Frey Raon Starlight was the hero who killed his family and comrades and destroyed the world. His goal was to return to the past, unlock a "hidden route" to truly save the world, and achieve peace.
As planned, he successfully returns to the past and gains access to the hidden route. However, his relief is short-lived as he is confronted with an unexpected truth: the five heroines he killed in his previous life have retained their memories and are now trying to kill him...!
Can Frey, under such extreme circumstances, save the world this time?
