Saikyou Kishi Saiteihen Kishidan de Funsenchuu: Orc wo Chi no Hate Made Oishomete Zettai ni Hajime Hitsuji Suru Take no Kantan? na Oshigoto desu

The “Royal Order for the Prevention of Dangerous Invasive Species” was formed to protect the people against dangerous demons and monsters. However, it is a super-black workplace that offers no prestige for its knights...! Orcs and other vermin that never stop coming no matter how many they kill, wages that never increase, and quirky coworkers.... This is the story of the greatest swordsman who comes from a commoner background, working hard every day to cut down orcs as a bottom-tier knight in what is derisively called the "pig-hunting squadron."
