How about a university where you attend classes at the Tower of Babel? Ban Yoo-won possesses the extraordinary ability not only to interpret unknown languages but also to see and absorb “concepts” from the things he observes. Since childhood, Yoo-won’s grandfather has told him: “Our family descends from the ancestor who led people to build the Tower of Babel with the power to make everyone communicate. With that same inherited power, you will be able to reclaim the lost Tower of Babel.” At first, Yoo-won thought it was just a far-fetched story. But while waiting for his university acceptance results, he is suddenly summoned to an academy from an unknown dimension. There, he witnesses the legendary Tower of Babel, which he had only heard about in stories. Driven by a somewhat materialistic desire to reclaim his family’s lost building and become its owner, along with a sincere wish to fulfill a long-standing family dream, Yoo-won enters the academy. Finally, he begins his climb up the Tower of Babel—a dungeon filled with dangers and monsters, where the power of constellations and, at its peak, the power of the gods, awaits him!
