檻姫～極嬢の未来は俺のモノ～

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. I pick up the remote control and turn on the TV. "Princess of the Kingdom of Lidomea, Emergency Visit" What was shown on TV was a beautiful woman with beautiful long hair, like silver thread. "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...
