Sakura Taisen 4 ~Koiseyo Otome~

Oogami Ichirou returns to Japan after having defeated the evil that threatened Paris. Something is once again wrong in the Imperial Capital, as two street cars go berserk without any reason, saved only by the mech-commanding girls of the Hanagumi Brigade. The girls from Paris Kagekidan return to join forces with the original cast, to help Oogami Ichirou to defeat evil one more time.
