This Warden Is Clearly Weak, Yet Absurdly Powerful

Clian transmigrates to a world of swords and magic. Humans, giants, fairies, demons, and dragons all coexist, while monsters of every kind run rampant. In the remote little city where Clian lives, there are five powers no one dares offend: the Immortal Witch's Inn, the Playful Fairy's Maze, the Fairest Exchange, the Adventurers' Tavern, and the Prison for Sinners. And Clian is the warden of the Prison for Sinners. Clian knows that the prison is alive, and that every month it captures monsters from who knows where... and not just monsters. A year after he arrived in this world, the prison captured a dragon, a member of the race that stands at the very pinnacle of the world. Subdue it or kill it: those are the choices facing Clian. But after Clian makes his choice, the prisoners captured by the prison become increasingly outrageous. “Light novel + everyday life + combat that isn't cathartic” Feel free to add it to your library.
