Noah Elísio, a 17-year-old youth, is suddenly summoned to a battlefield by a cruel goddess, Freya, along with his classmates. Despising both the goddess and his classmates, Noah hesitates to cross a portal that would take him back to Earth, leaving behind his previous life without regrets. However, upon emerging from the portal, Noah finds himself trapped in a mysterious Dungeon, sealed by Freya as punishment for resisting her influence. Determined to escape, he discovers that he possesses a special ability called "Divine Eyes," which grants him unlimited knowledge and the ability to create auxiliary abilities as needed. Using his newly discovered abilities, Noah explores the Dungeon in search of an exit. He encounters a dark and hostile environment, filled with dangers such as corpses, remnants of past battles, and sinister creatures. Determined to survive, he fervently fights for his life.
