Septuplets

From Samurai Jack, Ashi and her sisters as modern girls. In this life, their mother is a ruthless, deputy president of a company rival to one owned by Jack's parents. Because of that, their mother doesn't approve of her daughter (Ashi) having feelings for the son of her boss's rival. Also, her boss is Aku, whom she admires greatly for trusting her to be his right hand woman. Nor for the daughters. I don't know the order in which they were born so I've made it up:

Ali (oldest): A cheerleader who bosses her sisters for their own "protection".
Aki: A flashy performer who learned acrobatics to achieve her dream of joining Cirque du Soleil.
Ani: Fashionista of the family.
Ari: Tomboy and everybody's friend.
Ami: the tsundere punk girl
Avi: the bubbly optimist
Ashi (youngest): the shy introvert and the most obedient of their mother.
