When her hotel suite is bombed, the Sisters volunteer to shield her. After spending the night at the Paper Sisters' apartment, where she meets Anita, a jealous rival seizes Nenene hostage at the signing, but the three sisters foil the attempt.

On her way home to Japan, another rival attacks her, and the Sisters pursue and rescue her.
