Welcome to an unusual world where people are under a ghost’s authority. Hiiragi Akito is a sophomore at the Element Academy. He is a diligent student but fails every time he tries to sign a deal with spirits. Akito’s dad belonged to a spirit knight group, so the son dreams to achieve the same title. He falls into depression as his skills show the worst level at school. Hiiragi starts thinking that a bad result forced spirits to refuse him. The story retells about a guy who used all the methods to receive his goal, concluded a treaty with a sacred creature and ladies who were well in magic.
