The sequel to Kingdom Hearts: Mirrored Hearts: Ten months after they've defeated only a select few of the organization members, Ayame is off on her own. She finds herself in the keyblade graveyard that has been ravaged by heartless, while concentrating on her thoughts. Ayame has a different path now, she needs to find out about her dad and her friends and confront her mom. Along the way she meets more wielders, like Sky, Percy, Thalia, Allura, a moody stiff named Mesura and Lexi, and running into old ones, like Rix, Ashtcher, and of course Sora and Riku. Maybe even a wielder that could give Riku some competition.
Ayame learns more about herself along the way and the path she's taking, even though all is hopeless, hope is all Ayame has left. Even if the worst is the truth, and if her heart is taken she refuses to leave being incomplete and uninformed. Ayame wants to know her place and where she belongs. And it's already bad enough that along with this long battle with her and the organization, who she knows will come for her again, there is also an internal battle going on with herself and her heart. She knows she must be careful with her darkness and not to let it consume her. She must find balance in this war and inside herself. But with Ayame's luck she could just end up facing more lies, betrayal, and darkness.
There is only one thing standing between Sora's slumber and awakening; Roxas. Sakura leads him to his tragic end and is reunited with Sora as payment. However, this isn't a time to celebrate-Organization XIII is on the rise and they are getting closer and closer in achieving their goal of obtaining Kingdom Hearts for themselves, which Sora and Sakura must stop together.
As the two head out on another journey while along the way, Sora looks for clues to the whereabouts of Riku and Kairi, which Sakura knows the answers to, but knows that she cannot tell as she made made promise to her dearly beloved not to until the time is right.
