In 2034, the world was transformed by the "Ability Incident." Monsters emerged from another dimension, some humans awakened special abilities, and even those who made contracts with demons appeared. The world split into factions named after the seven deadly sins, and conflict raged on.
Among them, the girl called the strongest, Ruka Shishiuchi, threw herself into a final battle to protect her comrades and lost her life.
But when she next opened her eyes, she had returned to five years before the Ability Incident—2029.
"...I can still redo everything."
Knowing all about the comrades she lost in the previous world, the cities that fell, and the mastermind who killed her, Ruka begins to move to change the future this time.
However, changing the past also changes the future. Enemies that didn't exist in the previous world, and even new contractors with demons, begin to appear.
The second life of the girl who was once the strongest transforms not into a battle to save the world, but into a battle to create a "future that never should have existed."
