He strongest knight works hard on the lowest knight order ~ Hunt the orcs until the end of earth that’s easy~

The "Royal 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 swordman of a commoner background, who works hard everyday cutting orc's heads at the lowest knight order which is ridiculed as the "Pig Hunters".
