In a world where your destiny is sealed by the “Job” granted to you by the Goddess, Arius was saddled with the dud job “Title Master” and branded as “useless” by his guild leader, Rebra, before being unceremoniously kicked out. With nowhere left to go, he meets a winged girl named Ria in ancient ruins, who claims to be a goddess herself. The instant he follows her advice and bestows a title upon himself, an off-the-charts power awakens. It turns out “Title Master” is an all-powerful cheat job that can freely debuff enemies and unlock the true potential of his allies. Now, he rises up to save his ailing sister and face what lies ahead. An exhilarating zero-to-hero fantasy epic begins now.
