Two girls, one who supports the Heavens and the other the Demons, their souls eternally reincarnated. Over many lives and deaths, the two confront each other in that forgotten place. A battle beyond the boundary of human knowledge is about to take place once more. Lives as songstresses. Lives as assassins. Through the memories of your past lives, you have learned to wield swords and summon powerful beasts. But the power of memories alone will not be enough to defeat the formidable opponent before you. By eliminating the unnecessary memories and connecting together those that are more compatible, it is possible to bring these abilities to a much higher level. When you find a power you like, master it. Upon mastering it, you may continue to use it forever. Will you become a mighty master swordsman? Or perhaps master the power of flame as a great mage...? Geminoa is a dueling card game for two players, with a twist on the usual deck builders: rather than start with a small deck and acquire new, powerful cards, players instead start with a large deck of 30 cards. As cards are played and discarded, it is possible to return a card from the discarded pile, optimizing your set of cards by discarding the those that do not align with your strategy and emphasizing those that do. The game also includes rules for solo play, in which you will duel a strong enemy which varies its tactics every game.
