School Transmigration: I, Chosen as the Saint by Dragons at the Start

Owen, an ordinary high school student, finds his life turned upside down when he and his classmates are unexpectedly transported to a fantastical world teeming with magic and strange creatures during a school event. In this new land, arcanergy flows through everything, and the ability to wield it determines one's status among the various noble races. While his peers quickly attract attention and are hailed as Saints, Owen remains overlooked and unnoticed. Just as hope begins to fade, a dramatic twist changes everything: the ancient Dragon race descends, choosing Owen as their Saint in an unprecedented ceremony.
