Red Matter a physical digital code that corrupted both Shuuki and Humans alike. These new monsters known as Chimera and Aberrations wreaked havoc in both Mato and Earth.

Kirari Momobami Transmigrated on Classroom of the Elite After dying in her original world, Kirari Momobami awakens as a newborn in an unfamiliar reality. Retaining her memories and personality, she quickly realizes that this world operates under a rigid system that values logic, control, and measurable ability above all else. However, her unnatural disposition and unsettling behavior as a child lead to her being abandoned by her family at a young age. At just four years old, she is taken into the White Room-a secret institution designed to produce perfect humans through extreme education and psychological conditioning. There, she grows alongside other children of the fourth generation, including the boy who would later be known as the "Perfect Human," Kiyotaka Ayanokoji. Yet while others adapt to the system, she does not seek perfection. Instead, she embraces unpredictability, treating even the harsh environment of the White Room as a game. Years later, she is enrolled in Advanced Nurturing High School, where her presence begins to disrupt a system built entirely on logic-proving that not everything can be calculated. This is a chaotic scenario that would essentially turn the Advanced Nurturing High School (ANHS) into a playground of high-stakes psychological warfare. Kirari Momobami doesn't just play the game; she rewrites the rules to see how people crumble under pressure.
