I just found a wonderful Anime [url=https://en.wikipedia.org/wiki/Castle_Town_Dandelion]Jōkamachi no Danderaion[/url] or in English "Castle Town Dandelion"

The story revolves around the Sakurada family, a family of nine super-powered siblings whose father is the king of an entire country. It focuses on Akane, the fourth-eldest child, who is extremely shy. However, the actions of her and her siblings are constantly being recorded and broadcast on TV, allowing the citizens to choose which one to elect as the next king.

Heck it almost looks like it would be fun as an RP
