When Suzuki Oji enrolled into high-school, he was hoping for some kind of excitement to occur in his life but he never expected it to take the form of Kuromori Kisaki, a descendant from a 400 year old clan of witches. However, Kuromori needs a special brooch in order to fly on her broom, something she lost when she landed on Suzuki after he had mistakenly thought she was falling to her death. Although he initially thinks Kuromori is being unfairly difficult to socialize with due to her "witch" status, he finds and returns the brooch to her who out of gratitude, shows her flying magic to him. Suzuki then questions the possibility of himself flying by also wearing the brooch, but right after Kuromori pins it to his coat, both of them suddenly find themselves several feet in the air before falling into the school's swimming pool. So just who or what is Suzuki...?

One day, an ordinary high-school girl named Minase Youmu is kidnapped up in the mountains. Her kidnappers claim that she has taken some kind of "medicine" and that there's no going back. Luckily, though, a former detective named Sanpouji Kotetsu happens to pass by where she is being held, and rescues her. Kotetsu hastily gets the underage girl to the police, where the investigator Naru Asuka and her 'psychic' partner Hayama Reiichi take on the girl's case. Asuka, Reiichi and Kotetsu have to figure out who took Youmu--and what was done to her--before it's too late (if it isn't already)! Source: MangaHelpers

From [MangaHelpers](https://www.mangaupdates.com/groups.html?id=1011): Nearly half the population of Sakurada, a small town near the Pacific Ocean, has some sort of unique power. These powers range from being able to enter the mind of a cat to resetting the world back to a certain point in time in the past. There is a group known as the "Kanrikyoku" that controls and monitors the use of these powers. Asai Kei and Haruki Misora work for their school's club called "Houshi" club, which execute any missions received from the Kanrikyoku. Misora has the ability to reset the world three days. This means that all events and any memory of the past three days that "could have" happened, never happened. Kei has the ability to "remember" the past. Even after Misora uses her powers to reset the world back three days, Kei will retain those three days in his memory. Combining their powers, these two solve missions issued by the Kanrikyoku.
