After playing and loving Kana: Little Sister, and getting used to and becoming emotionally attached to Kengo Yonekura's occasionally spotty artwork, well...this version of Kana is practically in the Uncanny Valley. I recognize all of it, every character and CG, but it just looks unsettlingly wrong.
Except Miki, she doesn't look like she changed. And I guess Yumi's redesign is okay.
