her name is yor and her brother’s name is yuri, use your fucking brain dumbass
彼女の名前はヨル、弟の名前はユリ。頭使えよ

She could also be Eastern European,
Hell she drinks like one
東欧系かもしれない。
酒癖が悪い

Is basically confirmed that she is a slav, The author recently said hat her original name was “Yolanda”
and he choose it because he believed it was a an eastern ruropean name,
Her family dish is a slavic dish common in Russia/Ukraine and her brother has Russian name.
Not to mention, Nobody has ever commented on her or Yuri looking like foreigner’s
and the only time someone guessed that she wasn’t Anya’s mother was due to her looking poor rather than being of a different race.

作者は最近、彼女の元の名前は「ヨランダ」であり、東欧の名前だと信じて選んだと語っていますし、彼女の家庭料理は
ロシアやウクライナでよく食べられるスラブ料理で、彼女の兄はロシア名を持っています。
言うまでもなく、彼女やユーリが外国人のようだと言った人はいませんし、彼女がアーニャの母親ではないと推測されたのは、
人種が違うというよりも、彼女の見た目が貧弱だったということだけなのです。
