Naminé

Naminé is a character from the video games Kingdom Hearts: Chain of Memories and Kingdom Hearts II. Namine's name was modeled after Nami, a Japanese word meaning ocean wave, likely a reference to Kairi's name, which, when written a certain way in kanji, means ocean or sea.
A mysterious young girl, Namine has the ability to change memories by rearranging them and creating new links between them. Her ability derives from her unique birth. Because of her unusual powers, both DiZ, agents of the Organization and herself refer to Namine as a witch.
She was forced by Marluxia to rearrange Sora's memories after he loses them upon entering Castle Oblivion. Being passive and timid, she takes the abuse Marluxia and Larxene heap upon her. After meeting Sora, Namine appears to become less timid and afraid, seeming more willing to act upon what she believes is right.
Namine is voiced by Brittany Snow in the English version of Kingdom Hearts II and Iku Nakahara in the Japanese version.
Naminé and Roxas appear to be of a similar nature, not quite supposed to exist, yet still existing because of someone else. While Roxas is the Nobody of Sora, she is actually a "special Nobody" born from Kairi's heart when it left Sora's body. As Kairi had no darkness in her heart, her heart hid within Sora's body instead of becoming a Heartless when Destiny Islands was consumed by Darkness. When Sora impaled himself with the Dark Keyblade (in KH1) his body and soul were used in Naminé's creation (as well as Roxas's). As a result of this, she had none of Kairi's memories. Namine's special birth in conjunction with the fact that Kairi's heart had been in direct contact with Sora's is why, DiZ states, that Naminé's special powers could only affect the memories of Sora and those whose hearts are connected to his, which was why she was used by the Organization. DiZ had her protect Sora in his deep sleep while restoring Sora's memories, which affected Roxas.
Despite DiZ's orders, Naminé visits Roxas in Twilight Town. She appears to him several times, often before he is attacked by Nobodies, acting somewhat as a guide to him. It is Naminé who tells Roxas of his true nature as a Nobody. When he is told that he will disappear, Naminé quickly answers that "he'll be whole". As DiZ takes her away, she tells him that they will meet again, even if they do not recognize each other.
She is not seen again until near the end of the game. She frees Kairi and Pluto from imprisonment and they attempt to escape from the Organization's stronghold. They encounter Saïx, but, fortunately, are saved by Riku (in the guise of Xehanort's Heartless).
Naminé then gives up her own existence as an independent entity and fuses with Kairi to complete her, just as Roxas fuses with Sora. However, it is said in her and Roxas's conversation that they will not fade, but rather be whole and live on through Sora and Kairi, thus proving that not all Nobodies are destined to fade into darkness. This is further signified in the ending, as we see Roxas and Naminé one more time, smiling through their counterparts at each other when they return to the Islands complete, existing both as Sora and Kairi, but also as their own seperate entities.
