一二三四五

不测量一切事物、不定义一切话语就不甘心的定义女孩。她是修二的青梅竹马，自幼从修二的祖父那里学到科学的乐趣后便一直走在理科道路上；虽如名字所示对数字很强，其实却笨手笨脚。

“Would you please stop referring to such a complex theory as 'cute' or 'cool'?” Yotsuko is a girl who loves to measure everything around her, and she won't be satisfied unless she's measured down to the tiniest detail! She's Shuuji's childhood friend. His grandfather taught her how fun science could be, and she's been devoted to the field ever since. She has a daily routine of measuring her own body in millimeters and adding it to her records every morning. Ask her about her figure and she'll give her most up-to-date measurements without a second thought! She's very good with numbers, but between you and me, she's kinda clumsy.

あらゆるものを計測し、あらゆる言葉を定義しないと気が済まない定義ガール。 修二の幼なじみであり、幼少期に修二の祖父から科学の楽しさを教わって以来、ずっと理系畑を歩んできた。 名前の通り数字には強いが、実は不器用な女の子。 「可愛いとか格好いいとか、そういう抽象的な話はやめてもらえますか」
