I Became the Strongest Devil High School Student

“Humans stand on the line between good and evil.”
A normal high school student.
Because of a small reason, he was killed by bullies.
But death was not the end.
He made a contract with a fallen angel.
And gained the power to go back in time in real-time.
From that day on, he makes choices every moment—and turns back every moment.
A boy who slowly erases the line of good and becomes filled with evil.
Now, the return of an ordinary high school student—once just a nobody—into evil begins!
