Shuusou Gyoku features one playable character with 3 different modes. Homing missile is good for beginners or people who are too lazy to move. Wide shot is also useful for less movement, and can clear a whole screen of enemies quickly. Laser is great for destroying a boss fast.

The game uses an Evade system to let the players rack up massive scores by constantly grazing. All enemies drop point/power items; their value increases based on the point system and how high you are on the screen when you collect them.

On Earth, the environment had nearly been destroyed, and humanity was on the verge of destruction. However, Kakutasu Company perfected an energy source more powerful than atomic energy. They used this power, known as Saboten energy, to stop the ruin of Earth. However, this energy was very unstable, and caused large accidents. Eventually, it was controlled, and humanity began to prosper once again.

VIVIT, a robot maid powered by Saboten energy, heads out to do errands for her master. As she leaves, various people fight her, for seemingly no reason. Milia randomly stops her, claiming vengeance for her men, which VIVIT has no clue about. After that, she fights Mei & Mai. After that, she find a huge energy signature, which happens to be Gates, a military veteran. He dares VIVIT to show him her true power, and she does so, defeating him. Then Marie fights her in a gigantic ship, and dares her to go on, for the true terror lies ahead.

However, she is stopped as she goes deeper by her own master. He explains that this errand is to save his daughter, and that her previous enemies were tests. His daughter was sealed in an accident, and VIVIT is the only one who can save her. In one final test, she defeats her master, and goes to save his daughter. As she finds his daughter, she is surprised to see she looks exactly like her. She is suffering, and after a difficult battle, VIVIT manages to save her, completing her master's dreams.
