This is actually an idea for a kingdom. So, introducing Theros.

The people of Theros are terrified of grimm, seeing them as demons. The only people that aren't terrified are the leader of Theros, and the hunters. The hunters of Theros are more skilled than those of the other kingdoms, due to having trained their whole life to be hunters. As for the academy, Safeguard Academy, the academy looks like an combination of a colloseum and an ancient greek temple. The buildings of Theros look similar to those of ancient Greece. Now, for the leader of Theros.

Her clothes are mostly blue and she is dark skinned with green hair and blue eyes. She doesn't bother with the politics of the other kingdoms and rarely contacts them, leading to most people not even knowing Theros exists.
Finally, the hunters of Safeguard Academy. This is the emblem of the school.

Now, the students are sorted by skill, so you have A-Team, B-Team, C-Team and the weakest, D-Team. These are the hunters of A-Team.
