Naminé is the Nobody of Kairi, and wields the power to manipulate the memories of Sora and those close to him. Her first appearance is in Kingdom Hearts: Chain of Memories. She also plays a minor role in Kingdom Hearts II. Naminé was born when Sora stabbed himself with Ansem's artificial Keyblade in order to return Kairi's heart to her body. This made Naminé a very odd Nobody, born from Kairi's heart and Sora's body and soul. Kairi's own body never became a Nobody because her heart lacked darkness (since she was one of the Princesses of Heart), so her body and soul were never able to leave the Realm of Light and thus made it seem like Kairi was in a comatose state until she regained her heart. However, this means that Naminé was also born without Kairi's memories, only furthering her status as an unusual entity. Yet she and Kairi are incomplete without each other, similar to Sora and Roxas. Due to the fact that Naminé is formed from Sora's body, she has the power to manipulate his memories as well as the memories of those who are connected to him, prompting several others, even herself, to call her a "witch".Ansem the Wise stated in his ninth Secret Ansem Report that Naminé is a highly unusual Nobody, due to possessing neither the body nor the memories that a Nobody is usually made from.
The first part of her name, nami means "ocean wave" in Japanese, similar to Kairi's name, which is derived from the word for "sea". Her name can also be translated to "sound of the wave" in Japanese, since the character 音 (oto) can be pronounced as "ne". Alternatively, her name can mean "born from the wave", because of the French "né" at the end of her name ("né" is the past participle of the verb "naître", which means "to be born") as a reference to her birth from Kairi and Sora, as a wave can come from air and sea. However, this may have just been added in the English releases to ensure that her name was pronounced the same way it was intended in the Japanese original.
