Owen, an ordinary high school student at Saint Aya Academy, finds himself and his classmates mysteriously transported to a world filled with magic and bizarre creatures during a school event. 
In this world, arcanergy saturates the land, and all intelligent beings can harness it. 
The more adept one is at utilizing arcanergy, the more noble their race is considered.
Upon arriving on this new continent, the students from Saint Aya Academy immediately attract the attention of various powers. 
They are referred to as Saints and are chosen by powerful races to be groomed as successors.
However, Owen seems to be as inconspicuous here as he was at school, with no races showing interest in him. 
Even as his classmates find their places, no one extends an olive branch to Owen. 
Just when everyone thinks he will be left behind, a dragon's roar echoes across the sky.
The ancient and mighty Dragon race, in an unprecedented gesture of high ceremony, has the twelve Great Dragon Elders personally welcome Owen, choosing him as the "Saint of the Dragons." 
As everyone is stunned by this dramatic turn of events, Owen hears a "ding" sound beside his ear...

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

After Owen left, the lord turned to Kistan.

"Today, Ironblade City stands like a nail driven into the demon army's path. They must capture Ironblade City to advance northward. Our city walls are formidable, and our supplies abundant. Though our forces are significantly outnumbered by the demon army, holding out for some time is still within our capabilities."

"Moreover, the distress messages we've sent should have already been received by the empire's high command by now."

Looking towards the north, Dawson continued, "General will surely gather a large army and come to our aid in the shortest time possible. Hence, if we can withstand until the arrival of the reinforcements, by then the demon army's vigor will have been dampened. With a pincer attack from both inside and outside the city, we will surely defeat them at our walls."
