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."

In an island with a Christian influence, is where a high schooler Nazuna lives. She had hated men and stopped in believing in god due to her father leaving her, and never coming back, despite of countless prayers she sent. In result, she had turned into a nagging, unhappy girl. 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...

When the two were still young, Saito and Kawana Subaru were close friends. But with Subaru coming from a wealthy family, she was sent to the top school while Saito had to settle for a regular education.
But after painfully studying for years, he was finally accepted as a high school freshman through a scholarship program that only a handful of students are awarded. But what Saito thought was going to be a heartwarming reunion turned out horrible. Subaru had grown up beautiful and was the most popular person in school as she was kind to everyone, all except towards Saito who she seemed to despise.
Almost regretting his decision to come to the school, Saito wishes that somehow their dorm rooms would connect to each other. Magically, because it turns out that Subaru wished the same thing, their wish comes true but, in return, Subaru loses her self-control for one hour per day. During that time, her erotic desire for Saito, that she can normally hide, comes pouring out and her true intentions are revealed.
He wants to take advantage of this once in a lifetime chance but doing so might jeopardize their relationship during the other 23 hours.
