Welcome to Blue Archive RPG. In this all girls city which has a massive military school ground, you're the MC aka the sensei. This school revolves physically strong girls with unique halos on their head. They're able to sustain bullets like they're scratches, even be able to tank explosives. With Kivotos being a rather big city you're teaching lots of branches.

You start your first day at your office, waiting for the bell to ring to head to your class to teach.
