A story where a low class girl named Claudia Aerith Dale Mendes, who works and studies hard to get a scholarship to the prestigious school of Silverbrook Academy, to find out what happened to her brother, Louise Adrian Dale Mendes who was a former student of the Silverbrook Academy who has been missing for 4 years.
The Silverbrook Academy is a school, a boarding school, where students are ranked by their intelligence and wealth , a school that has a special program called Class Alethean for specific students who are special, but she would soon regret this decision because the moment she sat down and took the exam to get the scholarship....would be the start of her endless nightmare.
