From MangaHelpers:
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.

Mahiro thought she was all alone in the world until her long-lost brother, Ren, and his handsome, mysterious friend showed up and turned everything upside down! Competent, determined and dangerous, the two men have vowed to protect the innocent girl from the ruthless Queen Phibula, who is hell-bent on seeing her dead. As Mahiro learns more about her forgotten past, she and her handsome bodyguards must face explosions, assassins, betrayal... and the promise of blossoming romance.

From Wikipedia:
Pilgrim Jäger is a historical fiction that takes place in Europe in the year 1521, at the time of the Protestant Reformation. The story follows two women, Adele the acrobat and Karin the fortuneteller. Afraid of being accused of witchcraft, they disguise their special powers, working as common performers (professionisti) to earn enough money to buy indulgences from the Catholic Church that will hopefully free them from their sins. However, their powers soon get them involved in a great religious battle involving the Medici family, the Este family, Girolamo Savonarola's "prophecies," and many others.

"I don't believe in god and men."

With the help of a frivolous childhood friend that seems to see through her, can she move on and smile again?

Even though J no Subete is three volumes long, each volume is a dynamic story in itself covering a particular stage of J's life. Her life is a dark story and it's a very psychological manga.

Book one is about all of J's trials and tribulations throughout childhood, during high school as she tries to find her place in the world and when she meets the somber honor student Paul...
