Suginami Subjugation Officer: The People on Dungeon Duty

In Japan, the existence of dungeons overrun by monsters has become part of everyday life. Dealing with them has turned into a government job, handled by public officers in the so-called “Conquest Division.” Yuma Yunagi, a trainee subjugator who dreams of becoming a hero, takes on dungeon raids as part of his regular five-day workweek. Partnered with Yonaga, who's low on outward passion but surprisingly caring toward his juniors, Yuma tackles the other worlds one assignment at a time!
