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!
