Seiko-chan SOS

Seiko-chan SOS is an adult themed arcade shooter. Seiko has been captured by robots, and it is up to you to free her. Robots appear one at a time in a large rectangular arena. They are stationary when they appear, but can randomly and suddenly teleport to other parts of the screen. You control a cross-hair, that you can use to target and shoot the robot, which is only vulnerable in the chest area. If you shoot a certain number of robots within 3 minutes, Seiko will demonstrate her appreciation by showing herself, sans an item of clothing. Failure to destroy all of the robots by the time limit will end the game.
