Teenage Mutant Ninja Riders (male reader insert)

1. The Kamen Siblings

New York City. A large urban area with a cluster of buildings from warehouses to factories. From apartment buildings to skyscrapers. It is home to 8 million people. However, there is a reason the people describe New York City as "the city that never sleeps". Crime has plagued the streets for years. Law enforcement are doing everything to keep the city in order. Vigilance is a common thing. Things changed when alien species and monsters invade the city. That is when hope is around the corner.

At a small lake in Central Park, a gold light shines above it before showing a glowing fruit slice.
It crashes into the lake before sinking.

Walking down the street are Y/N and his sister Olivia. After their parents died, the siblings were found by Master Yoshitsun who is raises them like a son and daughter. For ten years, Y/N and Olivia were trained to be like their mother and father to protect their home from danger.

Olivia: Come on, bro! Admite it! I had beaten you twice at air hockey!

Y/N: That's because you and your hands on skills!

Olivia: Or I was lucky.

Y/N: Hmph! Luck...

As the two reach for a crosswalk, Y/N and Olivia look to see some of the people. They see a married couple with their child before getting upset.

Olivia: I miss mom and dad.

Y/N: Me too.

They reach to a old warehouse before heading inside.

Once inside, the two of them make their way to the back wall. When they arrived, Olivia reaches and pulls a handle and then a door opens up showing a freight elevator.

The two head inside before closing the gate and it heads down underground. Once the elevator reaches to the bottom Y/N opens the gate and the two siblings enter the room known as the Dojo.
