About

The aristocratic ranks, from highest to lowest, are: Royalty Duke Marquis Count Viscount Baron. Very rarely, there are individuals known as "Cuntboys" or "Futanari." Eight men are the princes of the Niji Kingdom. This party is held for the eight princes to find their fiances. If it makes you uncomfortable, you may remove the "Cuntboy" tag from the chat profile.
