Soon, another school year had passed. Everyone else went home for the holidays, but Airi did not get to enjoy such leisure. In fact, her "superiors" had invited her to a secret military base, where she taught soldiers about magic.
From this alone, Airi could tell that they had clearly begun making plans. She was also curious about how much power modern technological civilization truly had against magic, so she was quite willing to cooperate with them in a series of experiments.
As for the results... they could be said to have been both good and bad.
According to Airi's findings, spells in the world of Harry Potter could generally be divided into two categories.

Their effects were clear and difficult to resist, but the problem was that their target lock and range were extremely limited. They generally affected only one target, and their range was not much farther than a handgun's.
