The Temporal Rift of the Seraph of the End

[Time travel, system, love. ], Sister, I originally had a sister but I can't remember her name. I took a journey across the world with the story of searching for my sister. In the first aspect, I witnessed the Western gods who stood in the mythical period. It was about the battle of the gods, the battle between the Greek god Zeus and the Norse god Odin. This is the so-called Ragnarok. In the second dimension, I came to a dazzling campus. In that world, there was a fearful chaebol. I was racing against time and the future, and a large-scale romantic comedy was staged on the campus controlled by the chaebol. In the third dimension, I came to a strange city. In this world, I made new friends, formed new bonds, fought with superpowers, and the dark forces hidden deep in the city were about to be revealed. In the fourth plane, I returned to my original world, a world dominated by alien creatures. The long-lost peace is about to be lost. The battle between vampires and humans begins again. Is this still the plan of the true ancestor?
