(Comprehensive) It Is Impossible to Change This World That Has Been Predetermined for a Long Time

God gave him the chance to be reborn and allowed him to travel through any space, but did not give him the ability to survive. Although he is lucky enough to meet the characters in the anime, when he gets tired of living, he will enter an alien space and fall asleep. Everything will return to zero. The people or things he knows will return to the original point in that moment, and that person will no longer exist in his life.
