As a kid, you always wanted to be a ninja. No, not a villain or a hero. A ninja, who would be by both of the sides. After a few years of trying gymnastics, and other moves like a ninja, you became one while running away from your home.

You were walking on rooftops, while you saw the class 1A train. You sat on one of the rooftops, while you watched them. After some time you noticed that league of Villains was there too... they were about to attack them...
