Wonderful Twin World is a continuation of "Heart no Kuni no Alice", and its fandisc.

A whirlwind comes to Wonderland. Then, Wonderland goes crazy. Tweedle Dee and Dum are gone,Vivaldi has a crush on Peter, Blood likes Coffee, and Ace has a sense of direction! On top of that, two new roleholders have appeared, Humpty and Dumpty. This game is based on the premise that Alice fell in love (or in Vivaldi’s case, found a deep and meaningful friendship) and decided to settle down in the first Heart no Kuni game. An indeterminable amount of time passes after the first game and a new phenomenon is bearing down on the residents of the Country of Hearts. The Crazy Storm will change something about each and every one of the residents, including the people whom Alice loves. Even before the storm arrives, Alice finds that she has no memory of two of the residents of the Hatter Mansion, Humpty and Dumpty. Meanwhile, Alice dreams about two mysterious eggs who urge Alice to become their king and hatch them.
