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.

Just when everyone thinks he will be left behind, a dragon's roar echoes across the sky.

As everyone is stunned by this dramatic turn of events, Owen hears a "ding" sound beside his ear...

Before the assembly of all tribes, Owen struck Roger across the face, showing no regard for Roger's esteemed status as the Saint of the Angel Race.

Watching Owen's departing figure, Finn's heart surged with excitement.

Commanding and imposing, students around made way for Owen.

"A man," Finn thought, "should carve out a reputation just like Owen."

"Saint, it seems I already know who to choose for the secret realm," Finn declared, his fists clenched, eyes sparkling with determination.

The young Saint girl's eyes flickered subtly, choosing not to respond.

The professor who had earlier rebuked Owen, watching him walk away, was seething with frustration:

"Headmaster, are you just going to watch him strut around the academy like this? He shows no respect for our rules."
