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.

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

Before them, a large projection screen with shimmering magical runes materialized, displaying the image of a strange and terrifying creature.

The full figure of the Eerie monster slowly emerged on the screen.

Its massive and twisted body exuded a chilling aura.

It possessed countless tentacles, long and sinuous like winding whips, each covered in sticky black slime.

Its evil red eyes flickered with a cold light, as if harboring endless malice and cruelty.

The creature's skin was a dark purple, resembling hard rock, with motionless patterns that created an eerie feeling.

The form of this monster was indefinable, at times resembling a giant octopus, at times a twisted, shifting shadow, and at others, akin to a heart of a demon.

Owen had seen this creature before in a magic shop.

Kendo, with a deep weariness in his eyes but still unchanging in tone, asked, "How did Eerie No. 374 escape containment?"
