200X years. One of Japan's leading entertainment districts - "Sakae Town". It's a red-light district for men and women of all ages, both now and in the past.

"A party to welcome you to Japan will be held somewhere in Tokyo in the near future." A normal woman wasn't enough, but ... a princess? I've never been with such a noble woman...
