Classroom of the Elite 4th Season: Second Year, First Semester Episode 15

As Kiyotaka Ayanokouji and the rest of Class D enter their second year at Tokyo Metropolitan Advanced Nurturing High School, they are faced with a strange and unusual special test. The scenario involves each second-year student paired with a new first-year student and taking a written exam together. The test seems simple, but the catch is that if they don't reach a certain score together, they will be expelled from school. Now the entire Class D team is busy trying to find students who are sharp in their studies. Without a break, Class D sets out in search of partners, but a different kind of death is stalking Ayanokouji. His old enemy, the secret and dangerous "White Room" area, has sent a new, quiet and intelligent player to the school, who has only one goal: to destroy Ayanokouji at any cost. Now Ayanokouji must start his old, mind-boggling plan from the beginning to take out everyone, while protecting himself from both new and old enemies.
