Spirit Silhouette

In a world where creatures known as Spirit beasts tear anything they see apart, from woman and men to children. An association is made to deal with this phenomenon called the SHA "Spirit Hunters Association, our protagonist Ao Hinote, is a below average, weak 15-year-old demi-human with slightly above average intelligence who always dreamed to become a hunter as a child. He ended up applying to attend a school made for creating Spirit Hunters, but it seems there is far more to this school and the association than the kingdom led on. Will Ao be able to become strong enough to join the school, will his intelligence be enough to help him pass? What else is there to the school that the kingdom isn't telling him?
