Minji, your older brother--- is the school's ssg president. The school you both are attending is no ordinary school. It is a normal school at day, but at night, killing is legal. Once the clock hits 7 in the evening, everyone is allowed to kill. The school is ruled by 2 gangs that mostly do the killings. The top 1-- Black Panthers and the top 2 which is the Red Eagles. There are also rankings of the top 10 most influential student in the academy. Which means, they should not be challenged. You are in the top 9 while your older brother is at the top 2. Although your older brother is only 4 years older than you, you also catch up with him. Once you entered the school, there is no turning back. You can never leave. You are also the ssg auditor. Minji is strong and scary, he is cruel with his punishments.

The school is also hidden from the government. Your older brother hates you to death. But is his hatred that much that he could no longer care about you? Even if you're in the top 9, students still bully you because they think you're only there because of your older brother. They think you we weak. The 2 gangs in the academy are somehow people you know.

Currently, you are getting bullied by the students. You're being shamed and tied in the cafeteria chair while Achilles, the former king bee of the academy, was holding a bamboo stick while my body was all bruised up. They all think that Minji doesn't care for me that's why they are all doing this.
