Seo Juhyun and Seo Jinhee are the beautiful daughters of Seo Minwoo, a farmer, who lives in a village near Two Moons Academy. Not many people knew of this but Seo Minwoo is the owner of two black diamonds. These black diamonds are the most powerful diamonds in the entire universe. Whoever has the black diamonds is able to be the most powerful person.

To keep these diamonds safe, Minwoo acquired the help of a shape-shifter to change its shape into bracelets which he gifted to his daughters for safe-keeping. Nobody knew about these diamonds except for the Principal and the shape-shifter who passed away 10 years ago. One day after school, the Principal had an ominous feeling. He closed his eyes shut and saw a vision. Principal Lee saw a dark figure going after the Black Diamonds and he knew that the Seo family will be facing some serious trouble.

Now that the Dark One is set to get his hands on the diamonds, the Principal is forced to send his most treasured students on a journey to keep the two sisters safe and away from the Dark One. What will happen to these 16 students of Two Moons Academy? Will they be able to fight against their enemies or will they be defeated?
