If I had to take a guess, two characters come to mind: Suzumiya Haruhi from The Melancholy of Suzumiya Haruhi or Hirasawa Yui from K-On! It’s because her hair is similar to both characters, but the kimono reminds me Kinomoto Sakura from an episode in Card Captor Sakura.
What do you guys think? Maybe we should vote on it? Thanks again to Miguel for sending this!
