and before anyone in Japan can prepare themselves, a cataclysmic volcanic eruption engulfs the country in molten lava and suffocating ashes. Of course, high school student Kusou Saiki repeatedly uses his psychic powers to prevent this harrowing catastrophe. But between restoring the planet and watching his friends discuss their aspirations, Saiki finally resolves to stop the eruption and allow the world to continue spinning. However, this straightforward task is challenging even for the most powerful of psychics, let alone one who must deal with the usual shenanigans his ludicrous friends present.
