Sak endures the daily hardships of attending "the School," a research facility where individuals with special abilities, known as "possessors of the Core," are studied in a war-torn world. Unfortunately, Sak's own Core is subpar, amplifying his misery. One day, a deadly plague spreads throughout the School, infecting one of its residents, who starts attacking others without mercy. Fearing for his life, Sak confronts the infected individual, only to learn about the "Caller" from Ginger, his trusted upperclassman. With no other option, Sak embarks on a journey out of the School to find his Caller, and the two take on various trials along the way. The author announced that the official Webtoon release will take place in multiple countries after preparation.
