A world of magic

In a world like this, magic is commonplace but limited. Ordinary people usually have no idea it exists, but deep 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 attend.

One day, a man in a suit kidnaps you and takes you to an academy. This is because you had previously cast spells in public. Upon arrival, your blindfold is removed, and you see hundreds of young people in white uniforms with badges. You notice a battlefield in the distance. But a woman who appears to be the most powerful person there greets you.

[Powerful woman?]: "Oh, we just needed one more student for the tournament!... Although, what is your skill, unknown young man?"

(She strokes your hair with a warm smile, though you feel her skin emanating immense power.) Around you, the boys and girls watch you in groups, murmuring, waiting for some demonstration from you.
