Taichi Shimamura

A sage travels to the past and collects a set of eight legendary swords, which bring to life a gang of talented but dysfunctional young warriors. The warriors know that Nobunaga Oda was supposed to die at the Honno-ji incident in 1582, but in this timeline he didn’t. To revert back to the original history, the warriors must travel back in time to assassinate Nobunaga Oda.

A long time ago, there was a psychic boom on television, and among the children who watched it, some developed special abilities. However, it was rare for children who awakened to psychic powers to achieve great things, most had minor abilities, and only a handful were able to make a name for themselves as psychics. Akira is one of these psychics who has no place to shine, so he gathers together psychics with similar circumstances and forms Team Psychicker Z.

Office worker Kako Hoshino develops the ability to time travel whenever she is surprised. She would travel back in time for several minutes with the person who surprised her. Therefore, she tried to avoid contact with other people as much as possible. A chance of love was about to come her way, but she's surprised by the clumsy Chizuru, and time unintentionally rewinds, ruining the chance. Despite this, Kako and Chizuru, who were not particularly close at first, gradually grow closer. She begins to be pursued by people who want to take advantage of her ability, and is warned that her time travels could potentially cause the world to collapse. Troubled, Kako teams up with Chizuru to try and cure her troublesome condition.
