Tamer Knight: Frontier Defense

Bang Ho-young, once a gamer who lived for grinding rewards, suddenly awakens inside the very game he used to play. After angering the queen, he is cast out and appointed as the Frontier Lord, the so-called Border Count. His fiefdom is nothing more than a ruined wasteland endlessly threatened by monster invasions. With nothing to rely on except his unique skill [Conversion], which allows him to tame monsters, he must turn former enemies into allies in order to rebuild his land and protect it from destruction.
