Skull Clan unleashes a highest-level Zombie Horde that silenced two teams. The Sect Master refuses to retreat, calling the swarm a 'treasure trove' and insists on harvesting potential disciples. His device detects Riley Lynch as a candidate, but the recruitment condition is bizarre: 'Spank her butt for three minutes.' He orders Ivy and Lana to guard him and summons an SS-rank superhuman to demonstrate ability. Instead of combat, the SS-rank begins the three-minute test - apparently spanking a zombie - provoking shock from onlookers. The episode ends with the team stunned as the perilous, unorthodox trial starts amid the horde.
