Savior of the everyday world of crossover anime

Having transmigrated into the body of a wealthy heir and enrolled in Shuchi Academy, Takahashi Yu thought she would live a peaceful life.
As a result, the user is bound to the [Dimensional Clone Role-Playing System], which grants them the ability to travel through worlds and manifest as clones by acquiring role-playing cards, thereby increasing their role-playing ability and becoming stronger.
Absolute loyalty, fearless of death!
They were also told that various disasters would continue to occur in the future, and that the world would perish within a few years.
To save the world, Takahashi Yu can only grow stronger with the help of the system while simultaneously building his own power...
"Have you heard? Recently, it seems that all those important figures want to send their children to a place called Academy City."
"It is said that they also strongly support an organization called Destiny."
"Hey, did you hear about the gas explosion near Dongdu Bay last night? Apparently, someone took a picture of an angel at the scene!"
"How could that be? It must be a lie!"
Shuchiin Student Council, Takahashi Yu looks out the window at the students discussing.
On the surface, he is the student council president of Shuchi High School, the young master of the Takahashi Group, and a well-known model student, but secretly...
President of the Academy City Council, Founder of St. Freya Academy, Director of the Anomalous Item Containment Center, Stand User, One God, Partner of Justice…
I don't know why, but as the savior, I always feel like I'm getting closer to the mastermind behind the scenes.
