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!
I only joined because Nagisa was in a bind,
and I thought I could help.
.انضممت فقط لأنّ ناغيسا كانت في مشكلة وفكّرت في مساعدتها
Ich bin beigetreten, schlicht um Nagisa
aus der Patsche zu helfen.
Me uní solo porque pensé
que la ayudaría.
Me he unido
solo porque pensé que la ayudaría.
Je me suis inscrite
parce qu’elle avait l’air bien embêtée.
Mi sono unita al suo club
 soltanto perché volevo davvero aiutarla.
Apenas entrei com o
puro desejo de ajudá-la.
А потому, что искренне 
хотела выручить подругу.
