"There is a golden dragon that lives in the Silver Star Academy, which will grant all of your wishes."
The protagonist Yume had enrolled into the prestigious academy of magic, "Silver Star Academy". However, her entrance was only accepted due to "luck", having been randomly selected to fill in a spare spot. As a result, she couldn't keep up with the high levels of everyone around her. But Yume had a wish she desperately wanted granted.
"Where is my real father and mother?"
Back on her fourteenth birthday, she found out from her "mother" that they weren't blood-related and that's when she had decided she wanted to know her roots.
"I just want to know and that's it... because my family is mom and Akito."
However, as Yume was raring to seek out the dragon and get her wish granted, her non-blood related brother Akito had a secret wish of his own. Unlike Yume, Akito was a genius magician to the point of being called a prodigy and enrolls into the academy as one of its top entrants. Yume suggested that the two work hard together as siblings to search for the dragon but Akito had replied in irritation:
"I haven't thought of someone like you as family since ages ago."
Though Yume was shocked, the true intentions behind Akito's words weren't what they literally seemed to convey. The Academy was filled with boys and girls from all around the world that bore secret wishes and were also seeking out the dragon.
