On the park one night, I came across a battle unfolding between monsters and Magical Girls. Those girls happened to be my students, from St. Étoile Academy.

They said, "This world is being invaded by beings from another world, and so we're fighting to protect it" An absurd explanation, yet it was proven true by the conflict taking place in front of me.

I thought about what I could do for my students, and so I decided to stay together with them, however...
