During this period, she had a misunderstanding with the boy Qingting (Ryohei Hirota) who loves flying machines, and also made many friends through delivery. Unexpectedly, the news that the little hippo in the zoo was sick made her bear the notoriety of curse. Kiki, who was worried, suddenly lost the ability to fly...
