Mako
The self-styled "former idol," Mako is Hideki's 19 year-old cousin who is originally from Okayama prefecture and still has the distinct Okayama dialect of Japanese (portrayed as a Southern American English in the English dub). She is skillfully able to spend her older cousin's money on her lavish "Dom Perignon" tastes, but often deflects his marriage proposals by saying "the Japanese constitution does not allow it!," despite the fact that it does. She's attracted to Ichiro even though he does not return her affections and fights over him with Yukika. (Source: Wikipedia)
