Synopsis

The "Anti Foreign Dangerous Species Knights" was formed to protect the people from dangerous monsters, however this is more of a black company and it's only a knight order in name only...! Orcs that keep coming like pests no matter how many times they are taken down... salaries that don't increase at all... quirky co-workers... This is the story of the strongest swordsman of a commoner background, who works hard everyday cutting orc's heads in the lowest knight order which is ridiculed as "Pig Hunters."
