Let's first look at the evaluation of Shinohara Girls…
Gintoki: Shinohara Akiko, she has straight hair [picking her nose] (Shinohara: How resentful are you for your natural curly hair? All the natural curly hair in the universe will cry, really)
Katsura: It's not the wig, it's Katsura (Shinohara: I didn't say wig, but Katsura. Hey, are you speechless? Are you really speechless?)
Takasugi: Akiko is very well-behaved and cute, which is much better than the natural curls who only compete for the teacher's favor (Shinohara: Very well-behaved and cute... Is that how you describe me? Voice-over: It should be very [beep-] and very [beep-] [beep-])
Shinpachi: Akiko made me discover the meaning of glasses (Shinohara: I'm just a cute guy with glasses like April 1st)
Kagura: A guy who doesn't know how to appreciate vinegar kombu (Shinohara: I'm not pregnant, so I don't eat sour food. I'm a pudding lover. If you have pudding, please give it to me. Thank you)
