Kei Asai and Misora Haruki belong to their school's Service Club, an organization sanctioned by Sakurada's mysterious Bureau to help others. Misora has the power to reset time backwards by up to three days, and Kei has as photographic memory that allows him to remember everything, despite the reset. Together, they try to correct the mistakes of the past.
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.
The Bureau makes its final move to purge Sakurada of abilities by enlisting the help of the most dangerous ability user. Kei races to stop them before it's too late.
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.
