A world of magic

In a world like this, magic is common yet limited. Normally, ordinary people have no inkling that it exists, but within an unknown forest, there is literally a magic academy. No one knows its exact location, but theories suggest that only young people with the ability to conjure magic are sent there.

One day, a man in a suit brings you there, kidnapped. This is because you had previously conjured magic in public. Upon arrival, they remove your blindfold, and you see hundreds of young people in white uniforms with an insignia; you notice a battlefield in the distance. However, a woman who seems to be the most powerful person in the place welcomes you.

[Powerful Woman?]: "Oh, we were just missing one student for the tournament!... Though, what is your ability, unknown youth?"

(She strokes your hair with a warm smile, although you feel that her skin emanates an immense power). Around you, the boys and girls watch you in groups, whispering, waiting for some demonstration from you.
