Soon after, her new step dad gets transferred overseas and her mother follows him there, leaving Mitsuki alone with her new step brother, Yuuya.

Experience the robot maid occupation like you've never seen it before in Hinadori Girl. Support Robot: Sally 001 has just been completed by boy technophile Yoshiki.
