Yumi Sudō wields psychokinesis as her core psychic ability. She teams up with two other supernaturally gifted girls to establish the Gakuen Choujo-tai, a group dedicated to upholding justice and protecting peace within their high school. Her powers, like those of her teammates, remain underdeveloped due to their collective inexperience in controlling and applying their abilities. A pivotal moment arrives when a terrifying dream strikes Yumi, which she interprets as a genuine premonition. This perceived vision spurs the trio to investigate the activities of a newly formed and rapidly growing psychic power research society at their school. Their investigation, sparked by Yumi's dream, leads them directly into a confrontation with a sinister plot orchestrated by this organization. Throughout the ensuing conflict, Yumi employs her psychokinetic abilities alongside her teammates as they combine their powers to counter the discovered threat.
