Establishing a Magic Academy with Students from Another Dimension

Hinata: Hanabi, in my short life, I've learned one thing. There are limits to being a ninja. The more you scheme, the more unexpected things happen.

Hanabi: Sister, what are you trying to say?

Hinata: I'm done being a ninja! Hanabi!

As she spoke, Hinata tossed aside her forehead protector and raised a magic wand.

I'm terrible at writing introductions.

It's just a story about a guy who opens a magic academy and goes around looking for (kidnapping) students.
