La ville de Sakurada a une particularité. En effet, près de la moitié de ses habitants possèdent des pouvoirs surnaturels. Nous suivons le quotidien de deux lycéens. Kei Asai est capable de se souvenir avec précision de tout ce qu'il entend ou voit. De son côté, Misora Haruki peut retourner dans le passé dans la limite des trois derniers jours.

Tous deux sont membres du "Club de service" de leur établissement scolaire qui sert à l'administration de la ville afin de surveiller les gens dotés de pouvoirs pour faire régner la paix. Nos deux héros utilisent ainsi leurs pouvoirs ensemble afin de résoudre certaines affaires puisque Kei parvient également à se souvenir des événements effacés par la capacité de Misora.

The Bureau comes to take Mari, away. Using Misora’s Reset ability, Kei goes back in time to stop the event from happening. However, doing so may come at great cost.

Kei and Misora receive a Service Club request to revive a dead cat, but the request, and the intentions of the client, raise more questions than answers.

A dead cat, a ghostly friend, and a client with dark motives. With Kei and Misora’s lives in danger, Misora resets, putting them back at the start of their strange case.

When Kei and Misora first joined the Service Club, they took a case involving a girl trapped in a marble. Before Misora resets, Kei tries to understand the girl’s ability.

A client appeals to the Service Club, claiming that a girl with red eyes has stolen his ability. As Kei investigates, he learns more about the Macguffin’s mysterious history.

Misora resets after Eri tries to steal her ability. With only a few days left, Kei tries to understand what connects Eri to the MacGuffin, the old man, the witch, and Sumire.

Eri Oka remains at large, and Kei has another encounter with the Witch within an old photo. With both of their lives at stake, what can he do to save them both?

Two years ago, Kei and Misora got involved in their first case: helping a young boy. With the shadow of Sumire’s death hanging over them, Kei decides to investigate her death.

Kei begins to develop a plan to meet Sumire again, just as the witch said. As his theory takes shape, he wonders if reviving a dead girl is the right thing to do after all.

Friendship is still a foreign concept to Misora. After an attempt to hang out with Seika, Misora discovers that Kei is sick and might need a friend to nurse him to health.

With his goal met, Kei must now deal with the reality of Sumire’s existence. At the same time, he begins investigating an ability that takes people in the world of dreams.

The mechanics of the dream world are still wrapped in mystery. A visit to the "Stray Cat House Man" may shine some light on the truth.

Kei and Misora meet with Chiruchiru, which leads to a very interesting conversation where more truths are revealed about the world.

In the dream world, there was God, a monster, and a girl. As Kei pieces the mystery together, he asks Misora to Reset in hopes of saving another lost soul.

Sumire begins to manipulate the strings that bind the fate of those in Sakurada. Meanwhile, Kei tries to find the balance in his relationship with Misora.

A series of incidents involving ability users raises a red flag in Kei’s mind. Someone is manipulating memories in Sakurada, but why?

The Bureau’s plan begins to accelerate. Sumire visits Kei and reveals why she had to die. Misora, meanwhile, finds herself in Masamuna’s cross-hairs for ability removal.

Abilities begin to fade, and even Kei is losing his memory. With Sumire and Misora living as their middle school selves, are all their memories doomed to be rewritten?

With Misora’s Reset, Sumire manages to gives her precognitive abilities to Kei. Using both their abilities, Kei makes a last attempt to stop Masamune’s plans for Sakurada.

To stop Masamune’s plan, Kei approaches the last person he can think of for help: Eri Oka. Using the Reset, Kei tries to devise a plan to save abilities in Sakurada.

Would Sakurada really be better off if abilities didn’t exist? Kei and Masamune’s values clash as they both try to define the true meaning of reality.

Sumire collapses and no one can wake her. To save her, Kei returns to the dream world where she gives him an ultimatum that may cost him his life.
