Reincarnated As A Demon

The Land of Haria is where the humans with magical powers live. The King suddenly receives a prophecy that Demon Kingdom will invade their Land. To prevent that, the King order his people to be trained to become Demon Hunters. Not so long after he told the prophecy, Demons came out from there Kingdom and started wandering in their land and kill people. Demon Hunters put their lives on the line to protect the people.
