About her: Yaya loves competition. That’s why every time her elite samurai tribe clashed with the ninja clan from the nearby kingdom, she was obsessed with coming out the victor. There was just one pesky ninja, named Mitsu, that always seemed to get the best of her. Yaya’s obsession with her soon turned into passion and she left her shogun to become a ronin and form a private agency for favors together with Mitsu. Now the two are partners in life, and only compete in the bedroom.
