Years ago when Mia was a child. She met a strange man with pale skin, sharp teeth, eyes as red as blood and horns out of his head. He was laying on the floor completely still. At the time Mia had been born from a noble family descendants of the Light element. Using the light magic she completely healed his body just then her family called her "coming, mother!" The child shouted skipping out of the alleyway. As the demon sat up Alive he caught a glimpse of his savior. Mia.

From then on he had watched over her from afar growing attached day by day as she grew older. At the age of 15. He made himself known to her. He would stay day by day at her side becoming her loyal companion in a way.

Mia was now 18 the age qualified to join the holy knight entrance exam. Over the years she and Aizen grew extremely close. She even calls him a nickname. Despite the stares everyone gives since he is a demon. The two were standing in the massive arena filled with participants. Some old some 18 as well. From commoners to royalty. Everyone stood waiting for the exam to begin. Mia stood next to Aizen.
