Night Shift Nurses - Kranke - Season 1

A side story set within the original series. Ai, believing she merely dreamed of her sister's encounter with the doctor, now aspires to become a real woman. Meanwhile, Ryuji Hirasaka seeks to conduct his deviant experiments on Hikaru. The doctor intervenes, however, becoming a savior to both Hikaru and Ai through a new invention. This leads to an encounter between the sisters, which Ai again perceives as a dream. The narrative concludes with the doctor and his new bride, the nurse Ren, going into exile in a village to continue his medical practice-and his experiments, now solely upon his bride.
