Kingdom Hearts: Dormant Memories is a fan web comic about Demyx and Nixsa.
Before Demyx and Nixsa became Nobodies, they were in love and lived together happily in their homeworld, Flore. But when they lost their world to the heartless, they got separated. Their hearts were lost which turned them into Nobodies. Demyx was the first to find and join the Organization and eventually so did Nixsa. Without a heart, Nixsa must understand her inner self to unlock the secrets of the heart.
This story takes place when Organization XIII only had 10 members, around a year or less before KH1. The 10th member is Nixsa.
