Shoukan Juushi no Gakkou

Long, long ago, there once was a country inhabited by summoned beasts. However, that country is no more and they now live scattered through various parts of the world. It has been 100 years since a school was created where summoned beasts are taken in and used to help foster a child's growth.
Cora was born and raised in a town that discriminates against those beasts. However, one day, she befriends a boy named Kilian who is confined in a dungeon.
Escaping the town where summoned beasts are oppressed, she leaves home and heads towards a school for summoners.
