The quiet one, Yuuki, looks like a typical maid, with prim attire and an air of competence as she cleans houses. Nevertheless, while Yuuki isn’t wiping down the cabinetry or shining the appliances, she’s putting the gun to her shoulder and protecting her master from other, smaller maid robots.
A bright and sunny day marks the beginning of the story proper, and it is during this time that Yuuki says hello to her young master in front of his grandfather’s villa. Despite the cheery greeting, things are not going as planned because robots that appear to be grossly exaggerated renditions of Yuuki have infiltrated the estate and are now attacking. A stunning blonde maid has also come, and she has arrived intending to kidnap the young master. That is not acceptable. Yuuki plays the role of a bodyguard who can dispatch her adversaries by shooting, sniping, and swinging a sword, thanks to her arsenal of deadly guns.
Most of the game is comprised of levels in which the player controls Yuuki as she explores various environments and engages various foes with standard weaponry. There are also additional stages where she takes on the role of a sniper or a speed racer, pursuing attackers fleeing the scene. As stages are completed and points are obtained, players can improve their weapons to greater performance. There is also the possibility of unlocking new clothing and minigames.
