Shirogane couldn't tell Ms. Herthaka that sometimes humans need to expose their weaknesses and endeavors to practice rapping which should be able to convey that. But his rapping skills are catastrophic. Fujiwara, who previously taught him singing and dancing, tags along for practice. But she's a total amateur when it comes to rap that she's on the level where she's convinced it's all simple-minded puns. So Fujiwara begins special training. With the advice from Shirogane who has overflowing knowledge on rap music, she rapidly improves... But something is still missing!
You were able to match him
on your first try! That's our Kaguya!
!تمكّنت من مجاراته في محاولتك الأولى! كما هو متوقع منك
Das ist unsere Kaguya-san, hört einmal zu
und kann schon mitmachen!
No mucha gente sería capaz
de rapear sobre la marcha.
No mucha gente sería capaz
de rapear sobre la marcha.
C’est tout toi, d’arriver à nous suivre
pour ton premier rap.
Grande! È la prima volta che lo vedi
 ma sei riuscita a stare al passo, brava Kaguya!
Conseguiu entrar no clima de primeira!
Impressionante, Kaguya!
Как всегда, с ходу поняла,
что к чему, Кагуя!
