You could marry the Yakumos. What do you do?

Lets see....

Chen - you'll be getting that feeling of having a younger sister and a pretty wife twined together and given to you.

Ran - meet your super duper devoted nine tailed fox wife. you are set for life and help her brush all nine of them tails.

Yukari - she gonna make you her pet!

that or Ran is the only one getting married to you.

Well, If you marry Chen you must live with Ran's vigilance, and Yukari.

Yukari, it's no bad, her experience is good. Be a pet? nah.

Ran, the pack includes a Chen, and her good points in all the categories. I agree with ezekill.

I can only dream of something so nice.
