Great! Picture this: A teenage female oc is the daughter of Murakami, born in Japan until they moved to New York after her mother dies of illness when she was nine years old. The female oc helps her father run her family restaurant, but sometimes at night when they closed, she has a secret: Her ancestors were samurai warriors, like her mother when she retired and her grandfather before he died, and was trained in the arts of a samurai by her grandfather since she was little in Japan. After they moved, Murakami's daughter trained herself as a samurai to make her mother proud regain her ancestors' honor, WITHOUT letting her father know.
Suddenly, when the purple dragons attacked, Murakami and his daughter were met by four teenage kappa turtles. Now Murakami's daughter has begun her journey as the Mysterious Samurai as she joined her kappa friends on their adventures while keeping her identity a secret, also falling in love with a certain blue-masked leader. (When I said Mysterious Samurai, I mean she is very silent as well.)
It’s similar to Ninjago when Nya is the mysterious samurai, only without a voice modulator. What do you think?
