"Wind-up doll" Nano tries to cure the strong-willed 8-year-old Hakase's cold, but even the talking cat Sakamoto-san has difficulty getting Hakase to take her medicine. Yuuko, Mio, and Mai get into some mild mischief on an empty train. — written by foo2 Note: Originally bundled with the limited edition of the sixth manga volume.
