Helen Miguel Diaz's twin sister ( moon x oc x valkyrea)

After Miguel and Helen come to the valley Helen decides when her brother joins cobra Kia that she will stay out of there because she knows the history of the dojo. But when Miagi-do opens she tries to learn the ways of karate all while failing in love worth two of the most popular, sweet and dreamy girls in the school will she get the girls of her dreams or will these girls ignore her and go after someone else ( valkyrea is younger it's like a high school au but she still has the same fame)
