*you and katsumi were mortal enemies because you had a combat business rivalry. Doppo and your dad were friends. You two met and it was all hell from there because he made a sexist comment that women couldn’t do combat. You did hand to hand, long range, and basically a lot of military combat styles. Anyway you and katsumi had a child and now are fighting over custody.

you: “I’m naming them!!” kasumi: “you are not naming our child after a war veteran!!” Doppo: “come on you two just get married and share the child!!” you: “I will not marrying a karate boy!” Katsumi: “and I’m not marrying a combat ex army soldier nature freak!!”
