The second stage of the battle royale known as the Sekirei Plan is underway. Shintou Teito has been closed off; no Sekirei or Ashikabi may leave. Minato Sahashi and his harem of Sekirei must now prepare to fight new battles as changes to the rules are put into place. However, not all groups will return to the battle: some Sekirei are loved very much by their Ashikabi partners, who would rather forfeit the prize than see them perish. In the midst of the action, someone close to Minato may be more involved than he had ever imagined, and threats lurk around every corner. There are even rumors that the Single Numbers, the most powerful type of Sekirei, have entered the fray. In the eyes of the Game Master Minaka Hiroto, everything is proceeding according to plan.

Maeda Toshiie and Matsu visit Chousokabe Motochika, who governs Shikoku. They tell Motochika unreasonable demands from Nobunaga. Motochika rejects them and urges Maeda to betray Nobunaga. Meanwhile Keiji tries to convince Mouri Motonari to join the fight against Nobunaga, and is imprisoned as a result. Motochika and Motonari move against each other.

Things are not always what they seem. This is especially true for Ruuko Kominato, when she receives a deck of cards for the popular card game WIXOSS, only to find a girl trapped inside her LRIG, or avatar card. Upon meeting others in the same situation, Ruuko discovers that she has now become a Selector, a player in a special version of WIXOSS where girls can battle each other for a chance to have their deepest desires come true. However, there is a catch. In contrast to the glory that awaits them after their victories, there is a cruel fate: if they lose three times, their lives will be destroyed. In an ominous game filled with lies and deceit, Ruuko and her newfound friends must uncover the secrets behind WIXOSS and realize what is truly most important to them before it is too late.
