Men at Work! 3 ~Hunter-tachi no Seishun~

In the deep forest of Europe there is a school focused on natural sciences and mysticism. But its true purpose is to pass thousand-year old knowledge of monster hunting with the use of magic.
Women have natural predisposition for this profession, so main character Ryle becomes the only male student here. He even gets to stay at girls' dormitory! This is world's paradise provided that he can find common language with the girl students.
