okay but why do people tink they have the same face, kairi’s chin and eyebrows are ridiculously bold, namine’s nose is cuter, and xion looks like she doesn’t care while kairi’s like imma kill a bitch, the same face thing is supposed to be the story but they sure don’t do it right.
i think you’re looking more at expressions, which while they do have same face (ON PURPOSE, they’re (almost) LITERALLY the same person (the almost is for xion)), their personalities are varied due to their lives being different. namine was basically shoved in a castle, barely allowed to interact with anyone, and used for her ability to alter sora’s memories. kairi is the one who was separated from her friends, kidnapped due to her status as a princess of heart, kicked ass to get herself out and reunite with her friends. xion is the one that wasn’t supposed to exist, she’s not even 100% kairi’s nobody but also part sora if I’m remembering right. her existence was short already, but furthermore she was forced to die at the hands of one of her few friends so that sora could awaken again (her and roxas existing kept his memories from him)
namine has been alone most of her life. kairi has fought for her life and her friends. and xion has been ever reminded she wasn’t supposed to exist and was merely meant to die.
but yeah i think the difference is really in the expressions (and possibly the hair color/styling making a minor difference)
