。An 18+ tactical role-playing game where you advance a mobile fortress and aim to conquer an "alien cave" that is said to be impregnable. The King and Nanas decide that something good must happen at the end of a mysterious cave called the ``Extraordinary Cave'' in the monster world that spreads to the northeast of the continent, and they want to take on the challenge. I kept thinking. However, there were some who wanted to know what lay beyond that and led their armies to rush forward, but the cave continued to consume them all. Then, Nanas finally invents a magic device that can summon strong people from another world, gathers all the characters from Alice World, and goes on an adventure to make his dream come true.
