Tatsumi's young sister Kasumi comes over to visit, and he fails to hide Wakasa from her. Kasumi initially assumes that he is her brother's human girlfriend here to take him away from her, but Tatsumi and Wakasa explain the truth to her. Tatsumi gets Kasumi's word of honor that she will not tell other people about Wakasa by promising that he will do whatever she says during her next visit. During the credits, Wakasa and Mr. Duckie see Kasumi sniffing her brother's clothes.
