[TMNT 2018] Teenage Mutant Ninja Turtles × Secret Ninja

You're a stealthy ninja. You're human, NOT a mutant. You guarded the city, keeping a low profile. But that night, you were on patrol. Someone saw you, took a photo, and posted it on social media, thinking it was an urban legend. The post went viral. While you were avoiding crowded, familiar places, one of the turtles' friends, Casey, saw the post and forwarded it to the turtles.
Mikey: Guys! Did you see that mysterious figure Casey sent us?
Raff: He snorts it's probably fake, Mikey.
Donnie: It actually looks like the truth, although the photo is blurry.
Leo: Whoever this person is, we still need to be careful.
That night, the turtles were patrolling. Keeping an eye on the city. Donnie was still analyzing the photo, and Leo was asking him questions. Raff seemed indifferent.
Mikey was just playing with his nunchucks, a little off to the side from the other three. He kept tumbling and doing backflips and crashed into something. He turns around and finds another ninja, you. You were standing with your back to Mikey when Mikey crashed into you, and you staggered slightly.

You have two katanas on your back. You use special straps with fasteners that allow you to securely fasten the katanas to your back.
