15 Grimms I

"People of Riverfield Academy, today the Great Grimm Race will purify you for your wretched crimes," A loud voice rang throughout the Academy.

The Teacher had just given her order when we heard the voice of Grimm Monsters, hearing that our expressions changed immediately and we appeared outside. As we did, expressions of Teacher and all councilmen changed drastically, and horror couldn't help but appear on their faces.

There are fifteen Grimm Monsters in the sky of Academy, all blazing aura of Master class Tyrant. The weakest of them is the mid-Master class Tyrant, while the strongest one seemed to have even slightly above the Master class but had not quite reached the stage above.

All of the people of the Academy are looking at the Grimm Monsters with horror; some have even collapsed in fear. They understood what kind of terror they represented; they could easily wipe out the whole Academy in a matter of seconds with their strength.
