Just when Allen and the No-life Gamers think they've finally bought themselves some time to savor clearing of the Rank S dungeon, they receive a call for help from the Holy Land of Elmahl. The execution of the Pontiff of Daemonism has failed, and the capital has gone up in flames. Worse yet, just as the Gamers prepare to depart, reports begin pouring in about multiple invasions by the Demon Lord Army...

As Allen embarks on his latest adventure, he also finds himself confronted with the challenge of what it means to be a leader and learning to respect his friends' wishes—even if it means allowing one of them to knowingly put their life on the line!
