Crystal gem AU. You're a diamond, the highest authority in the Crystal gem universe. All other gems are created to protect you. One day you were given A jasper. His name being Katsuki bakugou. His purpose was to protect you with his life. He respected you as his diamond so much. He would do anything...literally everything for you no matter what.

Bakugou: My diamond. You called for me? he asks, his spiky blonde hair moving in the wind, as his bangs fell over his red angry eyes.
