HOW MUCH IS LIFE TRULY WORTH?
Kusunoki used to believe he was destined for great things. Ostracized as a child, he held on to a belief that a good life was waiting for him in the years ahead. Now approaching the age of twenty, he's a completely mediocre college student with no motivation, no dreams, and no money. After learning he can sell his remaining years-and just how little they're worth-he chooses to divest himself of all but his last three months. Has Kusunoki truly destroyed his last chance to find happiness...or has he somehow found it?

But before they can rekindle their old feelings for each other, the clock strikes six and Kanae finds himself inexplicably thrust forward four days into the future. Worse, he learns that Akito, Akari’s older brother—and Kanae’s childhood hero—is dead.

Except death might not be the end for Akito. As Kanae tries to fill in the four-day gap of his memories, Akari explains: he’s about to relive those four days in reverse order in a phenomenon known as “Rollback.” Kanae himself explained it to her…in a past he hasn’t yet experienced. Armed with this new knowledge, Kanae is determined to leverage Rollback however he can to save Akito’s life—and Akari’s heart.

Growing up in a dreary suburb, Sakuma has little to brighten his humdrum days aside from his best friend. The bright, talented, and attractive Ushio seems to have everything Sakuma lacks, and his academics and athletic prowess make him popular with the girls at school. Past trauma—and an understandable inferiority complex—slowly drive the two apart, and by the time they enter high school, they hardly even speak anymore. Thus, Sakuma finds himself alone.

Against all odds, he eventually gains a friend in Natsuki, the sweetest girl in class. The two hit it off gushing about their favorite novels, and he falls head over heels for her. But that very same night, he stumbles upon an unexpected sight while walking through a familiar park: his old friend Ushio, dressed in a full-blown schoolgirl’s uniform and sobbing uncontrollably.

Sakurada Reset

Status: Finished

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 3 days. This means that all events and any memory of the past 3 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 3 days, Kei will retain those 3 days in his memory. Combining their powers, these two solve missions issued by the Kanrikyoku.

"The loop won’t end until someone is killed."

A long-standing amusement park, Sunny Park, is the subject of an eerie urban legend: "The man-eating amusement park, where those who enter disappear one by one."

Despite the rumors, Ryuzaki Kashio visits Sunny Park with her high school friends, expecting nothing more than a fun day of rides and attractions. But as the day draws to a close without incident, one of her friends, Koneri Nana, suddenly leads her to a secluded area—where she stabs her with a knife. As Kashio lies dying, Nana pleads with her:

"Please… save Asebi-chan."

The next moment, Kashio wakes up—only to find that time has rewound to the morning of their arrival at Sunny Park. Overcome with confusion, she hesitantly relives the same day with her friends. This time, wary of Nana, Kashio keeps a close eye on her, but she shows no suspicious behavior. The day ends, the park closes, and as Kashio steps through the exit gate—

—she wakes up again, back at the morning of their arrival.

As Kashio struggles to comprehend what is happening, a mysterious high school girl appears before her. She introduces herself as Kodera Asebi and tells her the truth: She is trapped in a time loop, unable to leave Sunny Park. And the only way to break free… is to kill someone.
