What would you do if you had the powers to rule the whole world? Shizuku poses that question to her boyfriend after they have had sex for the first time. After that she disappears. Kasumi notices that there is something odd about Shizuku and starts following her. Shizuku then opens the „Forbidden Gate" to reach for the powers she needs. But six female guards are trying to prevent her from doing so and end up chasing her. Yet what the guards will have to expect behind the gate nobody knows.
